So your solution would be to vax everybody with TDaP every 2-3 years for the rest of their lives?
Read the comment I posted just under my comment to you about how overvaccination has led to resistant strains. Just like overuse of antibiotics.
No, I’m really not a proponent of vaccination, nor am I an anti-vaxxer. I was just pointing out the known, but not really well published, effective period of the vaccine. I think vaccine proponents do a horrible job of informing people about all the pros and cons of vaccination. And while I think it’s exceedingly horrible and sad, I’m not going to get worked up over 18 deaths per year and call for mandatory vaccinations like some people do.
