Pfizer asked U.S. regulators last week to allow boosters of its COVID-19 vaccine for anyone 18 or older, a step that comes amid concern about increased spread of the coronavirus with holiday travel and gatherings.
Older Americans and other groups particularly vulnerable to the virus have had access to a third dose of the Pfizer and BioNTech vaccine since September.
