Vaccines are delicate biological substances that gradually become inactive over time and must be kept under a recommended temperature range of 2-8 °C for both short and long-term storage. Exposure to heat or freezing temperatures can highly affect the immunological properties of these vaccines and make them completely ineffective. Research shows that vaccine exposure to temperatures outside the recommended range is 33% in developed countries and 37.1% in developing countries. In practice, vaccines are stored in refrigerators, while thermometers and data loggers are used to record and monitor temperatures. However, traditional systems are unreliable due to lack of battery backup, human error, periodic logging of temperatures, etc. Therefore, an effective and reliable vaccine tracking and monitoring system is urgently needed. This paper proposes a blockchain-based, smart contract enabled solution that ensures an enhanced level of security, transparency, and traceability of stored vaccines in a health clinic, and enables the complete history of every vaccine to be checked from the day the vaccine is received by the health clinic to the date it is used or expires. We also formally analyze the resiliency of the proposed system against several attacks and compare the system with existing blockchain and non-blockchain-based solutions.
Infectious and contagious diseases exist in humanity for many centuries which causes a curb in the growth of the population. Immunization plays a vital role to prevent mortality and morbidity against infectious diseases. COVID-19 pandemic continues to rage the urgency of developing a vaccine that should ensure the safety, efficacy, swift and fair deployment, implementation, and monitoring of vaccines across the globe. In the present context, the vaccine production to immunization campaign is a critical challenge. Therefore, an effective vaccine supply chain mechanism is required to address issues such as counterfeit vaccines, reduce vaccine wastages, and vaccine record fraud. In this paper, a blockchain-enabled vaccine supply chain is proposed to ensure the correctness, transparency, trust, and immutable log and improve the efficiency of vaccine distribution in the cold chain. The uniqueness of the proposed system is to provide distributed system to verify the reliability and efficacy of the vaccine from production to end beneficiaries' feedback about the vaccine. Our proposed system gives a clear view to the users as well as to the healthcare provider about the vaccination and ensures the anticounterfeit vaccine. The proposed system minimizes counterfeit vaccines and records, provides transparent communication between stakeholders in the supply chain, and improves the security of the vaccine supply chain and immutable feedback system about the vaccine.
Electronic vaccine certificates (EVC) for COVID-19 vaccination are likely to become widespread. Blockchain (BC) is an electronic immutable distributed ledger and is one of the more common proposed EVC platform options. However, the principles of blockchain are not widely understood by public health and medical professionals. We attempt to describe, in an accessible style, how BC works and the potential benefits and drawbacks in its use for EVCs. Our assessment is BC technology is not well suited to be used for EVCs. Overall, blockchain technology is based on two key principles: the use of cryptography, and a distributed immutable ledger in the format of blockchains. While the use of cryptography can provide ease of sharing vaccination records while maintaining privacy, EVCs require some amount of contribution from a centralized authority to confirm vaccine status; this is partly because these authorities are responsible for the distribution and often the administration of the vaccine. Having the data distributed makes the role of a centralized authority less effective. We concluded there are alternative ways to use cryptography outside of a BC that allow a centralized authority to better participate, which seems necessary for an EVC platform to be of practical use.
With regards to the COVID-19 pandemic, the fast carry out of an antibody and the execution of an overall vaccination crusade is basic, yet its prosperity will rely upon the accessibility of a functional and straightforward circulation chain that can be evaluated by all applicable partners. In this paper, we examine how blockchain innovation can help in a few parts of COVID-19 inoculation conspire. We present a framework in which blockchain innovation is utilized to surety information honesty and permanence of recipient enlistment for immunization, keeping away from character burglaries and pantomimes. Smart contracts are characterized to screen and track the legitimate antibody dissemination conditions against the protected dealing with rules characterized by antibody makers empowering the familiarity with all organization peers. For immunization organizations, a straightforward and sealed answer for aftereffects self-detailing is given by thinking about the recipient, what's more, administrated antibody affiliation. A model was executed utilizing the Ethereum test organization, Ropsten, considering the COVID-19 immunization dissemination conditions. The outcomes acquired for each on-chain activity can be checked and approved on the Etherscan. Regarding throughput and versatility, the proposed blockchain framework shows promising outcomes while the assessed cost concerning gas for inoculation situation in view of genuine information stays inside sensible cutoff points.

