Chicken pox vaccine and siblings

[Anne8888]

I’ve booked the chickenpox vaccine for my 5 year old as there has been cases in school. We have a 7 month old baby and I’m worried about 5 year old developing a rash from the vaccine and potentially infecting the baby - has this ever happened with anyone?

Your baby is probably more likely catch it from your school child and their friends than from the vaccine.
