The CDC believes that vaccinated people can spread the virus, which is why vaccinated people are being asked to mask up. They are not being asked to mask up because unvaccinated people could die. Unvaccinated people could die back in May too and no one really cared.
The data from the UK says that the death rate for Delta under age 50 is 0.02%. Less deadly than Alpha.
The unvaccinated are not making you have to mask up.
Just use your brain for 2 seconds, dude. LOL
