What do you mean by resistance? What's the point of vaccine if it doesn't increase immunity for you? I've only heard of vaccine resistance caused by the anti-vaxxers!
Are you saying, if enough of got the vaccine, we also shouldn't call that having herd immunity, but should call it herd resistance?
Anyway, my impression had always been that mRNA vaccines would prevent hospitalization 95% of the time. Even 1 does would give help us avoid hospitalization 60+% of the time. I was also assuming these shots would prevent death caused by Covid nearly 100% of the time... especially if the vaccines would help not strain the healthcare system.
If that story is true, not sure what's the main reason for cause of death... could be due to variant virus that rendered the vaccines ineffective... or perhaps the hospitals there are so strained that they just couldn't help him when complications arise...
Anyway, nowadays most people are anti-maskers. Shouldn't take long to find out how effective are our vaccines against variants.
