I've been saying that since the vaccine was first released. It's common sense that when you give an anti-viral vaccine to people, there is a notable though not always significant chance that you can infect someone or at least pass on bits and pieces through things like breathing, intimate contact, and so one but that also depends on how the virus is transmitted and binding method anyway.
You know who else said this? All of the news networks for like a week after talk of a vaccine was getting serious. Then, magically, they all stopped.
On other social media sites, you would get straight up banned for saying any of this because they wanted a flying unicorn to give them their wishes instead of thinking, researching, and taking a more cautious approach.
So while the anti-vaxxers might be a bit crazy, the rabidly pro-vaxx crowd have actually done far far more damage by acting like they're bulletproof and spreading it to everyone including already vaxxed people and pumping out more variations than the anti-vaxx group (and the group who are still isolating - like me).
So, like I've said before, the only reason to get vaxxed is so you don't die if you get sick but it makes no difference if it's still spreading like crazy. Might as well just stay in lockdown until everyone else gets their heads straightened out.
I hope people are actually paying attention enough to start asking questions. The CDC director finally came out this morning and directly said fully vaccinated people can infect other fully vaccinated people, but everyone still needs to get the vaccine for some unknown and unexplained reason.
