I politely suggest your post is misleading.It all depends on what science you want to believe.....
You appear to paint this as an issue where some scientists are pro-mask and pro-vaccines whereas others are not.
That is a gross distortion of the facts.
In reality, the overwhelming majority of qualified experts support the vaccines and the masks.
It, of course, suits the anti-vax camp to frame this as a situation where there are two sides, each with their own legitimate point of view.
This is not the case. Just look at the witches' brew of crazoid sources that the anti-vaxxers here are citing, for example. If this really was a disagreement between two legitimate camps, they would be able to cite mainstream sources for their anti-vax views.
