What age does whooping cough affect?

Whooping cough, or pertussis, primarily affects infants and young children, particularly those under the age of one, who are at the highest risk for severe complications. However, it can also affect older children, adolescents, and adults, especially if they have not been vaccinated or have not received booster shots. Vaccination is crucial for prevention, as the immunity provided by the vaccine can wane over time. It is important for pregnant women to be vaccinated to protect their newborns.
