The US government will first give Americans COVID-19 vaccines, but any surplus would be shared with the world, President Joe Biden said on Wednesday after earlier announcing plans to procure an additional 100 million doses.

"We're going to start off and ensure Americans are taken care of first, but we’re then going to try to help the rest of the world," Biden told reporters following an earlier announcement to secure more vaccines with the chief executives of Johnson & Johnson and Merck.

"If we have a surplus, we're going to share it with the rest of the world," Biden said, adding that the United States had already committed to providing $4 billion to the COVAX global initiative to distribute vaccines in developing countries.

The Democratic president said it was clear that the pandemic would not be over until it was ended everywhere.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
