Not everyone agrees that COVID-19 booster shots are necessary for all vaccinated Americans. jaimy_lee takes a look at how boosters are more complicated than they appear:
Not everyone agrees that COVID-19 booster shots are necessary for all vaccinated Americans, and that discord may slow down plans to roll out extra doses of the mRNA vaccines later this month and change who is eligible for them.
That said, U.S. regulators have yet to OK a booster dose for the general public, and that has become a point of contention for some public health experts. However, infectious-disease physicians have previously told MarketWatch that clinical decisions for COVID-19 booster shots should be based on data that’s available, not what’s projected to happen.
The agency defines a booster dose as one that “boosts” immunity from a vaccine’s “primary series” that has waned over time. “In a pandemic setting, it can be important to achieve high protection early with a second dose given at a shorter interval, however it may mean that a later dose for this boost effect is needed as well,” Oliver said. “This doesn’t necessarily mean that an annual booster dose would be needed.”BioNTech and Pfizer said last week that they had submitted data for a Comirnaty booster shot to the FDA.
