That wall of text is called an "argument"... those links are called "sources". This is how intelligent people converse. They don't just take pot-shots at each other... you make an argument backed up by evidence. It wouldn't hurt for you to try it.
It was _you_ who had the burden of proof BTW. I stated, with evidence, that vaccines are extremely effective. You have yet to show any evidence that they are not.
No - I don't think it's uniquely declining anywhere. I never said it wasn't! The vaccines definitely decline in efficacy over time. Since you refuse to back up anything you say - I have to infer that you're talking about the reports referenced here:
https://www.cidrap.umn.edu/news-per...ccine-protection-waning-against-infection-not
While it says that protection against infection dropped to 53% in nursing homes (which means the vaccine cut the "expected infections" in half) and 79% in the general population... these new reports still show a VE of 86% against hospitalization, which has been fairly steady. This once again shows that you were very wrong with your (unsubstantiated) claim of 40% of people in US hospitals for COVID are vaccinated.
Do you understand what 86% means? Covid has a case fatality rate between 1%-5% (
https://coronavirus.jhu.edu/data/mortality ). Even taking the bottom of that (1%) if everyone in the US got covid there would be 3.3M deaths. If everyone were vaccinated it would mean less than 462,000 people would die. That's a difference of nearly 3 _million_ people.
I don't understand how anti-vax people cannot see the enormity of a difference the vaccines can make. We've already lost over 635k people... we can drastically reduce the number still yet to die if everyone would get vaccinated!
BTW: it's not unusual for vaccines to require 3 doses... for instance, 3 doses were used for polio. Also: we all get boosters for vaccines all the time to make sure we maintain their effectiveness.
