Klaatu, your counterpoint is spot on and well said. The analogy to CPU design and construction is well done. There is a lot of chemistry and physics involved that even I have a hard time following.

As a chemist, I am befuddled by some of my colleagues forgetting the scientific method and singling COVID-19 vaccination as either unimportant or a "conspiracy", as compared to the dozens of other vaccines we all have taken. I sure a heck do not what to return to the "good old days" of polio, smallpox, diphtheria, measles, tetanus, hepatitis A/B, flu/HIB, pertussis, mumps...and don't even get me started on chicken pox...
