Can your child get the chicken pox after their vaccination by being exposed to another child with them?

In brief: Yes, it's possible

It is possible for this to happen, since the chicken pox (i.
e., varicella) vaccine is not 100% effective. The vaccine increases the probability of not being infected with the chicken pox virus, but it is not an absolute guarantee. However, a child without the vaccine will almost certainly become infected if exposed (because the virus is so virulent), but the child with the vaccine probably won't.

Back when only 1 dose of chicken pox was recommended we used to see a lot of cases of very mild chickenpox in immunized children, with very tiny lesions and no scarring. Now that 2 doses are recommended we hardly ever see that, too.

In brief: Definitely

The first chickenpox vaccine given at 12 months old gives 95% protection, there is a 5% chance that your child will still get the chickenpox, but in a very mild form.That is why they need a second dose(booster) between 4-6 years old to give them 99.
99999% protection.
