It's the opinion of a medical professional, not some random guy who submitted his thoughts to an editorial page.
Given the state of our fake news MSM, i prefer to get my news directly from people who know what they are talking about, not someone who will edit and omit the things they don't agree with.
You sound like you only trust information that journalists feed us. That's rather scary.
Mayo Clinic: “Can face masks help slow the spread of the virus that causes coronavirus disease 2019 (COVID-19)? Yes. Face masks combined with other preventive measures, such as getting vaccinated, frequent hand-washing and physical distancing, can help slow the spread of the virus that causes COVID-19.”

What is added by this report?
Consistent use of a face mask or respirator in indoor public settings was associated with lower odds of a positive SARS-CoV-2 test result (adjusted odds ratio = 0.44). Use of respirators with higher filtration capacity was associated with the most protection, compared with no mask use.“
https://www.cdc.gov/mmwr/volumes/71/wr/mm7106e1.htmJohns Hopkins Medicine, from Lisa Lockerd Maragakis, M.D., M.P.H.: “ Can wearing a face mask prevent coronavirus from spreading?
Yes. Since the coronavirus can spread through droplets and particles released into the air by speaking, singing, coughing or sneezing, masks are very helpful to prevent the virus from spreading in crowded indoor public places, especially those that contain a mixture of vaccinated and unvaccinated individuals.
Cloth Masks
In non-health care settings, multiple-layer fabric cloth masks are excellent barriers for containing respiratory droplets and interrupting viral transmission if they are worn consistently and properly, covering the nose and mouth.“

I’m not saying you do this, FJ, but I’m amazed by how people will latch on to one source and ignore hundreds of others… because the one conforms to their political beliefs the hundreds don’t.
Person A: “This one doctor on bitchute/rumble/truth social with no background in immunology or infectious diseases, who also happens to be selling a book and/or miracle cure, says the vaccine makes you magnetic!” (DISCLAIMER: I haven’t actually seen anybody on this forum say that; I’m trying to illustrate a thought process. Although, I haven’t read through all 496 pages of this thread…)
Person B: “Sure, but hundreds, if not thousands, of doctors who have studied infectious diseases and vaccines for years, from prestigious medical schools and public health organizations throughout the world, say that’s not possible, and there are no documented cases of it actually happening.”
Person B: “Fake news! I can’t believe you believe those quacks!”
