Typhoid vaccine is a vaccine used to prevent typhoid, a disease caused by Salmonella typhi bacteria, which is often transmitted through contaminated food or water. The vaccine stimulates the immune system to produce antibodies capable of fighting the bacteria and protecting the body from infection. Typhoid vaccine is recommended for people traveling to areas where the disease is common, as well as for those working in areas exposed to contamination, to ensure health and prevention.
It also significantly reduces the risk of infection and alleviates the severity of symptoms if infection occurs. Typhoid vaccine can be administered either by injection or orally, depending on the type of vaccine used. The recommended dosage schedule must be adhered to for maximum effectiveness, making it one of the primary means of preventing typhoid, especially in endemic areas.