COVID-19 has changed almost all aspects of our lives. Governments around the world have imposed lockdowns to slow down the transmissions. Fortunately, we have found the vaccine, in fact, a good number of them. However, managing the testing and vaccination process of the total population is a mammoth job. However, there are always delays or data silo problems in multi-organizational work. Therefore, streamlining this process is vital to improve efficiency and save more lives. Because of its effective data sharing mechanism among different entities with a number of security features, blockchain can be an effective tool for different applications in the health sector. Furthermore, blockchain provides a distributed system along with greater privacy, transparency, and authenticity. In this article, we have presented a blockchain-based system that seamlessly integrates testing and vaccination systems, allowing the system to be transparent. The instant verification of any tamper-proof COVID-19 test result has been developed, which will serve as “Test Certificates”. A transparent and efficient vaccination system has also been exhibited and implemented as the “Digital Vaccine Passport” (DVP) system. The infection rate-based prioritization will ensure a transparent and fair vaccination process as well as tackle the distribution issue of the limited amount of vaccine. The comparative review with other existing works is also discussed, highlighting a clear difference from the existing works. Our proposed system is distinctive on the basis of prioritization of vaccines and seamless integration of test certificates and vaccine passports, which will aid in controlling the pandemic situation. This system will also be handy in the case of tackling any future pandemics initially.
Photo by Mufid Majnun on Unsplash INTRODUCTION In 2007, the Nuffield Council of Bioethics introduced the “Intervention ladder” as a guiding framework[1] to evaluate the impact on individual liberty of various public health measures. One criticism of the ladder is that it reflects a narrow view of liberty, yet other researchers adapted the intervention ladder to incorporate a more autonomy-based view. Recently, academics and public health officials have used intervention ladders as guides in framing policies, particularly COVID-19 pandemic policies.[2] Analyzing the Indian COVID-19 vaccination drive under these two ladders can illuminate the concepts of liberty underlying those ladders and help determine the best framework on a philosophical basis. ANALYSIS l. Case Study: The Indian COVID-19 Vaccination Drive On January 16, 2021, India attempted a public vaccination drive.[3] The drug regulatory body Central Drugs Standards Control Organization (CDSCO) approved two vaccines, Covishield and Covaxin, for emergency use.[4] The approval was granted despite a clear lack of phase 3 clinical trial data for both of these vaccines.[5] Covishield, produced by the Serum Institute of India, is the Indian variant of the Astra-Zeneca vaccine that has shown an average efficiency of 70.4 percent after trials in the UK.[6] Covaxin, manufactured by Bharat Biotech in collaboration with the Indian Council of Medical Research (ICMR) National Institute of Virology, was developed and manufactured in India. [7] Covishield relied on the safety and efficacy data from large trials conducted in Brazil, South Africa, and the UK with 24,000 participants and a small cohort for the Indian study. Covaxin was given approval based only on phase-1 trial data. [8] An article published in The Lancet called for further efficacy data from the Covaxin study.[9] The officials associated with Bharat Biotech, as well as the Indian Council of Medical Research, maintained that fast production of the vaccine does not indicate a compromise in safety, even though they had little data to produce.[10] However, transparency is key to vaccination policy, which requires public participation. The media reported that the Covaxin clinical trials compromised research integrity by providing a monetary incentive of around 7 euros, to research subjects. People’s University, a private medical college, and hospital, recruited survivors of the Bhopal Gas tragedy for the Covaxin study. The participants were told that they were being provided a vaccine against COVID-19 without clarifying that data was being collected for their clinical study. There was no record of informed consent from these participants for the Covaxin study.[11] The media reported the death of a 42-year-old individual who received his first dose on December 23, 2020. [12] Although it was reported that the cause of death was not linked to the vaccine, the death added to vaccine hesitancy. The vaccines were provided for free to the frontline healthcare workers with no choice on which vaccine the recipients would receive.