So, you didn’t even bother to look up “Transfection” - it’s not a newly coined term or “a meaningless term meant to cause fear”.
https://en.wikipedia.org/wiki/Transfection
https://en.wikipedia.org/wiki/RNA_transfection
https://en.wikipedia.org/wiki/RNA_vaccine
From the J&J link:
“Johnson & Johnson: some protection from infection begins as early as 14 days after the shot, with full protection measured 28 days after the jab. That protection may get even better as time goes on, though, as zero COVID-19 cases were reported in patients who’d been vaccinated for 49 days or more.”
I don’t profess to understand it all, but your willful ignorance/derision makes me wonder if you should be giving advice on how safe something is or isn’t just because your screenname has an “MD” in it.
I see a lot of “may”’ in your work. The J and J vaccine is 60-65% effective i. clinical trials. Period And transfection is not a medical term. I’m sorry I didn’t go to the wikipedia school of medicine. Neither did I go to the google school of medicine.
