hi doctor ,my son is one year old now, yet he is not t aken, influenza, typhoid, MR1 vaccines, how much gap between 2 vaccines? when should give these vaccines?

A. it is important to maintain a gap of at least one month or around 4 weeks between any n two vaccination dates which are given. the doctor may give multiple vaccines at the s ame time on the same day. but the next group of vaccines should be given only after a delay of 4 weeks for proper immunity development
