Vaccination science is real. That's a separate issue from 1) what are they putting in the vaccines (adjuvants, preservatives, and such), 2) are those substances harmful, 3) is the mRNA shot even a vaccine, and 4) is it harmful to you?

I could add, 5) is it a good idea to bombard an infant with dozens of vaccinations which potentially involve some or all the issues listed above?

It's well established that exposure to Cow Pox will make you mildly ill, and confer immunity to Small Pox, which would have made you potentially deathly ill. That's the summation of authentic vaccine science in its simplest form. What goes under the name vaccine science today may or may not be that simple, and generally seems not to be.
