I'm aware there is data about severity of cases in individuals, but I haven't seen good data showing the impact to community transmission.
I'm trying to remember if our herd immunity artcle covered the monitoring stats ratios between vaccinated and unvaccinated. I'm thinking that the lead author left it out
The incidence rate ratios of COVID-19 are impacted by vaccination status.

> All incidence and hospitalization rate ratios exceeded 1, regardless of predominant variant, indicating that the risks were consistently highest for unvaccinated persons and that COVID-19 vaccines were protective against SARS-CoV-2 infection and COVID-19–associated hospitalization among fully vaccinated persons, and most protective among those with a booster.

This one shows a nice breakdown of the incidence rate ratio among age groups and similar.
------------
What does this have to do with community transmission?
[1] If you aren't infected, you aren't spreading the disease
[2] A lower transmission rate equates to lower community spread all else equal (as someone identified earlier, Jevon's paradox could come to head)
[3] The lower IRR is a lower propensity (or, if you prefer, a lower R_t) between the two groups.
-----------
This matches what I see in my regional reporting; the IRR is significantly different between the two groups. In my area (a red state in the US) behaviors are mostly back to pre-pandemic levels of behavior, so it is reasonable to conclude that the IRR in my area is representative of life following any COVID-19 protocols being relaxed.
A reduction in the incidence rate ratio among vaccinated individuals is a reduction to community spread, ceterus paribus.
Have a good evening.
I don't believe you do and I shouldn't need to either way. "Believe me bro" isn't science.

What's that supposed to mean? What reason, what explanation?
> and pointed you to the appropriate resources.
You pointed to no appropriate resources. You actually deflected from the question and provided a lot of links and waffle that did not answer the question at all. In case it wasn't clear, I was not asking for techbro handwaving about whether vaccines impact community transmission. I was asking for actual data.
> A reduction in the incidence rate ratio among vaccinated individuals is a reduction to community spread.
An assertion that you have failed to prove and have no evidence for, as far as I can see.
> Have a good evening.
You too. And try not to make any more claims you don't have evidence for, it's misinformation.
I'll respond here in case your engagement with disinformation caused anyone confusion.
> "Believe me bro" isn't science.
Correct. This is a public internet forum where private or restricted access sources are not shareable, not an open science conference. Hence the reason the Washington State and CDC studies were shared, which align to claims made.
> What's that supposed to mean? What reason, what explanation?
I'll refer you to prior comments in this discussion chain.

Read the links provided.

Tautologies generally don't need proof. I believe you're being intentionally deceptive here.
Why tautological: a reduction in an individual's capacity to become infected with the virus reduces their individual capacity to spread the disease. A community is a collection of individuals; reducing many people's capacity through a vaccine to spread disease reduces community spread.
I refer you to both the Washington State study as well as the CDC study for the recent incidence rate ratio comparison between vaccinated and unvaccinated populations.

It's comments like these that show you are sealioning. Strong evidence for your questions have been provided in this comment: https://news.ycombinator.com/item?id=30232957 -- your inability to acknowledge the evidence provided because it disproves your attempt at sowing confusion doesn't mean the evidence is not clearly presented and available.
Versus sealioning on a controversial topic -- that's disinformation. I find insulting when people engage in it, and I'll not entertain your comments further.
--------------------
For any reading this comment chain who may be confused -- vaccinations reduce community spread, the evidence has been provided in the comment linked, and I encourage you to strongly distrust when people are "just asking questions."
You can't just cry "sealioning" after you make unsubstantiated claims and refuse to provide evidence for them.
> Correct. This is a public internet forum where private or restricted access sources are not shareable, not an open science conference.
Very convenient you just brought that up only after several back and forth posts that showed you were unable to substantiate your claim with actual data. You can see why I don't believe you.
> For any reading this comment chain who may be confused -- vaccinations reduce community spread, the evidence has been provided in the comment linked, and I encourage you to strongly distrust when people are "just asking questions."
Evidence was not provided. If evidence was provided, then you wouldn't be talking about these non-public sources of evidence you claim to be privy to, would you? They would be irrelevant because you would be able to just provide the evidence.
Your story has fallen apart badly. It's clearly pointless to keep beating a dead horse here and obviously you're not the type to ever admit they're wrong. Just keep it in mind for next time and stop yourself from spreading misinformation.
