Yes, you are right — for most routine vaccines, a minimum gap of about 4 weeks is usually recommended between doses, especially when multiple injectable vaccines are involved. This helps the immune system respond optimally.
However, the Polio Day (Pulse Polio) vaccine is an exception.
The oral polio vaccine given on Polio Day is safe to give even if your child has recently received other vaccines or is scheduled to receive them soon. This special drive is done for community protection, not just individual protection. The goal is to replace any possible wild polio virus in the community with a harmless vaccine virus, thereby preventing the disease from spreading.
So, even if your child has received routine immunisations recently, giving the Polio Day drops at the same time is safe and recommended.
