Booster Shots a Likely Reality for COVID-Vaccinated Americans

FRIDAY, April 16, 2021 (HealthDay News) -- Vaccinated Americans will probably need booster shots to guard against emerging coronavirus variants in the future, a White House adviser and Pfizer's CEO said Thursday.

The United States is already planning for future booster shots, Dr. David Kessler, chief science officer for the pandemic response, said during a House subcommittee hearing on the country's vaccination efforts.

And in remarks released Thursday, Pfizer CEO Albert Bourla said the most likely scenario included the need for a third vaccine dose six to 12 months after initial inoculation, after which "there will be an annual revaccination."
