My interview with @US_FDA Commissioner @SteveFDA today @Medscape on the #SARSCoV2 vaccines, monoclonal antibodies, and rapid home tests 1/
medscape.com/viewarticle/93…
Recall I had sent an open letter to him August 31 after the convalescent plasma "breakthrough" press conference, w/o any supportive evidence, and the prior EUA on hydroxychloroquine medscape.com/viewarticle/93…
He didn't take either option I suggested. He called me. 2/
We've since spoken several times and now I understand his intentions, what he's been through, the immense pressures that have been placed upon him. For me, the trust in him and the FDA has been restored. 3/
EUA has become a buzzword, even now in the public domain. What is it? 4/
Fortunately, we got 4 Phase 3 vaccine full protocols released (after a lot of push thru social media + other routes). They each set out for completion at 150-164 events. How do you extrapolate this limited N of infection events to 10s-100s of millions people to get vaccinated? 5/
Many of the vaccine trials are run under Operation Warp Speed (OWS) with one Data and Safety Monitoring Board (15-20 members). Pfizer is on their own w/ a much smaller DSMB. All shoot for 50-60% efficacy, 95% lower CI 30%. What is OWS, how does it work? 6/
Does @SecAzar @HHS have the authority to issue an EUA without FDA's involvement? 7/
Reassuring: while that could happen Dr. Hahn has indicated that it won't 8/
Now onto what Dr. Hahn did to show independence from WH, Trump. He/FDA developed more stringent guidelines for a vaccine EUA. Sent them to the companies, Advisory Committee, and published on the FDA website this week 9/
These tighter guidelines with longer safety follow-up (2 months median) and inclusion of some severe infections in endpoints were blocked by Trump, White House for weeks 10/
The tighter EUA vaccine guidelines 11/
Winning the battle against the White House 12/

Despite that, later that evening Trump tweeted vs Dr. Hahn
This was all about getting a vaccine EUA's before November 3rd. That is now, fortunately, put aside because EUA tighter guideline w/ FDA internal and external reviews, makes it mathematically impossible 13/
Now onto the monoclonal antibodies. It's a very different picture than HCQ or convalescent plasma EUAs which did not have supportive evidence from any randomized trials 14/
The problem here is that there is an unmet need (early covid, high risk), some supportive data--nothing to do with Trump's treatment or his cure claims. How can the review be done with this cloud? Approved pre-November 3rd? 15/
We're into transparency. You are too. I've been asking some tough questions. 16/
Now onto rapid home diagnostic tests. Can't we get a new path at FDA and not use the PCR standard? 17/
Our final remarks. Stop the political interference. Let FDA do their work and it'll get done right.
18/end

Dr. Conley does it again. He clears Trump for public engagements in 2 days, without evidence that he is not infectious, without viral load data, without providing when/timeline he became infected.
Yesterday Dr. Conley ordered & reported a positive IgG antibody test in a patient who received a massive dose of IgG antibodies.
Today, without even committing to simple PCR tests to verify Trump is not shedding virus, he's cleared to meet with large crowds of unmasked people.
BTW CDC Guideline of 10 days (this is 9 days) is a *guideline*. This is a unique individual (in many ways) who received monoclonal antibodies, not expected to achieve mucosal immunity. And the early dexamethasone would suppress T cell response.

We had the distinct privilege of talking with @cmyeaton about the pandemic, for which she has been a leading light. medscape.com/viewarticle/93…
w/ @cuttingforstone @Medscape w/ transcript
@JHSPH_CHS
Here's some of the things we discussed and learned from @cmyeaton
1. What prompted her to become an epidemiologist?
2. Dr. Yeaton and colleagues wrote the essential report in April providing guidance for reopening. @JHSPH_CHS

If only the states had adhered to the guidelines, we could have achieved containment of the virus

On today's message from Trump about his mAb treatment: "The gave me Regeneron" "at my suggestion" "I felt well immediately"
He now claims: "I call it a cure," "I've authorized the EUA" "Everyone will get them free"
All false. All predictable.
The things said were so far off the truth I made a tabular summary

A rather important letter @ScienceMagazine just published that stresses #SARSCoV2 aerosol transmission (size < 100 μm) and what should be done about it.
By @kprather88 @linseymarr @mmcdiarm @Don_Milton and colleagues science.sciencemag.org/content/early/…
For background, this is the previous, now classic essay on the topic by @kprather88 and colleagues @ScienceMagazine science.sciencemag.org/content/368/64…

Did monoclonal antibodies save the President's life?
We'll never know, but it's possible and the implications are profound.
Let me explain 1/
Trump's risk profile by demographics was high (age, male, obesity) but it markedly increased when he had blood oxygen desaturation, had an abnormal lung CT scan of pneumonia, and was hospitalized
Mortality risk > 32% isaric4c.net/risk/ 2/
Sometime on Friday (<-presumably) he received a monoclonal antibody cocktail (2 different antibodies to override the potential of a virus escape variant)

The lies are coming out now
1. There was a rapid decline in oxygen saturation Friday
2. He received supplemental oxygen
3. He had a high spike in fever
4 .Lung CT abnormal
5. Transferred expediently d/t change in condition
time.com/5895970/trump-…
Now dexamethasone has been added to the kitchen sink of drug interventions. For his "brief" need for oxygen? (compared with no oxygen). Patients in the pivotal trial showed no benefit, and potential harm, if oxygen was not received.
Examples of the extreme deception
—How low did the oxygen saturation go? In the low 90's?
—It did not go into the low 80's

—What did the lung scan show?
—The expected findings
