If mom had chickenpox then how long it will take to affect the my child and if my chickenpox clears out and I give shot to my child then there are how many % chances my child will be infected

A. If your child is close to you or in your connection most of the times then within 3 to 5 days a person can catch chickenpox who has never had and if it’s your child doesn’t get it and once you start to heal or get better after that you can get the vaccination done immediately there is no problem
