Amid evolving strains, COVID-19 vaccines likely need updates every 3 years, former FDA chief Gottlieb says
Dec. 21, 2020
“Former Food and Drug Administration Commissioner Scott Gottlieb said Monday coronavirus vaccines will likely require updates every few years as surface proteins on the virus evolve to become unrecognizable to antibodies.
Gottlieb told CNBC co-hosts that while current COVID-19 vaccines and prior immunity are likely effective against the newly mutated strain of the virus rapidly circulating in the U.K., the evolving virus will necessitate surveillance by sequencing.
"We thought every two, or maybe three years, I was saying that probably 6-8 months ago, every three years, that might still be the case," Gottlieb said, referring to a potential timeframe for updated COVID-19 vaccines. "I don’t think this is something we need to update every season, but if it becomes easy to update it, you may do that, you may look at what the predominant strain is and try to update it more regularly."“

"Eventually we'll get into a framework with COVID--we'll accept that if a vaccine can induce a certain level of antibodies it is going to be effective and therefore allow updates based on antibody response," says
