vaccines aren't really meant to prevent people from contracting the virus they have been designed against. This has been true forever. You've been told this dozens of times already, yet you persist in pretending that isn't true. I don't really know why you keep doing this.
Hepatitis B vaccine. This is a terrible disease that affects millions of poor people especially in Southeast Asia but could easily be prevented if they had easy access to the vaccine at birth. Are you saying Hepatitis B vaccine doesn't prevent you from contracting the B virus? Because I'm pretty sure if you are vaccinated, you're protected from contracting Hepatitis B.
Polio. Another terrible disease. Same as Hepatitis B. If you're vaccinated against polio, you're pretty much protected from this awful disease.
When we first got Pfizer and Moderna covid vaccine, we were told it would prevent hospitalization and death. Awesome. They also said while it won't 100% prevent you from still contracting covid, breakthrough cases should be somewhat limited and rare as the covid vaccine provides good protection from you catching covid. Great. Give me the vaccine.
And I think for alpha and somewhat for delta, the above was true. But for omicron, I think the current world data makes it pretty clear the vaccine won't prevent you from contracting covid. But I'm going to give the vaccine the benefit of the doubt that it's still protecting the vaccinated person from hospitalization and death. Which is why I'm fully vaccinated with boosters along with my wife and my daughter.
However, omicron is proving to be so contagious that even masks don't seem to help much as I mentioned above about South Korea. So if that's the case, why wear mask if I'm fully vaccinated? Especially if omicron cases are on the decline in the US.
