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
