The FDA authorized Pfizer and Moderna fourth doses for everyone age 50 and older, as well as a fifth dose for certain younger people with compromised immune systems.
People age 12 and older with weakened immune systems are eligible for a Pfizer 5th dose, and those 18 and older with the same condition are eligible for Moderna.
The Centers for Disease Control and Prevention quickly signed off on the decision, paving the way for those eligible to get a new round of boosters.
All of the new boosters are to be administered at least four months after the last shot.
“So is this the way it works? We talk endlessly about how we follow the science — it doesn’t seem to work out that way.”
An Israeli study from February among health-care workers ages 18 and older indicated that a fourth dose does not boost immunity but restores it to the peak strength of the third dose.
Many people in the study who received a fourth dose still got infected, though they were either asymptomatic or had mild symptoms.
