Hi BCSnob,

I think this may be why it is still paused in USA. "“No final diagnosis”

AstraZeneca responded with a statement saying: “There is no final diagnosis and there will not be one until more tests are carried out.” However, NIH director Francis S. Collins, MD, PhD, seemed to give credence to the Times’ report when he told a Senate committee last week that the reason for the trial pause was a “spinal cord problem.”"

HEADS UP!!!! The youtube video was from March, 2020. We have learned a lot since then. Please post as current info as possible. Thank you.

Mod this video was made last month. Does that fit your criteria better?

This video shows how a mask handles a vape aerosol (many, many, many, many magnitudes larger than a CV virus or the water vapor it can hitch hike on).

Aerosol breath water vapor is much small and will hitch hike on air currents and float around for many minutes in a room.

It doesn't take much grey matter to see how good of a job a mask will do under these conditions.

AstraZenaca had a heavily decalled trials box van running around Chula Vista CA two weeks ago. They were enlisting volunteers taking nose swabs administering vaccine and they were administering different dosages. Compromised elders like me were given stronger doses. Then 2-4 weeks after an even stronger booster is to be administered, then a blood sample taken

The problem here is evaluation of information. In this day and age of the internet a huge amount of information is available and it is incumbent on us to evaluate that information. You can have a preconceived opinion and easily find supporting "evidence."

The key to using that gray matter and forming an informed opinion is to amass as much information and evaluate it according to it's veracity.

A study like BCSnob cited has way more validity than a youtube video of a doctor demonstrating expelling a huge tidal volume of vapor through various masks.

Nobody says masks are 100% effective in preventing spread of disease. In fact one of the reasons that masks were not originally recommended is that they may only have about 20% protective efficiency in filtering some droplets/aerosols.

What has been documented over and over by many studies is that use of masks combined with social distancing has some positive effect and is the most effective means we have at this time to reduce the spread of SARS-CoV-2.

To downplay their use because they don't provide 100% protection isn't using your gray matter to it's fullest potential.

I choose to believe this peer reviewed published study on the size of vape aerosol particle size (0.25-0.45 micrometer) over what is said in a YouTube video.

Electronic cigarette aerosol particle size distribution measurements

This size range is not larger the the droplets that carry exhaled viruses.

It doesn’t take much effort to fact check claims.

For reference aerosol particles are generally considered to be less than 5 micrometers while exhaled droplets are larger than 5 micrometers.
Particle sizes of infectious aerosols: implications for infection control

I recommended Google Scholar for finding (or “fact checking”) science information over many other sources including YouTube. The motto on google scholar is “ Stand on the shoulders of giants”.

Someone could make a analogous video on how seat belts don’t work; showing the injuries to belt wearers after accidents. It doesn’t prove seat belt use (or mask use) doesn’t reduce injuries and deaths. It only demonstrates that safety devices and safety measures are not binary in effectiveness.

What the vape/mask video didn’t have was the control; how much vapor would be blown at the camera when not wearing a mask (analogous to talking face to face with and without a mask).

You're exactly correct. You may have a preconceived opinion on this and don't even recognize it.

Here is a peer review study about gaiters from Duke

This is a peer review study that shows gaiters don't even work but are in fact, according to this peer review study more dangerous to wear.

I choose to believe peer review studies like this one.

BCSNOB are you a doctor like the guy on the YT video?

If not, your just some guy on a RV site giving your opinion. Nothing wrong with that. But it is what it it as they say.

No MD, just a lowly PhD working as a research scientist at a biotech company that is part of Operation Warp Speed (making covid antibody tests being recommended by NIAID for the phase III vaccine trials). What’s your expertise to be able to judge the non peer reviewed YT video?

I am aware of the differences in effectiveness of face coverings. If you’d bother reading the linked articles to assessed effectiveness you’ll find this has been discussed. I’m also aware that masks with exhaust valves offer little to no protection to those around the wearer. My employer’s mask policy is based upon the most up to date info on effectiveness of masks which is why we are not allowed to use gaiters, bandannas, and masks with exhaust valves.
