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.
You’d be surprised at the number of people who want mandatory vaccination for every vaccine for every person on an ongoing basis ever 3-5 years.
My objection is simple. Any time you ‘control’ a disease by selecting this or that particular strain for elimination you simply select for all the rest of the strains preferentially. Resistant strains will outrun you every single time.
