At the ages of 11-12 years, how may shots does a child get and what are they?

Depends. Could be 5 depending on what they have already received. Tdap, definitely also called boostrix. Menactra, the meningitis vaccine, and Gardasil (hpv). And if child has not completed hepatitis a and received the 2nd varicella vaccine then it could be 5 but it usually is the first 3 i mentioned.
