Under the IAP recommended immunization schedule, typhoid conjugate vaccine (TCV) is administered as:

• A Two doses at 9 and 16 to 18 months
• B Three doses at 6, 10 and 14 weeks along with pentavalent vaccine
• C Single dose only after 2 years of age
• D Single dose at 9 to 12 months of age, which can be co-administered with MR vaccine ✓

Explanation

Typhoid conjugate vaccine is recommended by IAP as a single dose between 9 and 12 months, conveniently co-administered with the measles-rubella vaccine at the 9-month visit, since both are injectable vaccines given at separate sites. The polysaccharide typhoid vaccines were unsuitable below 2 years, but conjugation made TCV immunogenic in infancy, which is exactly why option C is outdated. TCV is not part of the Universal Immunization Programme routine schedule.
