Are the 3 year old booster vaccines, which now include chicken pox, one or two injections? So I can prepare my child as best as possible! Thanks.

This suggests just 1 vaccine that combines 4 things - MMRV

Two vaccines, one in each arm.
MMRV and Dip, tet, whooping cough, polio.

Oops, yes you're correct @DemonsandMosquitoes . I didnt read the first line and thought it was all one vaccine. I thought it didnt seem much as my own kids had more than one at that age
