“,…one of the most dangerous challenges our world has faced in this lifetime.”
Misleading statement alert!
The few vaccinated people who still contract COVID-19 only get mildly ill so do not shed much virus. There are a very few vaccinated people who may be more strongly ill because the vaccine was not effective in their body - that’s a low risk probability.
But you are playing a ‘slide-by-…’ game of making a statement that sounds good but misleads by omitting probability.
As for ‘natural immunity’ there are two situations I am aware of:
- some people are immune from something in their past, such as a virus somewhat related to SARS2.
- an Israeli study used the term for people who have recovered from COVID-19, their research suggests they have greater immunity than they would have received from vaccine. Of course the study could not include people who died from COVID-19. People foolishly extrapolate that into a belief in not needing vaccine, which is not logical.
