Masks need to be changed frequently to work. Even the top of the line masks need to be cleaned by UV machines for reuse if they are not replaced frequently. I have a couple of the N95 masks, but wear the cheap disposal ones on a daily basis changing them during the day now as masks are required where I work.
I've read different data about the length of time coronavirus particles can hover around in the air. Dependent on the size of the particulate, it can be as long as 15 minutes according to a few studies (as I recall without notes). So, I keep this in mind while out and about with "empty" elevators I will still take a pass if stairs are empty. Even then, a person could have released the virus in the hallway and the person long gone...the airborne virus lingers.
The jury is still undecided about whether or not these available vaccines reduce transmission. I haven't found anything to prove it does. There is proof that the opposite is happening now with the Delta variant, that vaccinated status formerly touted as a preventative, soon became not a preventative but reduces likelihood of complications. The only thing it's shown to do is reduce severity in cases.
Why did the US (NIH) pull the funding on Novavax's safer vaccine do you think? The Novavax product is more like the traditional vaccines, a sub unit method less riskier by far compared to mRNA proven by various studies. "The company has faced consistent FDA approval delays which have led to a dip in NVAX stock." Sounds like the good ole' FDA is not a fan of Novavax...I can see why they are hoping to knock it off the playing field in the US. It's going to be utilized in other countries, and the US is at the mercy of the FDA's power play delaying their testing to block it.

The mRNA method...training cells to produce protein spikes that could break off. They are hopeful not many of these created protein spikes break off and they certainly are hoping they don't wind up in organs. Using fat to hold it together is the issue. That still blows my mind. They do not know how long the fatty substance holds together, according to pro-vaccine researchers interviewed, and they don't know exactly which muscles are taking in the protein, just "muscle tissue". It varies from how it was described and depends upon an individual's unique response.
I don't like unknowns when it comes to health measures, particularly untested methods (we cannot even know at this point how long antibodies work from natural immunity versus immunity from the jabs). Reportedly (this will evolve over time) antibodies were found 5-6 months out after natural exposure. Then, as time allowed, it was 7-8 months soon moving to more saying 8 months best estimate. Now? We need more time to elapse. Most likely, in two months testing will show antibodies at 10 months...12 months...you see where I am going here. Best (longest) immune response is from natural immunity, working with B (memory cells), and T "cleaner uppers".
Interesting that CDC is holding off on "approving" boosters, drug companies are biting at the bit to make this a never ending thing. Unscrupulous drug company heads hope that more people begin to believe that our strong immune systems, able to fight off 4 other coronviruses (novel 5th type making it currently radicalized as far as reactions) has just gone to pot. We are all instantly at the mercy of the drug czars (a select group it seems, some aren't allowed by FDA), and their determination that our immune systems, which have enabled mankind to live through all kinds of tragic events, are now null and void Why should I believe that a novel coronavirus with low risk for me (healthy, no meds needed, no existing problems) with wipe out my immune system so I suddenly need to rely on vaccines for the rest of my life to stay well? They NIH, CDC, Fauci/NIIAAD, FDA, government involved officials (gave the okay to rush the vaccines with companies that had never produced a vaccine before) are hoping more come to believe we are doomed without annual injections, multiple injections.
After major factor that's influenced my decision to not accept one of the untested jabs: Merck & Co., one of the top US producers of vaccines failed its own line of a C-19 vaccine. Their assessment? "
There is no evidence that a vaccine will be superior to natural immunity". That is a statement, made by one of the top leading vaccine producers of all time in the US and why they didn't proceed. Their tests showed that a vaccine route was not superior to a no-vaccine route. Perhaps Merck did not want to go through a repeat of having a whistleblower and the claim Merck exaggerated protective quality for mumps vaccine during trials. Interesting that is was reported this past June, 5 Indian drug makers are testing Merck's failed vaccine...the same failed product according to Merck's own testing. Wow...desperate measures it would seem.

Okay, so I'll apologize for the inconsistent train of thought to the above paragraphs. Your post brought up many good points, but there is a lot more I'd like to share/run by you/compare notes.
