Can an adult catch whooping cough if they had it as a childAsk us anything?

Yes, an adult can catch whooping cough (pertussis) even if they had it as a child. Immunity from the disease or vaccination can wane over time, making individuals susceptible to reinfection. Additionally, the vaccine's effectiveness decreases over the years, which is why booster shots are recommended for adults, especially those in close contact with infants.
