pertussis vaccine

Pertussis, commonly known as whooping cough, is a highly contagious respiratory illness caused by the bacterium Bordetella pertussis. It is characterized by severe coughing fits, often followed by a distinctive "whoop" sound during inhalation, and can lead to vomiting and difficulty breathing. While it resembles a cold initially, it can be particularly dangerous for infants.123

The pertussis vaccine, often administered as part of the DTaP (diphtheria, tetanus, and acellular pertussis) vaccine, is crucial for preventing the disease. Introduced in the 1940s, whole-cell pertussis vaccines led to a significant decrease in cases. Acellular versions, developed later, are generally safer and are now standard. Immunization typically begins at two months of age, with booster shots recommended throughout childhood and adulthood to maintain immunity.243
