#asktheexperts hi mam ,my son is 4 year old , i have a question jo birth k time pe khasre ka tika lagta h uska mark nai h uspe hand p to kyaa Krna hoga

A. Mam these days the mark does not come and you don’t have to worry about it because once the vaccination is done it starts working but these days a lot of parents have the same query that the mark hasn’t come but it doesn’t come these days so need not worry about the vaccination is working from the time it has been given
