In clinical practice, the pertussis vaccine commonly used is mostly the DTP (Diphtheria, Tetanus, and Pertussis) vaccine, which primarily includes diphtheria, pertussis (whooping cough), and tetanus. This vaccine effectively prevents these three infectious diseases. Common adverse reactions and side effects from the vaccine injection include local muscle site reactions such as redness, swelling, and hard lumps; if there is a secondary bacterial infection, it may also lead to purulent discharge. Additionally, some patients may experience transient fever symptoms, generally not lasting more than twenty-four hours, followed by common gastrointestinal reactions.
