Not sure too many medical professionals would say that herd immunity is impossible. At some point we will achieve it. That is the point where there are not enough people without immunity to spread it. Now we may have to improve our immunity if variants evade that, but that is very different from saying we can't achieve herd immunity. This immunity is achieved by both vaccinations and infections, but it is achievable. And yes, people can still get it like the common cold, but if people are immune to the worst cases that counts too.
I do respect your opinions here too, but you are just flat out wrong saying there is no societal good for a 20-year-old getting vaccinated. It may not do much for THEM PERSONALLY, but are you saying that 20-year-olds never encounter 80-year-olds? That they wear their masks religiously to prevent spread to unvaccinated or vaccinated other people? Of course they don't. More people will die if everyone under 30 did not get vaccinated. That is a fact. Everyone is too selfish in this country.
The Ontario study does NOT say that the vaccines have no effect either. 37%>0%. And those numbers are being revised. Facts are important. This whole conversation (which I appreciate the civility) is about how many people die from the vaccine when stupid athletes like John Stockton suggest it is a lot. Show me where that number is even more than 1,000 in the U.S.? That study just does not exist because people are believing things that are not true, included various misrepresented studies like that Ontario one and several of the Israeli studies (there was an early one that implied people that had COVID were better protected than vaccinated people and that has been debunked with better data).
There is just no significant risk in taking the vaccine. None. And even when there are side effects one of the vaccines is better at eliminating those side effects to provide an option for most people. I am all for allowing medical exemptions. But those exemptions need to be reality-based and not hearsay-based.
