Calling a vaccine a belief, diminishing it to a personal preference, is a deadly one.
Well, the fact of the matter is that it (taking the vaccine) IS a personal preference. THAT is a fact.
I have taken both injections of the Pfizer vaccine and plan to take the booster in December. That is my preference, just as it may be someone else's preference to not take the vaccines.
Unless you advocate jailing those who prefer not to vaccinate.
