People age 50 and older now are eligible to get a second COVID-19 booster, following authorization by federal regulators on Tuesday. But the action poses a tricky question for millions of Americans: Should they get that fourth shot — and when?
booster, following authorization by federal regulators on Tuesday. But the action poses a tricky question for millions of Americans: Should they get that fourth shot — and when?
“Current evidence suggests some waning of protection over time against serious outcomes from COVID-19 in older and immunocompromised individuals,” Dr. Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research, said in a statement explaining the FDA’s action. He noted that a second booster “could help increase protection levels for these higher-risk individuals.”
In its decision, the FDA, which typically authorizes vaccines after hearing expert testimony before an advisory panel, skipped that panel in greenlighting a fourth dose for older adults and fifth dose, or third booster, for people whose immune system is compromised by a conditions that reduce the effectiveness of the vaccine, such as an organ transplant or cancer.
On Monday, Dr. Bob Wachter, UCSF’s chief of medicine, posted a question on Twitter that he said was typical of those he’s been asked lately: “I'm over 50, had my 3 shots, AND had Covid in past 3 months. Should I get 2nd booster?”
