SEATTLE, Wash. – A doctor at Seattle’s Fred Hutchinson Cancer Research Center says it’s time to start giving booster shots.

Dr. Larry Corey has overseen COVID-19 vaccine clinical trials and tells KIRO News that boosters of the Pfizer vaccine increase antibodies more than five times higher than the initial doses.

That would keep more people from getting infected.

“If you acquire it, you can’t get infected and you’re not getting infected, you won’t transmit it,” says Corey. “And we will start seeing a reduced circulation.”

He’d like to see boosters start for people 30-years-old and up.

The FDA will hold a meeting Friday, September 17th, to consider Pfizer’s application for a booster of its vaccine.
