Although the vaccines included in the National Immunization Schedule of India have not changed, there are some modifications in the immunization schedule. This article will describe the revisions.
The National Immunization Schedule is a schedule of vaccines that are offered as part of the Universal Immunization Program (UIP). In addition to the names of vaccines, it describes the timing, dose, route of administration, site of administration, and diluents used to reconstitute the vaccines.
The following vaccine preventable diseases are covered under the Universal Immunization Program:
- Hepatitis B
- Japanese Encephalitis
- Pneumococcal disease
- Haemophilus influenza type B related illnesses
- Diarrhoea caused by Rotavirus
The updated National Immunization Schedule now includes information on the maximum age for administration of specific vaccines.
A fully immunized child should have received
By 1 year age
- 3 doses of OPV,
- 3 doses of Rotavirus (where applicable),
- 3 doses of Pentavalent,
- 3 doses of PCV (where applicable),
- 2 doses of fractional IPV,
- MR vacccine -1st dose ,
- JE 1st dose (where applicable)
By 2 years age (in addition to the above)
- MR vaccine – 2nd dose,
- JE 2nd dose (where applicable),
- DPT booster, and
- Polio booster
Immunization Schedule for Pregnant women:
The second dose of TT/ TT Booster dose is supposed to be administered before 36 weeks of pregnancy. However, it may be administered even after 36 weeks have lapsed (if the woman has not received it by then).
If a woman has previously not been immunized with TT and comes in labour, she must be administered a dose of TT during labour.
Immunization Schedule for Infants:
Pentavalent vaccine (containing Diphtheria+Pertussis+Tetanus+Hepatitis B+Hib) has replaced the separate DPT and Hepatitis B vaccines administered at 6, 10, and 14 weeks respectively.
Both Oral Polio Vaccine (OPV) and Inactivated Polio Vaccine (IPV) are administered as part of the National Immunization Schedule. While OPV continues to be administered at birth (0 dose), then at 6, 10, and 14 weeks; IPV is administered at 6 and 14 weeks. In due course, OPV will be phased out completely, and only IPV will be administered (either as a standalone vaccine, or as part of a multivalent vaccine).
Immunization Schedule for Children:
In Kerala, the Measles vaccine between 9-12 months has been replaced with Measles/Rubella (MR) vaccine as mentioned above. However, instead of the second dose of MR vaccine between 16-24 months, children receive the Measles/Mumps/Rubella (MMR) vaccine (this was being administered even before the MR vaccine was introduced).
The National Immunization Schedule by age of recipient/duration of pregnancy:
TT-1: Preferably at the first visit, or as early as possible
TT-2: Four weeks after TT-1, or preferably before 36 weeks of gestation
TT booster: For women who have received TT-2 within the last 3 years
Infants and Children:

6 weeks: OPV-1, Fractional IPV, Pentavalent, Rotavirus (where applicable), PCV (where applicable)
10 weeks: OPV-2, Pentavalent, Rotavirus (where applicable)
14 weeks: OPV-3, Fractional IPV, Pentavalent, Rotavirus (where applicable), PCV (where applicable)
9 completed months: PCV Booster (where applicable), Vitamin A (1st dose)
9-12 months: MR 1st dose, Japanese Encephalitis 1st dose
16-24 months: MR 2nd dose, DPT Booster-1, Japanese Encephalitis 2nd dose, OPV Booster
