This is extremely impressive research. I think if COVID has taught us anything though, even an array of available, safe, preventative medicine is not convincing for some people.
If only it worked for more than a few months at a time it might be worth it for more people. As of right now natural immunity is still much much better protection for those who have already recovered from COVID.
I am impressed at the amount and spread of disinformation. Absolutely amazing that world wide we have zero critical thinking skills at the population level. We allow ourselves to be controlled by a minority of very loud idiots.
This is not the case. The protection from vaccination is both higher and more consistent than natural infection with Covid-19. The very best immunity observed is in people who have been naturally infected and subsequently vaccinated (I don't think any studies yet out that have tested the other way around). Those people produced antibodies which showed strong in vitro activity against even highly mutated and apparently immuno-evasive mutants and against other known coronaviruses.
