No, we’ve been told that the mRNA vaccines are, based on the current evidence, both “ highly effective against hospitalization and death for a variety of strains, including Alpha (B.1.1.7), Beta (B.1.351), Gamma (P.1), and Delta (B.1.617.2)” and that they make the vaccinated “less likely than unvaccinated persons to acquire SARS-CoV-2 or to transmit it to others”, though they have “lower effectiveness against confirmed infection and symptomatic disease caused by the Beta, Gamma, and Delta variants compared with the ancestral strain and Alpha variant.”

When we get data that contradicts what we expect, it needs to be taken seriously, it needs to be broadcast, it needs to be followed up on, and the correct conclusions need to be drawn from experts in a transparent way.
Sure.
> If 69% of people are vaccinated, I would expect <69% of recent COVID cases to be from the vaccinated.
I would expect both vaccination and detection of cases to overrepresent people with better access to and inclination toward medical services
In addition vaccinations are biased towards the elderly, and (because vaccines haven't been approved, even on an emergency basis, for this population) completely exclude young children. This also biases the figures.
Basically, the media reporting of “contradictory” findings is pretty much completely abuse of statistics rather than actual contradictory findings.
A decent discussion is here: https://english.elpais.com/usa/2021-07-27/covid-19-infection...
That said, I don’t think the data from the OP’s CDC article is a case of Simpson’s paradox. The quoted statistic in the CDC article is that 74% of infected people were vaccinated. I am comparing that to the vaccination rate in MA of 69% (also from the article). The denominator in one stat is a strict subset of the denominator of the second stat. Simpson’s paradox requires disjoint denominators.
So that being the case, I would still like for actual experts to follow up on this data and come to some conclusion.
If less people have covid, less severely, for less time, that is less mutation potential.
My understanding is that changes to the spike protein significant enough to escape vaccines entirely are likely to also render it unable to enter the cell.
