Q: My son is 1 year old and is taking his immunisations as per the schedule. However, since the local Early Childhood Centre is open only during the 1st week of every month, he is taking his immunisation 2 weeks in advance. The nurse at the clinic says it is alright. However, a family friend said that it is not good. Please advise.

A:You have not indicated the vaccination that is due for the child now. However, as a general rule it may be preferable to delay the immunisation by two weeks rather than give it two weeks before the due date. Sometimes premature immunisation leads to improper uptake of the vaccine (may not be protective optimally).
