The typhoid vaccine is designed to protect against typhoid fever, a serious illness caused by the bacterium Salmonella typhi. There are two main types of vaccines: the inactivated (killed) vaccine, which is given as an injection, and the live attenuated vaccine, which is taken orally. Both vaccines help the body develop immunity to the bacteria. Vaccination is especially important for people traveling to areas where typhoid fever is common. The vaccine is recommended for individuals at higher risk, such as those living in or visiting regions with poor sanitation and hygiene. Regular vaccination can significantly reduce the incidence of this preventable disease.
