Is it possible to get whooping cough as an adult if you had an immunization as a child dry cough, lungs hurt, slight fever

Yes. : Yes. Immunity wanes after a few years so you need a booster every 8-10 years. You may just have a viral bronchitis but if cough persists you should see your doctor for an evaluation. You should also get a pertussis booster ( tdap).

Yes: Yes you can get pertussis or whooping cough . Get yourself checked

Very much so: The old whole cell whooping cough vaccine has so many side effects it was never given after age 6 & by their teen years, many became vulnerable.For years teens were our largest group of new cases. The new acellular pertussis vaccine became available in the mid 1990's but was not in wide use in older teens or adults until after 2000. No vaccine within 10 years=vulnerable.
