First masks didn't work, then they did, then they didn't...........now you gotta wear 2.
What a clown.
Dr. Anthony Fauci, President Biden’s chief medical adviser on COVID-19, said two face masks are likely more effective than one against the novel coronavirus, despite significant uncertainty on the subject.

In all fairness to Dr. Fauci, the right way to confront the pandemic is a work in progress.
No one really knows how to handle it.
Ideas come and go.
So it does seem common sense to say that two masks are more effective than one mask.
But nobody really knows at this point.
And I guess that three masks would be more effective than two masks.
In one or two years from now, we will learn that "science" was right on some points and wrong on other points (even terribly wrong?).
