I was thinking that if the vaccines worked with the Delta (say the same rate as the original COVID) then the vaccinated wouldn't need to wear masks. Ideally there'd be no death increase because majority of people are vaccinated.
I've yet to see anything that says that vaccines may not work because of X. It's highly one-sided to talk about things that challenge the vaccines effectiveness (as in even to apply critical thinking) because every resource online, on news, from experts, and social media are censored, belittled as misinformation, or disregarded. It makes it a win-win situation for vaccinated side and not because of science.
I have seen multiple articles pointing out that vaccination doesn't prevent infection. I have also seen multiple articles expressing concern about other variants becoming resistant to the vaccines. This is a situation that changes frequently because new variants are *expected* to arise and spread if there are enough people not resistant.
This is basic epidemiology.
On the other hand, the current vaccines *do* work to prevent hospitalization and death, even from the delta variant. Whether that will be true for the lambda variant is yet to be seen. We can't tell until we have the data.
As for low probability side effects, the probability *is* a relevant factor in assessing risk. The probability of long term problems or death from the virus is far, far larger than the probability of harmful side effects of the vaccine. And so the risk assessment is that the vaccine is preferable to getting the virus *even with the side effects*.
It simply isn't a dichotomy between working/not working. WHAT does the vaccine help prevent and what does it not? How do we mitigate the things the vaccine does NOT prevent?
Masks are required because the vaccine does NOT prevent infection or spread. The vaccine DOES help to prevent hospitalization and death.
