CDC updates guidance, recommends vaccinated people wear masks indoors in certain areas

Doesn't make a difference if vaccinated people can transmit the virus as easily as unvaccinated people.

I was just pointing out that cancer patients can get the vaccine and 90% can develop the antibodies.

But they can't spread it as easily. The exact degree of protection against infection varies by study, but they all agree that being vaccinated substantially reduces the risk of infection and therefore of transmitting it to someone else.

You certainly seemed to be arguing that cancer patients get just as much protection from vaccines as others, which seems not to be the case (see the leaked CDC slide deck for more studies). Vaccinating me really does protect others, even if the others are also vaccinated.

Exactly some people can't seem to understand that.

No I did not, I am not an idiot like your trying to make out. I know what a vaccine is and it's not magic like your trying to say. Of course you can still get sick and spread it, but you won't up in the hospital or a grave. You want to die, have at it I am sick of the deniers and anti vaxxers, I'm out.

I asked for a source of your claim that vaccinated people spread the virus x5 less than unvaccinated people.

What we're finding from delta is that those who are infected and vaccinated can spread the virus as much as the infected an unvaccinated.

Where have we found that? All studies show that the vaccinated are substantially less likely to be infected than the unvaccinated, and I'm not aware of any studies that estimate how likely infected people in the two classes are to transmit the virus. Virus may well be more localized in the vaccinated, and is much more likely to be neutralized (and therefore noninfectious) by antibodies. We simply do not know at this point how much transmission is occurring from the vaccinated.

On the question of infection rate with delta for the vaccinated, there's a new study here from the UK, which has administered roughly equal amounts of AZ and Pfizer vaccines. They report: 'Using self-reported vaccination status, we estimated adjusted vaccine
effectiveness against infection in round 13 of 49% (22%, 67%) among participants aged 18
to 64 years, which rose to 58% (33%, 73%) when considering only strong positives (Cycle
threshold [Ct] values < 27)'.
