EU regulator backs using Pfizer COVID shot as booster after other vaccines

A European Medicines Agency committee on Friday recommended approving the use of Pfizer and BioNtech's COVID-19 vaccine, Comirnaty, as a booster for adults who have previously been inoculated with other vaccines.

The recommendation from Europe's drug regulator comes days after the two companies showed that a third dose of their shot produced significant protection against the Omicron variant of the coronavirus in healthy children aged five to 11.
