Anyone here have whooping cough before?

Supposedly it's a cough so bad that you can't control it to the point where you can break your ribs, and projectile vomit, and potentially scar your lungs.

The vaccine for it is the Tdap vaccine, and after four years it only has 35% efficacy against the disease.. so after 5 years you probably have no protection.

How bad is it in adults?
