COVID booster shots are music to the ears of investors, but scientists warn trying to outsmart the virus with booster shots could create new variants, each more virulent and transmissible than the one before.
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.”
