Is there a vaccine against COVID-19?

To date, career public servant-scientists at the US Food and Drug Administration (FDA) have granted Emergency Use Authorizations (EUAs) for both the Pfizer-BioNTech and Moderna COVID-19 vaccines. Before the EUAs were granted, independent experts serving on the FDA's vaccine advisory committee had voted overwhelming that, for people 16 years old and above (Pfizer-BioNTech), or 18 years old and above (Moderna), the benefits of the vaccines outweigh the risks. Canada and Britain have also cleared the Pfizer-BioNTech COVID-19 vaccine for use. There are limited doses of the vaccines, and it is expected the vaccines will first be made available to those considered most at risk to COVID-19 - health care workers and residents of long-term care facilities - although this will differ by state.
