The Typhoid Fever Vaccine is designed to protect against typhoid fever, a serious illness caused by the bacterium Salmonella typhi. This vaccine is especially important for travelers to areas where the disease is common, as well as for individuals in high-risk environments. There are two main types of vaccines: the inactivated (injectable) vaccine and the live attenuated (oral) vaccine. Both types stimulate the immune system to recognize and fight the Salmonella typhi bacteria, reducing the risk of infection and severe illness. Vaccination is a key preventive measure in controlling the spread of typhoid fever.
