" the vaccines don't reliably prevent infection or transmission. "

I think his is actually misleading.

The vaccines significantly reduce transmission overall - mostly due to the fact people are much less likely to get COVID in the first place if they are vaccinated.

Where you can maybe have a point, is that people who are vaccinated - who do get COVID - may transmit it at the same rate as those who were unvaccinated and infected. Maybe.

But this is a secondary effect to the first order issue, which is that vaccines significantly reduce infections in the first place, and therefore reduces R0.

Yes, cloth masks are marginal, but they are at least 'another layer' of protection.
