Can you have Dr. Z tell this to Dr. Offit next time he sees him? They are still masking at CHOP for certain symptoms and you see the staff largely masking. We go to a CHOP satellite office for primary care and it annoys me. I know there will always be some who mask from now on, but we can try to at least combat bad policy! For the record I did mask when we didn't (or I didn't) know better but I was a skeptic. It would be great if we could get this messaging out by someone most will believe
I know what you mean. MY GP's office @ St Mary's Med Bldg has a sign on the door that you cannot enter unless wearing a mask. On the sliding glass window, one of the practice Dr's has a typed up list that you need a mask & vaccination card (Who asks for this anymore??). I want to scream every time I'm in that office.
I love my Dr otherwise I would. She's a good GP and has an excellent NP which are so hard to find. Thankfully, I don't see the other Dr. who requires proof of vaccination.
Are you saying it makes no sense to wear a mssk in public indoors if one is very vulnerable to URIs? I have long Covid and it is Hell. A curse. It sucks--the life out of you.
Yes, The evidence is overwhelming. Unless you are wearing a P100 respirator fitted for you or a brand new, N95 mask fitted for you (and that only for an hour or so) masking is valueless. Multiple studies in ORs where comparative OR staffs were masked and unmasked -- no difference in patient nor provider outcomes. This was the lie that begat all the rest.
Why are all people who make mistakes liars? Are all doctors who make mistaken diagnoses and engage in practices that lack evidence liars? Are all doctors and others who wear masks in the OR fools and liars? So much demonization going around. To err is human, not evil. Are you always right?
Because they knew they were lying. On February 20 Fauci sent a memo to a personal friend (cited here https://brownstone.org/articles/when-fauci-told-the-truth-about-masking/) that noted that masking would not be effective so not to bother. He was muscled the next weekend and all of a sudden was talking about two masks. No new knowledge came to the fore. Call it whatever you like -- he knew the literature said that masking had no value.
If the open surgical field and the mass of people wandering around coughing and cutting and whatever in the OR in close proximity to the gaping surgical wound do not show any difference, it is highly unlikely that your walking quickly past someone with a piece of cloth over your face makes any difference either.
I know you would love to believe masking works and it seems it should. But the virions are literally 1/1000 the size of the holes in the mask fabric. The fact is that it has long been known that masking is ineffective except as a psychic prop to make people feel better. If it makes you feel better, go for it...no harm unless you are going to rob a bank as Vinay points out.
Your sources are impeccable but also irrelevant for the Peter Swenson’s of the world, who are making emotional rather than intellectual decisions. That’s interesting psychologically, but otherwise I don’t have any more insights.
What remains a fundamental mystery is why Fauci, etc, flipped on masking and everything else he knew. He did it very convincingly so it is at least possible he really believed it. But still, something happened in a few days to make him start sounding insane.
Thank you. I did not know all this, and about Fauci. I had heard of his prevarications about CDC gain of function research funding in Wuhan. I too would like to know why he flipped.
Mask wearing was very widespread across the globe. Up to 80-90% (95% in Spain, 91% in Italy for example according to one study). I think it implausible that Fauci caused that. Or that Spanish and Italian "liars" brought that about. Can we assume that they were all listening to/obeying Fauci? I don't know. Perhaps they thought it would help and thought better to try to save lives--the precautionary principle. They didn't know it wouldn't. Possibly didn't check the research and should have. I don't know. I just would rather not impute base motives like deception (for political, economic, ego reasons?) across the board inside as well as outside the US.
Yes, I am emotional about this issue, because I am vulnerable and I have seen people die of Covid. I'm in misery because of long Covid. But not irrational and uninquisitive. And I'm tired of the current right-wing demonization of the US public health responders to Covid. There was overreach and it had many causes. Maybe the road to hell is paved wiith good intentions. But good intentions do not always lead to hell. But indeed, the consequences can be terrible--e.g, the election of our un-American wannabe Putin by irrational MAGAites and MAHAites.
