So if I had not received the 3-shot series in childhood, the first shot of that series is the same as what they give for the booster? (In other words, if I go to ER and get a booster, and find out tomorrow that I didn't have the initial series in childhood, can I just follow up with 2 more shots?)
I'm still a little confused by your reply. The first shot in the initial series of 3 is the same thing (same strength, dose, etc.) as the booster? So if I get teh booster and find out I didn't have the initial 3 shot series, I will just followup with 2 more shots?