[13] Similarly, in the US, some people do not have a choice between Pfizer or Moderna. In the UK and the US, data from phase 3 trials are known with a periodic follow-up after the administration of the second dose.[14] The WHO developed a tracking system for COVID-19 vaccine recipients which was updated on March 19, 2021, to reflect the results of Covaxin phase 3 trials.[15] India eliminated choice although the two vaccines approved for emergency use did not have the depth of research that those used elsewhere had. The intervention ladder, discussed below, which uses proportionality and the harm principle to justify the lack of choice between the vaccines in the UK and the US, should not be applied to India’s vaccination policy. ll. The Nuffield Intervention Ladder The foundational principle underlying the Nuffield Intervention Ladder is Mill’s conception of individual liberty from the prominent work, On Liberty.[16] However, the Council recognizes that the intervention ladder is conceived on a broader interpretation of Mill’s liberty, using the principle of proportionality as a tool for justification i.e., the desired effect from the intervention is proportional to the loss incurred in liberty.[17] As shown in Table 1, an ideal intervention that is least infringing would then be no intervention at all. An intervention that would be more difficult to justify would be one that significantly restricts individual liberty. Intuitively, eliminating occupies the topmost rung on the ladder. The metaphor of the ladder suggests that as one climbs up the rungs of the ladder, stronger justifications would be required. Table 1: Examples of interventions at each level of the intervention ladder adapted and improvised from the Nuffield Council of Bioethics Report, 2007. A voluntary vaccination policy is one public health intervention that is acceptable and justifiable in terms of the principle of proportionality as well as Mill’s Harm Principle, with emphasis on diminishing individual liberties when actions might result in harm to others.[18] Although a vaccination policy in the context of a global pandemic seems justifiable through the lens of the intervention ladder, the Indian modus operandi is unique because of inherent problems with the original conception of the intervention ladder. By pausing to elaborate and reflect on the Indian context as a case study, we can demonstrate that individual liberty should not be the sole variable in framing justifiability. lll. Critiquing the Nuffield Intervention Ladder & Adding a Precautionary Approach In his paper, ‘Snakes and Ladders: State Interventions and the Place of Liberty in Public Health Policy’, Angus Dawson criticizes the intervention ladder’s focus on individual liberty,.[19] and its inability to account for the different treatment of incentives and disincentives and the role of information. Public health institutions require public participation to restrict the infectious spread of COVID-19. The lack of transparency and minimal information surrounding the vaccines have been a major hurdle in increasing public participation. It is contradictory to think that the public does not require information about interventions and have the ability of self-determination to guide them, when in fact self-determination presupposes possession of relevant information. A voluntary vaccination policy can be seen as sitting on either the lowest rung (providing information) or the rung of enabling choice, as a vaccination campaign does both. However, in India, the precautionary principle should also be applied as providing the choice should not permit ‘harm’. The precautionary principle holds that anything that poses a risk to human health or the environment should be avoided or accompanied by precautionary measures. In India, because the clinical trials were smaller and there is less proof of safety and efficacy, a vaccination requirement, or a public health campaign to encourage vaccination violates the principle. The proportionality principle governing the intervention ladder only requires that the benefits of the intervention justify the restrictions on liberty. The intervention ladder should prevent requiring healthcare worker vaccination without a choice of vaccine because a free choice requires transparency and more information than is available from the small early-stage clinical trials. Actions surrounding the vaccines in India do not reflect proper precaution or a proportionate and thus acceptable restriction on liberty. If there