Masks do not provide any benefit whatsoever and are probably unhealthy, as they trap bacteria. They will also isolate you socially, which is harmful emotionally.
The people who recommended or demanded masks be worn did it for some other reason than your health, probably their ego.
I don't understand why trapping my own bacteria from my own lungs makes a difference, even over a long period of time. Please explain, maybe you're right, but I've never heard this. I don't mind being socially isolated in a public space where nobody knows me I don't care to be known--just want to go about my private business. I find people quite friendly to me when I'm wearing a mask, and I reciprocate, and feel unharmed emotionally.
"Probably their ego"? You paint with a very fat brush. Many individuals have multiple motives, and they don't necessarily overlap with others' motives. Many of "the people" who recommended masks maybe thought, mistakenly perhaps, that lives would be saved--I find that altruistic, not egoistic. I prefer a pointilist painting of the heterogeneity of people, their widely varying knowledge, thoughts, motives, and--righteousness, arrogance, and--beliefs in their superior intelligence. And delusions of significance.
I have read the study. A possibility, yes, but a slim one. Also, it begins by saying millions of lives were saved by the vaccines. Only a tiny number get post-vax syndrome. Correct me if I'm wrong. So, therefore, what.....?
I think Vinay went over this in another substack, but it's unlikely anyone's life was saved by the vaccines unfortunately.
Unless you got both vaccines and Covid around the same time, I would assume, that you know whether long-covid onset came after a vaccine or Covid itself?
I would be interested in reading what he wrote on vaccines and how he came to that conclusion.
I've read that there have been significant excess deaths in red states, possibly because of negative attitudes about vaccination, etc., and fewer mandates. I don't know how good the research is or could be given methodological problems.
Mandates unfortunately forced healthy people to vaccinate. They were never at risk of death to begin with. COVID was a disease of the elderly and people w comorbities w obesity being a standout. Alot of healthy people along with children suffered vaccine injury due to those mandates.
Red states are poorer, more obese and diabetic (esp in the deep South), and in some cases have larger elderly retired populations (e.g. Florida). All these demographic factors are known to be powerful predictors of COVID severity. And yet there are also certain red states like ND which fared very well in terms of cumulative COVID mortality. In that case, low population density is probably explanatory (and high density places like NYC which otherwise supported strict mandates had comparatively high mortality). I am fairly certain that if you compare pre- and post-vax mortality, you'll see the same variations. The demographic factors explain a great deal.
I'm pretty sure Vinay debunked the "red-states are having more deaths because they won't vaccinate" theory more than a year ago. What Matt Hawthorn said - if you don't find comparable obesity rates, diabetes rates, and other health issues pre-covid, the Covid death rates won't be comparable either.
He's saying that the studies show no benefit overall to the entire community masking - that it doesn't stop community spread, and that cloth masks are particularly ineffective, and that because of this, there shouldn't be mandates. Certainly not for populations like kids in schools where there are real negatives to learning.
There could be a lot of reasons for this - during the pandemic, for example, it could be that most spread was between families, so public masking wasn't addressing the majority of spread. It could be that a lot of people cracked open the windows, and that those who didn't were sitting in closed rooms for hours where a mask couldn't prevent anything anyways.
Personally, I feel like if you're sick and you're coughing and you've decided to go out (wish people wouldn't, but maybe they need food or medicine), a mask is more effective than "covering your cough" with your arm. Sometimes Vinay will observe people wearing masks, comment on it in his Substacks ("why are they still doing this?") and doesn't seem to acknowledge that these studies weren't testing particular situations like "masking by sick people reduces transmission".
Thanks. I'm just worried about getting infected again and making things worse. Even if my mask is only partially effective, why not? Why regard me as stupid, Vinay? I know I famous cardiologist in a certain big city in Massachusetts who has had long Covid for 3+ years. He masks in public. I listen to him. Akiko Iwasaki, the celebrated, supposedly brilliant Yale immunologist and long Covid expert always masks--knowing how devastating long Covid is to people lives.
DOJ needs to be aware of confounders such as sheltering in place causing lost wages pushing study subject into life of crime with mask! Who otherwise may never had become a data point in this retrospective review.
