Looks like the article is a little old. The article is saying that masks don't help when in fact, the thinking has changed since Feb 2020. Having a physical barrier between yourself and the outside world offers some protection from COVID. I ALWAYS double mask. Just want people out there to know that masking does help. I am fully vaccinated, but I double mask because I am concerned about variants. I don't want to be one of those "first cases" that show that the vaccine is not effective against variants. Wearing a masks helps protect you.
