Vaccination QR Codes: What are They?

In response to the deadly SARS-Cov-2 pandemic, scientists and governments worldwide have devised vaccines that are gradually being rolled out in countries like the UK, USA, and India, to name a few. 

Although most governments have data repositories, they are primarily paper records, and they are not sufficient. So, how can governments keep track of vaccine drives, grant access to travelers, and authenticate the vaccine vial? 

Vaccination QR Codes.

Several companies and technology groups have begun developing apps and systems to check against themselves, creating digital health credentials or vaccination QR Codes. But, what exactly are vaccination QR Codes?

What is a vaccination QR Code and a vaccination passport QR Code?

Most COVID-19 vaccines are leveraging technologies such as barcodes and QR Codes, which weren’t used mainly in clinical care previously.

Vaccination QR Codes are QR Codes embedded on vaccination vials or secondary packaging of the vials to track the vaccine’s chain supply and verify its authenticity. 

Several governments worldwide have authorized the usage of vaccination QR Codes after each dose is administered to its citizens as a part of its vaccination drive for easy traceability.

Vaccination passport QR Codes are health QR Codes on passports and travel passes that have to be presented to enter countries, establishments, and venues, which assures that the user is vaccinated against COVID-19 and is free of the disease. 

Apps such as CO-WIN, IBM’s Digital Health Pass, and The Common Pass have been developed in a bid to offer digital health certificates entailing vaccination QR Codes on them. 

Vaccination passport QR Codes can be presented to authorities without revealing sensitive information. 

How are vaccination QR Codes and vaccination passport QR Codes being used across the globe? 

#1 Vaccination QR Codes on secondary packaging of vaccine vials

WHO strongly encourages the usage of vaccination QR Codes on secondary packaging of vaccine vials since QR Codes can provide instant access to electronic versions of printed information like labels and provide additional information about the vaccine that may not be printed on the vaccine. 

Vaccination QR Codes on secondary packaging of vial labels can guide health administrators of the route of administration, date of manufacture/expiration, doses per vial, temperature requirements, and batch number to facilitate vaccine management, 

Vaccination QR Codes can also enhance supply chain management to track and trace the inventory, provide leaflet information for training purposes, and access warehouse information. 

WHO also states that the substitution of QR Codes for statutory printed information is not an established system, creating liability risks, particularly around unauthorized users, thus making vaccination QR Codes the preferred tool on vaccine packages.

CDC adds QR Codes to Vaccine Information Statements (VIS)

CDC has added QR Codes to Vaccine Information Statements (VIS), including COVID-19 vaccines, namely Pfizer and Moderna, to help immunization providers record crucial information about the VIS as required by the National Childhood Vaccine Injury Act (NCVIA). 

These vaccination QR Codes allow health providers to scan the name and the VIS’s edition into an electronic medical record (IMR), IIS, or any other electronic device. 

#2 Vaccination passport QR Codes on digital health certificates

The primary application of the COVID-19 vaccine is to establish safety with precise immunization practices in place to stop the spread of the virus. 

To enter establishments, airports, sports venues, and restaurants, a certificate proving the individual’s immunization status must be presented. Paper certificates cannot be relied upon entirely because they can be easily misplaced and challenging to monitor. 

For this reason, vaccination passport QR Codes on digital health certificates are being employed by governments and provinces worldwide to ease the process of verifying the public.

A vaccination passport QR Code can be easily scanned by a smartphone, making it economical and reliable to permit access to establishments and venues. 

Usage of vaccination passport QR Codes in various countries

Several nations such as the United States, the United Kingdom, and India have established mandatory digital health certificates embellished with vaccination passport QR Codes to permit admission to their countries. 

In conjunction with each other, companies and governments have begun developing apps and digital systems using QR Codes for people to upload their COVID-19 data, including vaccinations, to allow into establishments. 

Let’s look at the usage of vaccination passport QR Codes in the following countries – 

The United States 

Vaccination passport QR Code in the US


As the United States distributes vaccines for the virus, a digital health credential is essential for reopening its economy to normal. 

Several airlines, including United, JetBlue, and Lufthansa, are planning on introducing the health passport app called CommonPass to verify their travelers’ virus test results and, soon, vaccinations.   

CommonPass, an app created by the Common Trust Network, enables individuals to upload their medical data such as their vaccination proof and COVID-19 test results and then converts the data in the form of a QR Code, which can be presented to authorities. 

These digital passes or vaccination passport QR Codes can help people enter stadiums, movie theatres, concerts, and even for traveling with ease. 

