The Food and Drug Administration says it has decided to continue approving COVID-19 vaccine updates for seniors and others at higher risk of severe disease, but will require vaccine makers to conduct major new clinical trials before approving them for wider use.

According to ABC News, the FDA has declared that the only groups of people who may receive unrestricted access to the COVID-19 vaccine are adults 65 years of age and older, as well as individuals with "underlying health conditions."
