WHY SHOULD YOU GET a VACCINATED FOR TYPHOID

...

An incidence of typhoid can cost approximately 35% of the average monthly household income6,7

...

Since typhoid cases are treated with antimicrobials, a resistance is developed and thus, prevention by vaccine is of utmost importance8

Vaccination is the most effective way to prevent typhoid and minimise it’s treatment cost

vaccines available

Polysaccharide vaccines (PSV)

have been available for many years, yet a large population remains at higher risk due to the low efficacy of these vaccines, requirement for multiple doses, and restrictive age limit for those below 2 years

Typhoid conjugate vaccines (TCV)

are more efficacious than the previously available polysaccharide vaccines 9,10

Provides long lasting protection

Can be administered to childrenabove 6 months of age

Requires one dose and effective for more than 2 years

Has higher efficacy along with immune memory

TCV is a cost-saving strategy in urban India

WHO SHOULD GET a VACCINATED FOR TYPHOID?
Dose Initiation

ACVIP and WHO recommend TCV from 6 months onwards 11

Vaccine naïve population

It is believed that typhoid vaccine is only for kids aged 6 months. However, any individual above 6 months of age if not vaccinated against typhoid should be vaccinated

Previously vaccinated with polysaccharide vaccine

The new age typhoid vaccines (Typhoid Conjugate Vaccines) are once-in-a-lifetime vaccine that provides long-term protection
