I'm pretty sure we haven't seen any study that says everyone should go out and get infected as a way to reduce spread.
I'm also pretty sure we haven't seen any study or development on a way to quantify a person's unique prior infection (or assumed infection) to know how their specific infection compares to the standard vaccine dose. Certainly not one that's easier or cheaper than just getting vaccinated with the standard dose.
All of the studies we've seen point to getting vaccinated offers additional protection beyond whatever condition someone had prior to vaccination.
- Someone who has never had COVID is better off after vaccination than they were before. At least for a time, and then they probably need another dose, up to at least 3 so far.
- Someone who has had 1 or 2 vaccine doses is better off with an additional dose, up to at least 3 so far.
- Someone who previously had COVID is better off after a vaccination dose than they were before.
It's kind of like an all expense paid free trip to WDW.
- Someone who has never been to WDW will enjoy an all expense paid free trip to WDW.
- Someone who has been to WDW just once will enjoy an all expense paid free trip to WDW.
- Someone who has been to WDW many times will enjoy an all expense paid free trip to WDW.
What I'm saying is: Will someone please give me an all expense paid free trip to WDW?
