CDC director offers stark reassurance: Only unvaccinated people are at risk by unmasking

The head of the Centers for Disease Control and Prevention, facing blowback over the agency’s new liberalized mask guidelines, offered a stark reassurance Sunday: Only unvaccinated people are at risk if they take off their masks.

“If you are vaccinated, we are saying you are safe, you can take up your mask and you are not at risk of severe disease or hospitalization from COVID-19,” the CDC director, Rochelle Walensky, said on “Fox News Sunday.” “If you are not vaccinated, you are not safe. Please go get vaccinated or continue to wear your mask.”

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.
