I do wonder though about vaccines lowering symptoms and ‘disguising’ infection, thus potentially promoting spread

By the way: do you have links/references to those studies about the «correlation between spread and vaccination rates»?

:) (If we could smile over these phenomena.) Do you have suggestions about good news and commentary sources in your area?

I must note: the question about whether the vaccinated could have more asymptomatic cases is a very interesting intellectual proposal. In a way, factored by other effects (such as a reduced infection rate) it could be embedded in a measure of the complexive rates of being infective of the vaccinated. Policy wise though, it could be very relevant if the unvaccinated showed less symptoms.
I looked at that. If you assume that people in different areas behave in the same way with respect to social contact, even if they behave in different ways wrt. vaccination, then it supports your conclusion. The study tries to average that out, but...
There are studies that don't have this weakness. For example, you may look at households, on the assumption that people will have so much social contact with their households that the differences don't matter. Here's one that looks at that. "We estimated vaccine effectiveness against onward transmission by comparing secondary attack rates among household members between vaccinated and unvaccinated index cases, based on source and contact tracing data collected when Delta variant was dominant." https://www.medrxiv.org/content/10.1101/2021.10.14.21264959v... I've seen another study with comparable results (the error bars overlapped).
