And your MD is from where??
Only people with medical doctorate degrees can understand anything to do with vaccination. In fact, I am too stupid to even read the packaging that my medical degreed doctor won’t show me, that says exactly what I dared in my utter ignorance to claim, that a given vaccine will not confer 100% immunity to each patient for the rest of their lives.
I will go on back to my life of blissful dumbnitude.
My allergist/immunologist told me the exact same thing.
They do not take with everyone and for many people they offer only partial immunity.
And what field is your MD in?
