Q. A 2-month-old baby came for HBV. He recieved 1st dose of HBV and BCG at the time of birth and then DPT at 6 weeks. HBV was not given this time as it is not available at the PHC level. After 15 days, he was brought in for the 2nd dose of HBV. As far as I know, there should be a gap of 1 month between the two doses. Should we wait for 15 days and then give 2nd dose of DPT and HBV, or give HBV alone before completing 1 month?
