> A Moderna booster is [a 1/2 dose of the regular Moderna shot.](https://www.fda.gov/media/153354/download) I can’t seem to find a cite, but my understanding is that a Pfizer booster is a full dose of the Pfizer vaccine, same as shots 1 & 2.

Yes.

But also, the regular Moderna shot had 100mcg of active ingredient, and the original Pfizer 30mcg. So the half-dose Moderna is still “more” than the Pfizer booster.
