Younger folks are certainly circulating more. And I’m familiar with a few that had it and healed.
I’m ambivalent about the elders getting vaccinated. It’s a different matter, however, for those that fall into the 0.015% category — mainly the young. Furthermore, I’m not saying the vax doesn’t prevent the SARS symptoms.
It is a pleasure to have reasonable debate. I tend to be against vaccination for the youth. In due course they will fight it off. I am also of the opinion that natural immunity is the real thing, gets to T cell (memory) and that if you have had it you are good to go and need not to be vaccinated.
In my judgment, a tiered approach should be used and it seems to be what is happening. I think that anyone over 65 should be vaccinated regardless of health status. I think anyone over 40 with comorbidities should be vaccinated or with high exposure (health care workers for example).
I think if you are under 40 and in good shape — not being vaccinated is a very reasonable choice. The risks and benefits are about the same for this age group.
I am also of the opinion that the delta variant is far more contagious and spreads more rapidly, while being less severe. This is exactly what should happen in a pandemic. Lots of people in the middle part of this pandemic compared this to the Spanish flu of 1917. That came in three waves. I think this is the third wave, that will run its course more rapidly, and hopefully with many vaccinations being given, will accelerate the speed of the wave because there are just not as many placed for the virus to take hold.
This third more contagious wave + natural immunity + vaccine immunity should equal true herd immunity.