is no ability to choose between the two possible vaccines, then they should not be mandatory for healthcare workers. The Indian government and its officials have urged healthcare worker compliance by invoking the seriousness of the pandemic and the alarming rates of mortality rather than providing transparent data pursuant to the regulatory mechanisms of the vaccine clinical trial. For a healthcare worker, the duty to provide service and a stronger obligation to do so in the time of a pandemic already imposes certain restrictions on their liberty. The lack of choice in opting for a preferred vaccine puts it on a higher rung on the intervention ladder and thus requires stronger justifications. This case study reveals how the same public health intervention falls on different rungs of the intervention ladder depending on the target group in consideration. Or to put this simply, choice is contextual. Table 2: The ethical values at stake when it comes to “choice” lV. An Autonomy-Based Intervention Ladder Liberty and autonomy differ slightly: liberty revolves around the constraints on the ability to act, whereas autonomy stresses on the independence and the authenticity of the willingness to act.[20] It is thus possible for an individual to be autonomous but unfree, as can be seen from the inability to opt for a preferred vaccine.[21] Figure 1 shows an adapted schematic of an autonomy-based intervention ladder as proposed by Griffiths et al. Figure 1: An adapted schematic of the autonomy-based intervention ladder proposed by Griffiths, P.E and West, C. In comparing the original intervention ladder with their proposal, we see that the autonomy-based model allows for a negative scale in terms of its effects on autonomy. Thus, on this ladder, actions can be autonomy-enhancing or autonomy-diminishing. Such a model challenges the one-directional view of the ladder and rearranges interventions on a scale that ranges from negative to positive. A few interventions that were shown to have restrictive effects on liberty now have reinforcing effects when viewed through the lens of autonomy. Thus, providing information and educating can be seen as positive reinforcements for autonomous choice rather than infringing on individual liberty. The autonomy-based intervention ladder requires the State to implement inte

In late 2019, we witnessed the apparition of the covid-19 virus. The virus appeared first in Wuhan, and due to people travel was spread worldwide. Exponential spread as well as high mortality rates, the two characteristics of the SARS-CoV-2 virus that pushed the entire world into a global lock-down. Health and economic crisis, along with social distancing have put the globe in a highly challenging situation. Unprecedented pressure on the health care system exposed many loopholes not only in this industry but many other sectors, which resulted in a set of new challenges that researchers and scientists among others must face. In all these circumstances, we could attend, in a surprisingly short amount of time, the creation of multiple vaccine candidates. The vaccines were clinically tested and approved, which brought us to the phase of vaccination. Safety, security, transparency, and traceability are highly required in this context. As a contribution to assure an efficient vaccination campaign, in this paper we suggest a Blockchain-based system to manage the registration, storage, and distribution of the vaccines. This manuscript has been presented as preprint in Blockchain technology for a Safe and Transparent Covid-19 Vaccination: https://arxiv.org/abs/2104.05428
Transforming a vaccine concept into a real vaccine product is a complicated process and includes finding suitable antigens and regulatory, technical, and manufacturing obstacles. A relevant issue within this scope is the clinical trial process. Monitoring and ensuring the integrity of trial data using the traditional system is not always feasible. The search for a vaccine against the coronavirus SARS-CoV-2 illustrates this situation. The scientific credibility of findings from several vaccines' clinical trials contributed to distorted perceptions concerning the benefits and risks of the drug. This scenario is ideal for applying technologies such as Blockchain and Smart Contracts in healthcare issues. This paper proposes a protocol based on Smart Contracts, named VaccSC, to enable transparency, accounting, and confidentiality to Phase III of vaccine experiments. The protocol was implemented in Solidity language, and results show that the VaccSC enables double-blindness, randomization, and the auditability of clinical data, even in the presence of dishonest participants.
