Beloved, 
5. Disposable surgical face masks: a systematic review
I wish above all things that thou mayest... be in health...
3 John 1:2
Two randomized controlled trials were included involving a total of 1453 patients. In a small trial there was a trend towards masks being associated with fewer infections, whereas in a large trial there was no difference in infection rates between the masked and unmasked group.

Q: WHY does Pelosi herself not follow the ACTUAL SCIENCE on the Topic?
Q: WHY is the word "science" treated like a god by these people?
"After declaring that House GOP minority leader Kevin McCarthy
was a “moron” for saying he opposes the new mask mandate (even for fully
vaccinated people), Nancy Pelosi just repeated the word “science” over
and over again as justification.
When a reporter asked “Is Kevin McCarthy a moron, and if so, why?” Pelosi responded “I said earlier in my comment, science, science, science, and science.”
“On almost every subject that you can name, science is the answer,” Pelosi added, without actually giving any scientific explanation as to why vaccinated people have to wear masks that do not protect them or other people against anything.
“Whether it’s the climate
crisis, whether it’s a health crisis, whether it’s our preeminence in
the world and technology, science, science, science, science,” Pelosi bizarrely barked." ZeroHedge
Words from the mouth of the wise are gracious, but fools are consumed by their own lips.
