The vaccines don't prevent those things. They do lower the probability - or at least, that's the claim. That's not perfection, but it's not nothing, either.

As to whether the claim is accurate... that's outside the scope of this comment.

Who's claiming that? My impression is that official sources are now acknowledging it does nothing but lessen the chance of serious illness & hospitalisation for the person taking it.

Your impression is wrong, infection protection is still on the table.

That claim is pretty widespread and ubiquitous among the scientific literature. You might consider reassessing your news sources if they have been telling you otherwise.

I believe that the emphasis on the reduction of the chance of serious illness & hospitalization is because people believe that all the people who would be motivated to get vaccinated out of altruism are already vaccinated.

Pretty crazy how every single vaccinated person I know has tested positive for Covid since. I guess I and they must be outliers.

If there is some protection from spread, it's garbage protection.

That you anecdotally know vaccinated people who got Covid and that Covid vaccines lower the chance of being infected with Covid can both be true?

Yes, I knew I would get called out for an anecdote on this website. Thanks for not disappointing.

Perhaps you shouldn’t knowingly use flawed arguments if you don’t wish for the flaw to be called out

Meanwhile, among the many people I know who have been vaccinated, there's been just a single breakthrough case, and that case was due to catching covid from an unnvaccinated co-worker.

Since you seem a bit confused, here's what we know and don't know AFAIK:

1) Vaccination reduces your chance of getting infected. The efficacy depends on the strain of covid and the vaccine, but I have yet to see any science indicating that any vaccine has no efficacy against any strain.

2) Vaccination may or may not reduce your infectiousness while you are sick

3) Vaccination does reduce the average duration of infection, which means that while you may be as infectious as a non-vaccinated person while you are sick, you have a shorter window in which to spread that sickness.

So despite the unclearness of #2, we are very clearly able to say that vaccines reduce transmission because of #1 and #3.

Thanks for the assessment, but I'm not "confused" at all. Maybe if the pro-vaccine-mandate crowd wasn't so snide and insufferable people might take you more seriously.

Where do you see me advocating for vaccine mandates?

If there is a part of my comment you found snide, please let me know as that was not my intent.

That's not my impression. My impression is that official sources are claiming that it reduces the chances that you get it at all, and maybe reduces the chances that you'll pass it on as well.

I have never (that I recall) seen an official source saying what you claim. (Mind you, I'm not saying that you're wrong in your assessment of the effectiveness of the vaccine. I'm not even saying that you're wrong in your read of what officials are claiming - just that I have never seen it.)

Can you point me to someone official making that claim? And, what country are you in?

They lower your chance of getting covid by about 50% if exposed and lower your chance of spreading it if you get it by about 50%.

So.. It's not perfect at stopping transmission but you can see how it would definitely reduce the R0 enough to prevent outbreaks in the non-vaccinate pops.
