Hi my son, age 1 year 4 months need to take vaccine between 15 to 18 months so I have following queries which are cited below 1: is it necessary to take vaccine during this covid-19 pandemic 2: if yes then whether 2 vaccines can be take at a time and whether any side effects may be arise due to taking plenty of vaccine at a single go 3: what sorts of safety precautions can be taken to protect my son against covid risk as he is only 1.4 months old baby when we take him to outside for vaccination.