Because a fast vaccination rollout against coronavirus disease 2019 (COVID-19) is critical to restore daily life and avoid virus mutations, it is tempting to have a relaxed vaccination-administration management system. However, a rigorous management system can support the enforcement of preventive measures, and in turn, reduce incidence and deaths. Here, we model a trustable and reliable management system based on blockchain for vaccine distribution by extending the Susceptible-Exposed-Infected-Recovery (SEIR) model. The model includes prevention measures such as mask-wearing, social distancing, vaccination rate, and vaccination efficiency. It also considers negative social behavior, such as violations of social distance and attempts of using illegitimate vaccination proofs. By evaluating the model, we show that the proposed system can reduce up to 2.5 million cases and half a million deaths in the most demanding scenarios.

The first cases of COVID-19 pandemic were identified in people with pneumonia in Wuhan, China, in late December 2019. It is first and foremost the most publicized pandemic, which has taken the lives of many people. It has thrown everyone into doubt and has created a collective moment of contemplation about the future. The clinical enlistment organization MedWorld of New Zealand offered for resigned and low maintenance specialists to help endeavors by the health care division and Government to battle the spread of COVID-19, in New Zealand. (11“COVID-19 Pandemic in New Zealand.”) Starting in April, more than 20,000 tests have been done in Iraq in general (counting the Kurdistan Region), with 1202 of them turning out positive. Of those tests, half of the,m were finished by the Kurdish Ministry of Health, which implies that the other tests were finished by the Iraqi Ministry of Health. (22“COVID-19 Pandemic in Iraq.”) While KRG populace has been tried, just 0.05% of the remainder of the nation has been tried, along these lines featuring the conceivable difference between absolute positive case numbers between locales. Iraq is considered ”particularly powerless against the plague due to being desolated” – by war and United Nations sanctions, and by partisan clash in the course of recent decades. This paper primarily focuses on analyzing the accessible information through research papers, peer- reviewed and non-peer reviewed to understand the pandemic affecting two different countries like New Zealand- a developed country and Iraq- a developing country.1.2. Aim: The aim of this study is to provide information and access the current status of medical management in a developed country like New Zealand and a developing country like Iraq, based on current medical literature available. 1.3. Material used: The following review paper has considered published peer- reviewed papers and non peer-reviewed pre-print manuscripts on COVID-19 and related aspects with primary focus on preventive medicine. 1.4. Study Methodology: This retrospective view focuses on understanding the different preventive strategies implemented by the countries with different socio-economical backgrounds. 1.5. Preliminary thesis: The review paper focuses on comparing the strategic management and elimination of COVID-19, in the two countries, i.e. New Zealand and Iraq, in a public health and preventive medicine perspective.Introduction- 2.1. What is corona virus? Coronaviridae is a large family of viruses that cause mild to moderate upper-respiratory tract illnesses like the common cold. They are named for the crown-like spikes on their surfaces as seen on the electron microscope. In some cases these viruses infect the humans, which is called a spillover event and can cause several diseases. The international committee for the taxonomy of viruses has approved the naming of more than 40 corona viruses, majority of which infect animals, and lead to human transmission. The COVID-19 outbreak has brought the number of identified corona viruses that can infect humans to seven, out of which, four are community acquired. The other three are SARS-CoV, MERS-CoV and SARV-CoV-2, which has resulted in the highest mortality rate. Covid-19 or previously known as Novel corona virus is a new strain of coronavirus that first emerged in Hubei provenience in China in the late 2019. It is predominantly spread by respiratory droplets and from contact to contaminated surfaces. The spread is similar to that of influenza virus, so practicing same precautions as to prevent the influenza virus can provide protection against Covid-19. The most common symptoms are cough, severe dyspnea, fever, chills, myalgia, sore throat, congestion or runny nose. Majority of the cases have milder diseases with few having severe diseases which lead to pneumonia and respiratory failure. Deaths have generally occurred in older population, and in patients having underlining health conditions. Reports of severe cases in children are uncommon. Currently the treatment is supportive, but severe cases may require intensive care. (33Cui, Li, and Shi, “Origin and Evolution of Pathogenic Coronaviruses.”)