A member asked:

My daughter got the chicken pox vaccination. what are the chances she'll still get chicken pox?

A doctor has provided 1 answer

Possibly: Introduced in the late 70's in Japan, the current CPx vaccine was not adopted in the us until the 90's. There are good data that one dose removes the risk of death with cpx, but likely only 85% get protective immunity from 1 dose, with that improving to >95% after 2 doses given at least a month apart. Time will tell if future boosters are needed but with 30+ years of worldwide data it looks good