Prasad; a thousand thanks. I thought I was alone with this concern.
(1): In Spring of 2020; I passed a man with handkerchief mask and hat and sunglasses. No part of his face/head was visible. He could have been a metal robot.
(2): In Summer 2020; I was standing on the sidewalk waiting for light to turn green. Next to me was a masked stranger that I didn’t recognize. Two minutes later; we both jumped in shock. The “stranger” was my supervisor whom I saw in the office daily. She hadn’t recognized me at first, either.
(3): Facial recognition deters many from antisocial behavior. When faces become obscured during a societal emergency- the “recognition as deterrent” component decreases in effect. Therefore, a number of people would be expected to engage in more frequent or more severe antisocial behavior. Therefore, increased cooperation with police is necessary. But, we did the opposite by combining obscured identity with less police cooperation in 2020 during the George Floyd riots.
(4): In my neighborhood, you can see which people are the drug-dealers because they wear Covid masks.
(5): I have been very frustrated by city/state/federal officials who failed to publicly declare that the mask phase of Covid epidemic was over.
(6): For a comparison, is cooperation with law enforcement less or greater in Muslim countries where have the population has concealed faces?
Talk about cherry picking Vinay. Most of you posts are great but you seem to follow some talking points of certain ideological groups.
Here's a quick review from Chat GPT
Recent studies have provided substantial evidence supporting the effectiveness of masks in reducing the transmission of respiratory viruses:
Comprehensive Review (2024): An extensive review published in Clinical Microbiology Reviews analyzed over 400 studies across various disciplines. The findings strongly indicate that masks and respirators are effective in mitigating the spread of respiratory infections, including COVID-19.
Cochrane Review (2023): A Cochrane review evaluated randomized controlled trials and cluster trials on interventions aimed at reducing respiratory virus spread. The analysis highlighted the importance of understanding study conditions when interpreting findings related to mask efficacy.
Modeling Study (2021): Research utilizing computational models demonstrated that combining universal mask-wearing with physical distancing of at least one meter can reduce exposure to airborne pathogens by over 99%. This significant reduction underscores the critical role of masks in controlling virus transmission.
The Cochrane Review did NOT conclude that masks worked, most especially cloth and surgical. Please read again what Chat GPT said, or didn’t say, in its response.
I believe Vinay and maybe Tracy Beth Hoag possibly wrote about masking studies and broke them down in detail a couple of years ago?
Vinay stated: "the evidence was clear that community mask wearing did not slow the spread of respiratory viruses". The Cochrane Review concluded that the evidence was insufficient to prove either way, and certainly did not conclude that they don't work. If you look at some of these studies they are pretty hopeless. Most of us believe that a properly fitted surgical mask most probably prevents spread of infection, assuming other measures such as hand washing and separation will reduce transmission. It appears like common sense, I doubt we'll see surgical masks abandoned in theatre. Without a properly designed and controlled trial to determine this we have to rely on common sense. When in the early stages of a pandemic and prior to a vaccine it is best to rely on common sense when clinical trials are inadequate to exclude the expected benefit. Reminds me of the NEJM 'study' pointing out that there was no reliable evidence that using a parachute was any safer when jumping out of a plane than not using a parachute.
Some studies are pretty hopeless. Definitely agree on that. Remember that there was a lot of pushback on Tom Jefferson’s conclusions in the Cochrane review. Vinay has explained in detail why community masking doesn’t work in other articles. In addition, I’m sure you’re aware that masking in the healthcare arena was originally designed as a way to protect against blood borne pathogens, not respiratory viruses. Once again I recommend the not cherry picked, paper by Vinay and others that reviewed many mask studies, analyzed methodology, and concluded that cloth and surgical masks are not effective at reducing spread of respiratory viruses, among other conclusions that so many of the mask studies have been deeply flawed. In addition, I recommend a study be done on the long term effects of mask wearing on the immune system. Also the issue is community masking, emphasis on community, which introduces all sorts of issues.
