Is it okay to get these 3 doses now, 1) if we will get these 3 doses in 30 days next dose when will we take, 45 days after taking 3 doses or 45 days off from birth. 2) if we will take only BCG & OPV 30 th day and missing Hep B at birth time Is there any problem to have missed 1 St dose of Hep B vaccine at birth time Is it okay to go with a 6th week dose and when will we take a 6th week dose. 45 days After BCG & OPV taken or 45 days after birth. Could you please provide me with proper explanation
