Yes: Like strep throat, the whooping cough is a bacteria and you can get it more than once. Vaccinations we gave before the 90's had so many side effects, we didn't give boosters after 6 and teens/adults were the most often diagnosed group. Today's vaccine is milder and can be given to adults. The natural illness or vaccination produces only transient protection (up to a decade)
