SCIENCE & TECH SPOTLIGHT:
DIGITAL VACCINE
CREDENTIALS

What is it? A digital vaccine credential can be used to confirm a person's
identity and whether the person has been vaccinated for COVID-19.
Often referred to as vaccine passports, digital credentials can also include
information on whether the person has tested negative for or recovered
from COVID-19. Some countries and industries require proof of a negative
COVID-19 test or vaccination to mitigate transmission of the disease, and
view digital credentials as a tool to safely reopen societies and economies.
The concept of a health credential is not new. For example, a paper
vaccine certificate known as the yellow card has long been recognized
as an official record of immunizations for international travel and other
purposes. It was first created in 1933 by a precursor to the World Health
Organization (WHO).
How does it work? Generally, users of a digital credential would
download an application (app) onto a mobile device, create an account,
and link it to their COVID-19 vaccination record from an immunization
registry or to a COVID-19 test result from a certified test laboratory. A digital
credential confirms the user's identity and authenticates COVID-19 health
information. It also validates the health information against the destination's
entry requirements, such as specific vaccines or tests accepted by a
country. The app then generates a secure digital code the user can present
to, for example, airline staff at check-in before boarding a flight or border
control officials at an airport passport control checkpoint (see fig. 1).

F   . A simplified illustration of how a digital vaccine credential is created.
How mature is it? Public and private entities, both in the U.S. and other
countries, are developing and piloting digital credentials, but governance
frameworks and technical standards for the use of this new technology
are still emerging. As one of the industries hardest hit by the COVID-19

pandemic, and in anticipation of increased passenger travel in summer
2021, the aviation industry has led efforts to develop digital credentials to
facilitate safer and more efficient travel (see fig. 2). For example, in spring
2021, 50 international airlines were piloting the International Air Transport
Association's (IATA) Travel Pass for digital proof of COVID-19 testing.
IATA also announced plans to pilot the use of the Travel Pass for proof of
COVID-19 vaccination by summer 2021. Many other digital credentials are
being developed, piloted, and launched for use in the travel industry and
other sectors, such as the entertainment industry.

F   2 Use of digital credentials at airports could make departure and arrival procedures
faster and more efficient for travelers, airlines, and border officials compared to review and
verification of paper vaccine cards in different languages.
National governments are taking different approaches to this technology.
The U.S. government stated in spring 2021 that it planned to work with
private sector entities to develop common standards for digital credentials,
especially with regard to health data privacy, but would not create a
centralized federal vaccination database or mandate a national digital
credential. By comparison, several countries, including Denmark, Israel,
and the United Kingdom, are introducing or have launched national digital
credentials. The European Union (EU) announced plans to launch its
Digital Green Certificate in June 2021 for travel among member states.
The EU may also allow vaccinated Americans to travel to EU countries in
summer 2021.
