how well do the whooping cough vaccine work?

Very well: The vaccinated child is 27x less likely to develop whooping cough after exposure than those without. The protection is time related, months for infants & years for school age & adults; however, bacterial vaccines are never totally preventive in the face of heavy exposure. Death is most common <4-6m infants & essentially unheard of among the vaccinated.Boosters in adults protect infants.
