I've received multiple shots of mRNA "vaccines". I can't unreceive them. I'm doomed to whatever fate the shots have damned me.
Oh, well. I made an educated decision based upon the information at the time - die now of Covid-19/SARS2 on a respirator in a hospital ICU, or risk swollen magnetic tetsticles and the unknown. I chose to live then to die later. If I chose to die then, I would not have been able to live later.
I made an imperfect decision during imperfect times - which is pretty much what living is about.
If vaccines were bull$h!t, the Earth's population would not be over 7 Billion people ... small pox, polio, measles, scarlet fever, influenza, etc. would have thinned the human herd to a smaller number.
Vaccines can be safe. Vaccines can be effective. Vaccines can be imperfect, but a World afflicted with disease is far less perfect.
The anti-vaxxers have the luxury of eschewing vaccines because those vaccines have been so effective at eliminating, reducing, or containing diseases that would have killed the anti-vaxxers before they reached adulthood. In short, it is previous generations' intelligent decisions to eliminate disease that enable their descendants to be nitwit anti-vaxxers.
For past generations, living was a luxury and stupidity was fatal. Today, living is a probability and stupidity is a luxury.