I agree with most of your comments. However having looked at some of those studies, they just aren't performed well enough to tell us if a properly fitted surgical mask ?N95 in combination with other measures. In the middle of an epidemic killing thousands of people and in the absence of reliable data, we just have to rely on common sense. The freedom fighters from MAGA and the US are rather ridiculous carrying on as if it is a massive issue, when in fact following an aggressive vaccination program would have saved hundreds of thousands of lives. They were inconvenienced for a while whilst many people died unecessarily.
Despite being made aware, multiple times, along with many others in the guv, the "department of JUSTICE" , doesn't see anything wrong with a Swiss pharmaceutical company ripping off medicare for billions with useless so called drugs.

Why are you still going there? Maybe it’s time to find another office.
I love my Dr otherwise I would. She's a good GP and has an excellent NP which are so hard to find. Thankfully, I don't see the other Dr. who requires proof of vaccination.
OK. I misunderstood your comment.
Vaccination card?!? Good grief!!!
Lol, IKR???
Absolutely insane!!
The biggest crime produced by mask is Fauci’s.
Are you saying it makes no sense to wear a mssk in public indoors if one is very vulnerable to URIs? I have long Covid and it is Hell. A curse. It sucks--the life out of you.
Yes, The evidence is overwhelming. Unless you are wearing a P100 respirator fitted for you or a brand new, N95 mask fitted for you (and that only for an hour or so) masking is valueless.

Don’t shoot the messenger…
I don’t think Dr. K deserves this type of comment.
Why talk about a "lie"? The people advocating masking were not "lying." I know many who are decent, honest, and sincere. Please explain; I'll listen.
Because they knew they were lying. On February 20 Fauci sent a memo to a personal friend (cited here https://brownstone.org/articles/when-fauci-told-the-truth-about-masking/) that noted that masking would not be effective so not to bother. He was muscled the next weekend and all of a sudden was talking about two masks. No new knowledge came to the fore. Call it whatever you like -- he knew the literature said that masking had no value.
There are literally 100s of papers on the unefficacy of masks. There have only been about a dozen quasi-RCTs on masking and none of them show value. https://le.utah.gov/publicweb/BRISCJK/PublicWeb/43178/43178.html
The OR studies one of the other respondents mentioned are summarized here. https://monashhealth.org/wp-content/uploads/2019/03/MasksSurgery_Evidence-Snapshot2016.pdf
If the open surgical field and the mass of people wandering around coughing and cutting and whatever in the OR in close proximity to the gaping surgical wound do not show any difference, it is highly unlikely that your walking quickly past someone with a piece of cloth over your face makes any difference either.
Cochrane is likely the best source of unbiased data on medical topics in dispute. They looked at it extensively three times over a couple decades. The conclusions are always the same: https://brownstone.org/articles/cochrane-ends-the-masking-rage/
I know you would love to believe masking works and it seems it should. But the virions are literally 1/1000 the size of the holes in the mask fabric. The fact is that it has long been known that masking is ineffective except as a psychic prop to make people feel better. If it makes you feel better, go for it...no harm unless you are going to rob a bank as Vinay points out.
If you want to look at masking broadly, again there are hundreds of articles. Here are a couple you may find helpful: https://brownstone.org/articles/the-incredible-persistence-of-the-myth-of-masking/ and https://brownstone.org/articles/studies-and-articles-on-mask-ineffectiveness-and-harms/ if you want to see hundreds of articles on this.
Hope this is helpful.

In fact masks might be bad in an OR. Here’s one study from 30+ years ago, however, it wasn’t statistically significant.

Ok, you’re right. Don’t change a thing.
It's quite possible your long covid is a result of the Vaccine rather than covid. https://news.yale.edu/2025/02/19/immune-markers-post-vaccination-syndrome-indicate-future-research-directions
I have read the study. A possibility, yes, but a slim one. Also, it begins by saying millions of lives were saved by the vaccines. Only a tiny number get post-vax syndrome. Correct me if I'm wrong. So, therefore, what.....?
