COVID has leapt from the realm of science and reason into fear and hysteria.
If we 'saved' 1 million elderly people from dying of COVID, and they instead died over a period of time from vaccine side effects, those effects would be impossible to quantify via a binary PCR test and so would be ignored.
Additionally if people were vaccinated, but still died, we could at least say 'oh well, we tried'.
Rushing out a vaccine and giving it to people near the end of their natural lives is a completely legitimate decision to end this hysteria and get back to normal life.
