Interesting, but the sample size discussed is very very small - 204 households - and, as the researcher notes, there are many confounding variables to consider. To me, this does not at all suggest that a change of public policy is warranted at this time, but it would definitely be interesting to see more research.

Problem is that any source of data will have the same quality issues. Not alleging general propaganda, but I guess it always tends to confirm the initial suspicions of researchers as the data can be molded either way.

At this point it’s hard to see vaccine mandates (certainly without alternative options such as proof of recent infection/recovery or recent/regular negative test) as anything but punitive against the unvaccinated. (I am triple vaccinated, for the record)

My government is sadly too incompetent to get out of panic mode and now has evasion ideas like a central vaccination registers...

If this article is correct I hope that it will get incorporated into public policy swiftly.

Disregarding the correctness of its thesis article will be used by opponents of vaccinations.

This is completely anecdotal, but something interesting happened to me recently. My trainer, who is unvaccinated, got really sick one week. Lots of throwing up, high fever, headaches, just feeling awful in general. He tested negative for COVID multiple times. After his sickness went away, we worked out together (I'm vaccinated and boosted). Two days later, he calls me to tell me he tested positive for COVID but barel…

So one problem with thinking about vaccine protection from infection is that it’s hard to get data. In practice, when you see figures on protection against infection (typically these show limited though existent protection re omicron and significant protection re delta for boosted people) those figures are typically based on household infection. Which is kind of a worst case; constant exposure for days.

It may be that protection against infection by casual contact is significantly better, but it’s almost impossible to study that.

Earlier quoted context omitted.

Sure. But it's not a peer-reviewed Lancet paper. It's just one (well-qualified) person's opinion who disagrees with the current prevailing view held by other well-qualified people.

Is there a current prevailing expert opinion?

Current prevailing expert opinion is that vaccination reduces the chance of being infected by about 30-40% with Omicron, based on observational and case control studies.

Some studies see no signal of reduced transmission. Other areas see massive effects. It's all confounded because the vaccinated do not behave exactly like the unvaccinated.