(44Masters, “The Molecular Biology of Coronaviruses.”) Impact of corona virus pandemic on New Zealand: New Zealand recorded its first day of no new instances of coronavirus infection 2019 (COVID-19), more than a month after its severe lockdown started. New Zealand had recorded from less than 1200 affirmed instances of COVID-19, 20 deaths. On March 23, a month to the first case reported, New Zealand focused on a disposal system. A couple of days afterward, Prime Minister Jacinda Ardern declared a public lockdown at the point when it just had 102 cases and zero deaths. Her quick decision won universal recognition, including from WHO. New Zealand’s choice to seek after an end approach was a diverse way to deal with regular pandemic arranging, which has generally been in light of an alleviation model and centers around postponing the appearance of the infection, trailed by a scope of measures to level the bend of cases and passings. Michael Baker, teacher at the College of Otago’s specialty of general healthcare in Wellington, who has been exhorting the New Zealand Government on its reaction. ”The two greatest advantages of seeking after a disposal system is that you have barely any cases and hardly any deaths and you can get business back fully operational. The elective was that we are left with the infection and stuck between relief furthermore, concealment. Concealment is lovely terrible .” (55“Coronavirus Outbreak: Live Updates on COVID-19.”) While the methodology has had its experts, for Baker, the proof was overpowering that end could be accomplished. The full lockdown permitted the nation to get the major frameworks up and rushing to viably oversee fringes, furthermore, to do contact tracing, testing, and observation. Since January, more than half a million individuals have been tried in a nation of only 5 million. Testing has been centered around individuals who have presenting symptoms, with following of both close contacts and easygoing contacts. But currently, more broad testing has being presented. The Ministry of Health is in conversation with regions to organize testing of explicit networks who are at higher danger of gaining the infection such as human services laborers. Testing tests from sewerage is additionally being thought of to screen control and disposal. The reaction has additionally been one that set science, authority, and cautious language at the front line. Ardern has consistently showed up on online media, grinning and sharing parts of her own life under lockdown yet without underplaying the earnestness of the circumstance, which has served to construct open trust. Travelers from abroad are to be isolated as a major aspect of endeavors to forestall transmission in New Zealand. As New Zealand currently facilitates its limitations and its economy gradually resumes, there are conversations about how it can open up its fringes while guaranteeing that everybody is ensured, especially vulnerable populations. (66“(PDF) Coronavirus-19 Intervention Approach in New Zealand.”) Impact of corona virus pandemic on Iraq: On 31 December 2019, a group of pneumonia of obscure beginning was accounted for in Wuhan City, Hubei Province of the People’s Republic of China. On 11 March 2020, the World Health Organization’s (WHO) declared that the microorganism known as the Coronavirus Disease 2019 (COVID-19), established a pandemic. By 13 March, WHO announced that the expansion in instances of COVID-19 in the Eastern Mediterranean locale, including Iraq was ”of specific and incredible concern”. Starting at 20 April 2020, there were 1,539 affirmed instances of COVID-19 and 82 deaths in Iraq with the quantity of affirmed cases detailed expanding. The COVID-19 episode took steps to weaken the effectively delicate framework and effect the numerous networks who are as yet defenseless and recuperating from the Islamic State in Iraq and the Levant (ISIL) emergency and ensuing monetary downturn. The center public capacities with regards to anticipation, readiness and reaction, limit with regards to general wellbeing, and the medicinal services framework has been debilitated by years of contention, sanctions, helpless administration and low interests in wellbeing. There was an absence of wellbeing workforce across various units, with many having fled Iraq, and deficiencies in basic drugs and gear. The absence of open administrations, including medicinal services, were among the variables driving distress all