US plans for rapid vaccine rollout as COVID-19 surges to new heights

With outgoing President Donald Trump's coronavirus strategy relying heavily on a vaccine, the chief adviser of his administration's Operation Warp Speed program said on Tuesday that 20 million people could be inoculated by the end of 2020, and that by the middle of 2021 most Americans will have access to highly effective vaccines.

U.S. officials on Tuesday unveiled plans to begin vaccinating millions of Americans against COVID-19 as early as mid-December, as coronavirus infections and hospitalizations in the United States soared once more to unprecedented heights.

With outgoing President Donald Trump's coronavirus strategy relying heavily on a vaccine, the chief adviser of his administration's Operation Warp Speed program said on Tuesday that 20 million people could be inoculated by the end of 2020, and that by the middle of 2021 most Americans will have access to highly effective vaccines.

"Within 24 hours, maybe at most 36 to 48 hours, from the approval, the vaccine can be in people's arms," Moncef Slaoui, a former GlaxoSmithKline executive, said at an event conducted by The Washington Post newspaper.

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.
