Diphtheria
The TDAP vaccine provides protection against diphtheria, a highly prevalent disease during the 1920s before the development of the vaccine. In the United States alone, approximately 15,000 children and teenagers were infected every year. However, with the introduction of the diphtheria vaccine in the 1940s, the disease was virtually eradicated in the country. Despite this, outbreaks still occur frequently in various parts of the world, and the number of cases tends to vary based on the rates of immunization.
Pertussis: The Highly Contagious Whooping Cough
Pertussis, also known as whooping cough, is a highly contagious respiratory disease that primarily affects infants and young children. This infectious condition is characterized by an intense, uncontrollable cough, which can result in severe respiratory distress, apnea, pneumonia, and even death. It is crucial for adults to receive vaccination against pertussis, despite the likelihood of experiencing milder symptoms, to prevent transmission to vulnerable children.
