The drugmaker has the best-selling vaccine to prevent COVID and the most effective drug to treat it. Its success and might have overshadowed the government’s COVID-fighting strategy.

As the Food and Drug Administration weighs approval of COVID-19 vaccinations for children under age 5, Florida Surgeon General Joseph Ladapo is opposed to the potential change.

Pfizer plans to submit new data to the Food and Drug Administration this week, bringing families with young children one step closer to a long-awaited vaccine.

The Centers for Disease Control and Prevention's advice opens a third COVID-19 shot to healthy elementary-age kids — just like what is already recommended for everybody 12 and older.

Doctors have begun reporting cases of patients who see their symptoms return several days after treatment.

The federal “test-to-treat” program was designed to be a one-stop shop for people to get tested and receive treatment. But as cases rise again, many communities have no participating locations, and website bugs make it difficult to book an appointment at the biggest participant.

Pfizer and BioNTech are planning to ask the Food and Drug Administration to authorize a second COVID-19 booster shot for people age 65 and older.

New research out of New York found the protection of the vaccine against infection in kids who got the lowest dose dropped from 68% to 12%.
