“You, like some of your fellow Americans, took an experimental treatment, not a vaccine.”
Treatment implies I was sick from Covid - I was not at the time of vaccination. I believe I’ve had Covid and had some level of natural immunity prior to vaccination.
They are vaccines because tens of millions of people have proven that they are.
They are considered under American law to be experimental. Sometimes it takes time for the US government to catch up with reality.
I think it's global, see Israel. Opened for the most part, using abominable vaccine passports but with infection and deaths still dropping. The opposite happened the two times they opened last year, and earlier this year.
But we will find out real effectiveness soon enough.
