What type of immunity is given by typhoid?

Typhoid fever confers acquired immunity, primarily through the body's adaptive immune response. After infection with the Salmonella Typhi bacteria, the immune system produces specific antibodies and memory cells that provide protection against future infections. Vaccination against typhoid can also induce a similar immune response, offering some level of immunity. However, this immunity may wane over time, necessitating booster doses for continued protection.
