Vaccine makers are telling investors and the media that COVID booster shots are already in the works. In some cases, companies say the boosters may be needed because the vaccine’s effectiveness may run out. In other instances, they suggest booster shots will be needed to combat new COVID variants.
Annual COVID booster shots are music to the ears of investors. But some independent scientists warn that trying to outsmart the virus with booster shots designed to address the next variant could backfire, creating an endless wave of new variants, each more virulent and transmissible than the one before.
Pfizer CEO Albert Bourla said Thursday a third dose of the company’s COVID vaccine was “likely” to be needed within a year of the initial two-dose inoculation — followed by annual vaccinations.
Bourla said that “a likely scenario” is “a third dose somewhere between six and 12 months, and from there it would be an annual re-vaccination.”
In a conversation hosted by CVS Health, Bourla explained how some vaccines are given only once, while others need annual boosters like flu shots.
“It is extremely important to suppress the pool of people that can be susceptible to the virus,” Bourla said during an interview with CNBC. Booster shots will be an important tool in battling more contagious variants, he added.
