Coronavirus Pandemic Update 78: Mask Controversy; Vaccine Update for COVID-19 5

The CDC and WHO have conflicting recommendations on some aspects of the use of face coverings and masks, and Dr. Seheult reviews a NEJM article showing respiratory droplet spread with and without a mask. There are many COVID-19 vaccine trials in the works and "RAPS" appears to be a nice website to track vaccine progress.

If WHO wants to save masks for health care providers, they should say so. They're saying " if you're healthy you don't need to wear a mask", does not account for asymptomatic carriers who do not know they're healthy - and they know that. Lying to the people backfires when the people find out you are lying. They become skeptical of everything else you say.

Been following this since January and this is the only one I follow aside from Dr John Campbell. Kudos and stay safe and well

The pandamic"safety" measures(like social distancing, face masks, gloves, self-quarantine, etc) have NOT made people safe at all, at all. It just made people to be more racist & hateful to each other.

Best channel on Youtube. Am I the only one that would buy/wear a "MedCram Junkie" t-shirt if there was such a thing?

@MedCram. Saying from a thirld world country. If anyone in the world can afford an underwear they can afford a face mask (i.e., face cloth, DYI mask etc. NOT surgical or N95.)
Please, don't say WHO is not changing mask recommendation thinking about third world countries. They don't. If they would do, they wouldn't advice over and over for lockdown in these countries. People are dying here from starving during lockdown. They would have think of something useful for third world countries.
I appreciate CDC for quickly changing there recommendation on using face masks/cloth. But, WHO are just being stubborn to back up their all other wrong statements such as "no airborne transmission" and no long term immunity and others.

are we seriously STILL debating about masks 6 months in?

it's amazing how many scientists and virologists have come to write comments here

Regardless of what the CDC and WHO says, the evidence is absolutely and resoundingly clear that masks have played a huge part in the low number of cases and death in Asia especially in Taiwan and Hong Kong. And yet many people in the West still argue whether masks works. Just unbelievable...SMH.

What’s interesting about the NEJM study about masks was that the mask used was a slightly damp washcloth. Did they not do a comparison using a dry mask?

I love the "STAY HEALTHY" and very informative video, thank you as always.

Author — JellyBear6


@MedCram can you please make a video about people have symptoms over 2 to 3 months. Is it the virus stil in blood vessels or is it inflammation or is it auto immune.
Here's a group of such people .
And on reddit.
That's a group of atleast 3000 people, mostly young but still having symptoms. Would love to see your thoughts on it.

I wish I had half the energy you demonstrate. Thanks for all your work!

I would love to hear a detailed lecture into the specifics in vaccine testing and what it takes to reach completion.

i love all your videos and from the bottom of my heart thank you for doing them. the only problem i have, and have ever had with any of your videos is this part right here. the way he says "healthy" is different when wearing a mask, and not wearing a mask. i still believe we should be wearing masks yes. but i dont think he had to exaggerate during the demonstration. a real pity and shame.

I first saw that video several weeks ago, and it was enough to convince me to wear the damn thing. 🤮 Thanks for everything Doc, and Kyle. You guys have been a big help to those of us with family with risk factors.

If you wanna know how effective face masks are, just look at Taiwan. After all the misinformation and blatant lies the WHO and CDC have been spreading, I don't take their words seriously anymore

Great video as always. The visualizing droplets video was really interesting. The mask used was actually "a slightly damp washcloth over the speakers mouth." It would be interesting to see a test with dry and slightly damp cloth masks, along with the medical grade masks. On a different note It seems to me that we should be pumping up primary care to work up patients early on to determine those who are at risk to progress to serious disease (elevated D-dimer, IL markers, etc.) as well as having the opportunity to start the potentially useful antivirals before the storm. Thank you both for the tremendous service you are providing.

Masks are widely utilized in asian countries. I will wear a mask, considering that they have far more experience with these respiratory outbreaks. I can't say that WHO has my interest in mind.
