I may be remembering wrong, but I clearly remember everyone saying that the Moderna vaccine only needs 1 shot and people were talking about how that's going to affect vaccination lines and people wanting which, etc. But now I check and I see that the moderna vaccine also needs 2 shots. When did this change happen or am I just remembering wrong? (ie they've always said it was two doses from the beginning). Im just curious cause I clearly remember in the beginning that Moderna was a one dose, when did the change happen if at all I don't remember hearing anything about it (or at least it wasn't as big of a news as the annoucements of the vaccines).
