where are the published peer reviewed clinical trials proving wearing masks prevents the spread of covid-19, or any virus for that matter?

They're on PubMed.
What the heck is "flouride" anyway?

Where are the peer reviewed clinical trials showing that parachutes work? There aren't any because it would be unethical to perform such studies. It is unethical to do a study that puts somebody at risk because on the known pathological transmission of a virus. You can't have a control group going around without masks and without social distancing. You can't have such people going around in high risk regions where governors mandate mask and social distancing and so not only would it be unethical to expose such people in such a way but it would also be illegal.
There has been observational epidemiological studies with regards to N95 mask wearing around COVID. The latest shows that healthcare workers wearing N95 masks were infected at a lower rate compared to the general population. That is proof that masks work. We know how the virus is transmitted and mitigating those factors with masks and social distancing is a common sense action to take based on epidemiological principles involving this respiratory virus.
There are laboratory studies of particulate spree reduction by mask wears and particulate filtration reducing infectious droplets.
There are epidemiological studies showing a reduction of transmission of the virus when mask wearing and social distancing is put into effect. We know it works.
The problem is people don't always want to wear masks and social distance. It was also politicized and so it makes things worse.

They are in scientific journals. Which are extensively indexed. If you don't know how to look them up, ask your librarian.

There is this thing, it's called common sense. Covid-19 is spread via infected respiratory droplets. A mask will keep your infected droplets to yourself, and to a lesser extent, keep you from breathing in infected droplets. The same common sense says if you stay six feet apart, you will not be in other people's airspace and sucking up their infected droplets. It doesn't really require a clinical trial.
Or are you one of those people that likes it when the government spends millions of dollars to determine that males and females are different??
