I thought a little about what you said. To be honest, I wasn't basing my definition of full immunity on a dictionary. Even though English is my second language lol. I was basing it on my lived experience, as the expression goes. I grew up in Africa and the Middle East and I was subjected to a LOT of vaccinations. More than you folks in the West. Heck, maybe we were the guinea pigs 😒 In fact, most of my "smart" cousins are doctors who advocate vaccines because that's what you study in college when you are smart 🙄 And there's that whole pesky thing about ridding the world of small pox thanks to vaccinations. Anyways, point well-taken.  The point I was making is the REVERSAL of logic whereby to be protected by a vaccine, first you need other people to be vaccinated. It used to be vaccines protect you from other people, infectious or not. Hence the debasement of language. QED. 

 Heard and appreciated. Our lived experiences shape our worldviews. My belief is by speaking with others we all grow from it. Truly 😊
