Transmissibility of SARS-CoV-2 among fully vaccinated individuals

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.<p>After his sickness went away, we worked out together (I&#x27;m vaccinated and boosted). Two days later, he calls me to tell me he tested positive for COVID but barely feels anything, just has a slight cough. He tested positive for a week and half afterwards.<p>I didn&#x27;t get sick whatsoever. I mean, maybe one day I had a little bit of nasal congestion, but it could have just been the cold weather or any number of things. My wife also did not get sick (but she&#x27;s vaccinated as well).<p>I think it&#x27;s too early to write off that vaccines don&#x27;t prevent transmissibility or even getting the virus. The immunization effects of these vaccines are so unknown to us given that they&#x27;re so new. This whole COVID-19 situation is so damn weird, and that&#x27;s why a lot of people are admittedly very skeptical of everything.

This isn&#x27;t a reviewed article, btw, but a &quot;correspondence&quot;, which per The Lancet: &quot;Correspondence letters are not usually peer reviewed (we rarely publish original research in this section)&quot;.

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.

This interesting article was posted earlier by another user and quickly received 28 upvotes but was flagged, presumably for editorializing the title. Reposted without the editorializing. A reply to this comment with a link to the unpaywalled pdf would obviously be helpful for many readers.

At this point it’s hard to see vaccine mandates (certainly without alternative options such as proof of recent infection&#x2F;recovery or recent&#x2F;regular negative test) as anything but punitive against the unvaccinated.<p>(I am triple vaccinated, for the record)

I&#x27;ve heard it mused that with Omicron, vaccination may further spread COVID19 in the sense that those vaccinated are less likely to feel sick (so don&#x27;t stay home from work&#x2F;avoid other people) but are just as likely to spread the virus.

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