You can give flu vaccine after 6 completed months....hepB and opv also come in 6,10 and 14 wks schedule....so ask ur pediatrician for it..

No. There must be at least 4 weeks gap between vaccine.

The gap between the vaccinations should be atleast 4 weeks... As you have finished the primary vaccinations nothing urgent is there for the 6th month vaccines... get it done after 1 month. PCV also should be taken.

No at least after 2 weeks

As per your shared vaccination schedule 1. Baby has received Hepatitis B at Bith & 1 month, so next dose can be given at 6 month of age. 2. OPV if missed can be given as per national schedule - at least 5 doses needed by 5 years of age....so you can give him OPV dose at 6 month or week earlier. 3. Also You child is not vaccinated for Pneumonia Conjucate Vaccine PCV...... Get him vaccinated at least 2 doses before 8 month & then booster at 15 month.
