in some large countries such as the US if they have received the vaccine they are allowed to remove the mask.
I was a little surprised to read this news. I think the policy cannot be applied in all countries. do vaccines really make someone immune?

I think the policy is implemented so that vaccination can run quickly. if after receiving the vaccine it is allowed to remove the mask, the community will be happy to receive the vaccine. of course everyone knows that wearing a mask is something that is less fun

If vaccination is effective and will have no effect if you ignore health protocols including wearing a mask, in my opinion there is no problem if you are truly immune to Covid-19.
because I think we should keep wearing masks until everyone has a chance to get vaccinated and we have got the virus under control, and when community transmission is low and most people are vaccinated, I think we will be able to remove masks safely.
preferring to stick with masks or follow health protocols before infection rates become very low.
