The information you so generously "shared" was not helpful. You intentionally spread it in a misleading way, and at this point enough counter-evidence has been provided to you that you must know you were wrong, which means you are now arguing in bad faith. Nowhere on that page does the CDC claim that current COVID-19 vaccines prevent the spread of the virus (in fact they explicitly disclaim the vaccine's effect on herd immunity), but you selectively quoted to make it seem as though they might have said that.
To be fair, a large portion of the blame lies with whoever wrote the copy for that CDC marketing page, as they are intentionally obscuring the fact that these vaccines do not prevent the spread of the virus. It's easily understandable why they are obscuring that fact and I suppose we should just be thankful that they haven't spread any outright lies on that page, again by explicitly making no claims about herd immunity. Note that the page does explain to people that they need to keep social distancing after receiving the vaccine, which shows that the CDC does acknowledge privately that the vaccine does not prevent transmission of the virus.
I haven't actually seen any convincing counter-evidence presented in a clear and concise manner. I've seen some stuff that gets off in the weeds, but ignores the mechanism of T-cell and B-cell mediated immunity and the most plausible mechanisms of transmission at an aggregate level, and that only focuses on primary outcomes of clinical trials, while ignoring secondary outcomes.
But I haven't seen anything that was written in a way that would convince a mildly skeptical human (and I've spent some time behind a micropipette) that vaccines do nothing to prevent contracting and spreading viruses in a meaningful (clinical - not analytical) sense.
I'm coming to this with an open mind, and I don't think I'm being a jerk about anything. I shared a quote from the CDC at face-value. You're just some faceless dude on the internet. Why should I believe you over the CDC?
"At the end of the process, our bodies have learned how to protect against future infection." <-- This is straight-up saying that the vaccine protects you from getting infected. I'm not quoting out of context or anything. If enough people are protected against getting infected, we reach herd immunity. Am I missing something here?
I promise I'm not masterminding some elaborate FUD campaign to undermine your premise. You're just saying something that's super-counterintuitive and then getting angry at me because I don't see clear evidence for it in what you presented.
You have seen the scientists writing explicit contrary to your claims, and even the specific vaccine testing protocols, I’ve given you the exact links and quotes, but you doubled down. The UK authorized Pfizer/BioNTech vaccine, and still:
svrb's comment is specifically with regard to vaccines: "They do not—and are not meant to—prevent people from contracting and spreading the virus."
What you acqq are posting is “Although the vaccine will give recipients immunity from the virus, scientists do not yet know whether it will stop them being carriers."
Can you see the very fine semantic line that is being walked here?
The public is being told by health officials that the virus gives 'immunity' from the virus. In the same breath, you are supporting the argument that it does nothing to prevent people from contracting and spreading the virus.
You guys are acting like this is all rather obvious, but it's not at all.
If I walked up to someone on the street and said that a vaccine will give them immunity, what do you think they would take that to mean?
Well, the NHS, and the CDC are both saying that the vaccine gives 'immunity' and 'protection.'
You have to stop getting angry at me, and consider that if you're not making a convincing argument to me, how the hell are you going to make a convincing argument to somebody who doesn't have a degree in biochemistry.
“Pfizer chairman Albert Bourla told Dateline host Lester Holt that the pharmaceutical company was “not certain” if the vaccine prevented the coronavirus from being transmitted, saying, “This is something that needs to be examined.””
