Pfizer seeking FDA OK for COVID-19 vaccine booster dose

UNDATED (AP)- Pfizer is seeking U.S. approval of a booster dose of its two-shot COVID-19 vaccine. The drugmaker announced Wednesday that it has started the approval process for a third dose of its vaccine for Americans ages 16 and older. The company said it expects to complete its application with the Food and Drug Administration by the end of this week. U.S. health officials announced last week plans to dispense COVID-19 booster shots to all Americans to shore up their protection amid the surging delta variant of the virus. Pfizer’s vaccine received full regulatory approval this week.
