Typhim vi how long does it last

Protection against hepatitis A lasts 1 year and protection against typhoid lasts 3 years. The vaccines work by stimulating your body to create antibodies infection-fighting proteins that prevent you getting ill if you become infected with the typhoid bacteria. As the Ty21a vaccine contains a live sample of Salmonella typhi bacteria, it isn't suitable for people with a weakened immune system — for example, people with HIV and those receiving certain types of treatment, such as chemotherapy.

It also isn't usually recommended for children under 5, whereas children can have the Vi vaccine from 2 years of age. It's unclear whether the Vi and Ty21a vaccines present a risk to pregnant or breastfeeding women. But vaccination should be considered if there's a significant risk of getting typhoid fever. The typhoid vaccine should ideally be given at least 1 month before you travel, although if necessary it can be given closer to your travel date.

Booster vaccinations are recommended every 3 years if you continue to be at risk of infection with typhoid bacteria. After having the typhoid fever vaccine, some people have temporary soreness, redness, swelling or hardness at the injection site.
