Diphtheria is a life-threatening bacterial infection caused by Corynebacterium diphtheriae, which is transmitted through close physical and respiratory contact. The disease is characterized by symptoms such as laryngitis, pharyngitis, or tonsillitis, and a distinctive adherent membrane on the tonsils and pharynx. The diphtheria vaccine is crucial in preventing this serious illness, which has not been reported in Kenya for over 20 years due to effective immunization programs.
How the Diphtheria Vaccine Works
The diphtheria vaccine contains diphtheria toxoid, which stimulates the immune system to produce antibodies against the toxin produced by the bacteria. This vaccine is typically given as part of a combination vaccine, such as the DPT (Diphtheria, Pertussis, Tetanus) vaccine or the pentavalent vaccine, which also includes hepatitis B and Haemophilus influenzae type b (Hib) antigens.
