That was known all along, though.The Delta variant is a lot more infectious than anything we've experienced before. From memory (again, I'm too lazy to look it up -- you can if you want), estimates of the effectiveness of the Pfizer vaccine in preventing infection by the Delta variant range from 39% (Israeli study that I think just involved 20 or 30 people) up to 88%. The original Pfizer study, before the Delta variant arose, indicated the vaccine was 94% or 95% effective in preventing infection.
Why is this breaking news now?
I thought they had discovered that vaccinated people are more contagious than they had initially thought, which is why they are now issuing another mask mandate.
It was always known that the fully vaccinated could spread the virus a little bit.
So, now I'm confused wtf is going on. Why is the CDC telling people to wear masks now? Originally Posted by Strokey_McDingDong

Either way there's agreement that the vaccines are highly effective in preventing hospitalization and death.
I've been vaccinated and I'm not wearing a mask in most situations. Maybe I should be, I don't mind wearing one at all. But people around where I live look at you really weird when you mask up.
As to the claim that people who are vaccinated on average have higher viral loads when infected than the unvaccinated when infected, that sounds fishy. There are supposed to be some studies about to come out that may shed some light on that, according to the head of the CDC.