through 2018, especially in the southern governorates. The exhibitions and related political flimsiness brought about the abdication of the Prime Minister. At the local and worldwide level, there are proceeded and rising strains among US and Iranian intermediaries; and ISIL have additionally expressed their expectation to abuse the current emergency, which could be especially horrendous for regular citizens seeking after an arrival to normalcy. Lengthy and permeable fringes aggravate the test of overseeing dangers related with human portability and episodes; Iraq has long land and ocean fringes with Iran, Jordan, Kuwait, Saudi Arabia, Syria and Turkey, with 26 Points of Entry (PoE), including five air terminals, six ports and 15 ground intersections that convey worldwide traffic. Iraq is a country with many travelers and hence a significant number of whom are trapped in emergency and in considerably more dubious conditions. Iraq additionally has hundreds of thousands of south Asian, southeast Asian and African traveler laborers utilized in the residential, development also, administration divisions, prone to disproportionally affected by the wellbeing emergency, financial downturn and travel limitations. Travelers and evacuees in Iraq, incorporating those in outcast camps who may have residency and money related status issues, are at uplifted hazard, especially with regards to air terminal terminations, travel limitations, the stopping of worldwide resettlement program and failure to execute helped willful return and reintegration (AVRR) programming. To help stop transmission, the Government of Iraq (GoI) including the Kurdistan Regional Government (KRG) have progressively implemented bans on travelers from countries with significant COVID-19 outbreaks from entering the country, quarantine requirements and closures of the main airports in Baghdad and Erbil. (77“WHO | Iraq Health Situation Reports.”)A Preventive Medicine perspective:How COVID pandemic has impacted New Zealand and their adopted policies and strategies: 3.1.1 Elimination strategy in New Zealand: The Government’s health policy methodology in regard of the COVID-19 pandemic influencing New Zealand is elimination. That is, to apply a scope of control measures all together to stop the transmission of COVID-19 in New Zealand. Disposal doesn’t mean annihilating the infection forever from New Zealand; rather it is being certain we have disposed of chains of transmission in our locale for at any rate 28 days and can successfully contain any future imported cases from abroad. It is acknowledged that this methodology will be required in the drawn out i.e., for a long time or more, contingent upon the developing the study of disease transmission and proof around the sickness and its the executives and progress with creating protected and powerful medicines and additionally antibodies.

Goal: As the Coronavirus Pandemic of 2019/2020 unfolds, a COVID-19 'Immunity Passport' has been mooted as a way to enable individuals to return back to work. While the quality of antibody testing, the availability of vaccines, and the likelihood of even attaining COVID-19 immunity continue to be researched, we address the issues involved in providing tamper-proof and privacy-preserving certification for test results and vaccinations. Methods: We developed a prototype mobile phone app and requisite decentralized server architecture that facilitates instant verification of tamper-proof test results. Personally identifiable information is only stored at the user's discretion, and the app allows the end-user selectively to present only the specific test result with no other personal information revealed. The architecture, designed for scalability, relies upon (a) the 2019 World Wide Web Consortium standard called 'Verifiable Credentials', (b) Tim Berners-Lee's decentralized personal data platform 'Solid', and (c) a Consortium Ethereum-based blockchain. Results: Our mobile phone app and decentralized server architecture enable the mixture of verifiability and privacy in a manner derived from public/private key pairs and digital signatures, generalized to avoid restrictive ownership of sensitive digital keys and/or data. Benchmark performance tests show it to scale linearly in the worst case, as significant processing is done locally on each app. For the test certificate Holder, Issuer (e.g. healthcare staff, pharmacy) and Verifier (e.g. employer), it is 'just another app' which takes only minutes to use. Conclusions: The app and decentralized server architecture offer a prototype proof of concept that is readily scalable, applicable generically, and in effect 'waiting in the wings' for the biological issues, plus key ethical issues raised in the discussion section, to be resolved.
