Can You Get Your Flu Shot and COVID Booster in the Same Arm? - Lifehacker

It was a new vaccine, after all, so they recommended waiting two weeks before or after getting any other vaccine, including a flue shot.

The CDC recommends using separate arms if you are getting a COVID shot and a high-dose or adjuvanted flu shot.

Separating shots by a few weeks is sometimes recommended for the monkeypox vaccine, for example, although if you know you’ve been exposed to monkeypox you should not delay getting the vaccine.

Most of the time, if you’re getting two shots, providers will assume that you would like to get them in separate arms.

You can also dodge the question entirely by scheduling your flu and COVID shots for different days, which is convenient enough if you’re getting them at a neighborhood pharmacy.
