The pertussis vaccine is not an inactivated vaccine but a live attenuated vaccine, which primarily stimulates the body to produce antibodies. Once antibodies are produced, it can effectively prevent the disease pertussis. The commonly used pertussis vaccine in clinical settings is the trivalent vaccine, also known as the DTP vaccine, which can prevent pertussis, diphtheria, and tetanus—three infectious diseases caused by pathogens. It is essential to follow medical advice and complete the vaccination schedule as prescribed to achieve prevention. After vaccination, it is crucial to observe for any complications or adverse reactions.
