These are people who don’t fit the specific criteria for being immunocompromised that would qualify them for a third dose of the vaccine. Some of them are over 65 but didn’t get their primary series with Pfizer. The majority got their shots at a pharmacy, not in a doctor’s office.

“We both have two Moderna shots and a Moderna booster, figuring that even if the booster isn’t approved yet, it can’t hurt,” said one source who is over 65 but not immunocompromised, speaking of himself and his wife. “Our family doc told us to get one ASAP.”

While sources didn’t share exactly how they got their Moderna “boosters,” the immunocompromised are only required to self-attest to their condition, and don’t need to bring a doctor’s note to their pharmacies in order to get third doses, according to the CDC.
