Pertussis vaccination has been VERY effective at eliminating the strain that’s in the vaccine.
It has NOT eliminated all the pertussis strains however.
My generation was ‘saved’ from a version of pertussis. Now we are susceptible to a strain with TEN TIMES the mortality and morbidity of the one we would have gotten in childhood.
No vaccine covers this new strain.
It’s the wild wild west all over again with the new version.
Try for a strain that’s got 100X the mortality and morbidity of the old one?
You eliminate the ‘mild’ one and set yourself up for the really really bad one.
Let me repeat. But if you weren’t given the pertussis vac as you suggest, we might not be having discussion right now. Right?
Same thing with polio, etc.