The United Kingdom 

Vaccination passport QR Code in the UK


The UK government already uses QR Codes for their NHS COVID-19 tracking app to trace its users of their health status and possible exposure to the virus. 

Baroness Harding, leading the government’s testing and tracing effort, has the Immunity Certificate as part of her remit. On November 17th, 2020, the Telegraph reported that the government ministers were discussing issuing vaccination passport QR Codes to allow entry to high-risk venues and events. 

The United Kingdom government later handed two firms the responsibility to begin exploratory work on an app to authenticate proof of vaccination to COVID-19. 

VST Enterprises developed a digital health passport and wallet, the V-Health Passport that converts the digital health certificate to a QR Code to authenticate its COVID-19 test results and vaccination. 

The V-Health Passport also has its tracing capabilities using anonymized data to protect its citizens’ data and privacy with the concept of self-sovereign identity. 

Citizens can use the app to prove their immunization status and present their COVID-19 results to authorities across the country and even for safe traveling. 


Vaccination passport QR Code in India


As the COVID-19 vaccinations are nearly here, the Indian government is preparing for a colossal vaccination drive across the country. 

Some of the measures implemented are likely to include SMEs delivered to beneficiaries days before the vaccination and a QR Code certificate after each dosage is administered. 

A key feature of the vaccination drive is to track the individual is likely to be added to the eVIN (Electronic Vaccine Intelligence Network) that tracks the reserve digitally. The system is scheduled to generate a QR Code health certificate for users as proof of vaccination. 

According to the Hindustan Times, all vaccine beneficiaries in Maharashtra will be assigned a QR Code-based vaccination certificate to prove their COVID-19 immunization. 

The Co-WIN app, a repurposed form of the eVIN platform, is officially recommended by the government for citizens to use. The app includes various features such as automated session allocation, send SMSes in 12 languages that will be sent to health providers, and a QR Code-based vaccination certificate to store in their mobile phones. 

The downloaded vaccination passport QR Code can also be integrated to store and fetch with the government’s document storage app, DigiLocker. 

Union Health Minister Harsh Vardhan Thursday said, “This platform will assist the program managers across all levels through automated session allocation for pre-registered beneficiaries, their verification, and for generating a digital certificate upon successful completion of the vaccine schedule.”

Why are QR Codes the right fit for vaccination vials and certificates?

#1 Easy traceability 

QR Codes can be easily tracked and analyzed in real-time, making it a favorable tool for governments and companies to leverage the technology to track supply chain management. 

The WHO highly encourages vaccine manufacturers to embed QR Codes on their secondary packaging since they can be easily tracked and used to identify their unique serial numbers. 

Since all COVID-19 vaccination is supposed to follow the international standard regulations, vaccination QR Codes help government officials authenticate its manufacturing source and support ongoing efforts to scale up traceability systems in countries that receive COVID-19 vaccines. 

#2 Ensure the authenticity of vaccine vials

Vaccination QR Code to ensure authenticity of vaccines

COVID-19 vaccines are novel, meaning a lot of health workers and supply chain management are quite unaware of what the international regulations should be. 

Vaccine QR Codes on secondary packaging of vaccine vials are intended to provide instant access to essential information such as labels and leaflets that are not available on the product packaging, such as date of package/expiry, batch number, procurement source, appropriate temperature storage, and supplementary information. 

Separate guidance to include statutory label requirements, including communication changes, has been added to the vaccination QR Codes. 

In addition, vaccination QR Codes offer multi-language support, making it a highly viable tool to be supplied in various countries. 

#3 Economical 

Scanning QR Codes do not require additional hardware and tools/system, since smartphones can scan QR Codes via their cameras making them the go-to tool for accessing vital information about the vaccine, traceability, and even register. 

Vaccination QR Codes allow healthcare professionals to learn more content density like vaccine identification, serialization, statutory regulations, batch number, and even quality only by scanning the QR Code. 

Can vaccination QR Codes be promising? 

The arrival of the COVID-19 vaccination shows a promising future for governments, employers, businesses, and the general public by restoring the economy to normal. Electronic vaccination credentials or having an app to prove immunization status could profoundly impact efforts to control the virus.

However, having a mandatory app for digital passes raises a community’s specter into haves and have-nots, particularly if establishments begin demanding these apps as entry tickets. 

Vaccination QR Codes can be leveraged in places of these apps to make it easier for authorities and people with limited access to online vaccination certificates to enter venues without a hitch. 

The fact that vaccination QR Codes are being favored by several nations to prove their public’s proof of immunization and health status, trace easily, and distribute the vaccines easily demonstrates promising results for countries and their people.
