Pfizer COVID vaccine

It would have been impossible to predict the efficiency of the COVID vaccination program at the newly-opened Fort Washington Armory location. It was amazing. Including the seat wiper.
Some ingenious pharmacists have figured out how to get a sixth dose out of the "fill" in Pfizer's vaccine. Pfizer wants those magically-found "extra doses" counted towards its commitment to the U.S. government. And the company wants to be paid for what it's providing.
After Pfizer's COVID vaccine was administered in the UK, two allergic reactions surfaced. Who’s to blame? The drug maker? I argue no. Pfizer could not possibly have known in advance whether these reactions would occur or, if so, how frequently. Why's that? Here's why.
We have two great vaccines so far. One has to be kept in a regular freezer; the other in a mega freezer. This is because they contain RNA, which is unstable, not the more-stable DNA. What sense does this make? For the answer, you'll need to navigate The Dreaded Chemistry Lesson From Hell! Enjoy. Hint: It's one lousy oxygen atom.
