Dr Fauci slide on #covid19 vaccines and when results are expected, from first White House Covid-19 response briefing:
Dr Fauci slide on coronavirus variants of concern:
.@ASlavitt now presenting at WH #COVID19 response briefing. “It’s been a busy 7 days.”
.@ASlavitt notes @POTUS is pushing #covid19 team to view 1M shots a day "as a floor, not a ceiling."
.@ASlavitt: plan is to maintain rolling inventory of 2-3 days’ supply of #covid19 vaccine. But passing doses to states very much in real time as they order them.

In this new pre-print from the lab of AIDS research pioneer David Ho, suggestions the B.1.35 variant (as expected) has a bigger impact on potency of both antibody drugs and #covid19 vaccines (1)
Neutralizing activity of Moderna & Pfizer vaccines declines only about 2 fold against B.1.1.7 variant, but 8.6 and 6.5 fold against B.1.351, Ho pre-print finds: (2)
On monoclonal antibody activity against the variants (SA9 is B.1.351.), one Regeneron antibody loses potency, but cocktail retains. Lilly single antibody & cocktail appear to lose potency against B.1.351. (Note Regn’s Christos Kyratsous is a co-author on paper) (3)
Biden signing 10 executive orders and other directives today on #covid19. Here they are per @WhiteHouse fact-sheet: 🧵
1. EO directing agencies to fix supply of PPE, materials for testing & vaccines, including through Defense Production Act
2. Presidential Memo directing FEMA to increase federal reimbursement to 100% (from 75%) of cost of National Guard personnel & emergency supplies; restoring full reimbursement for eligible costs to support safe school reopening through FEMA Disaster Relief Fund
3. EO to establish Pandemic Testing Board; increase testing capacity by directing use of Defense Production Act; promote surge capacity of testing in the US; onshore test manufacturing, expand public health workforce, support #covid19 screening for schools;ensure equitable access
I enjoy the "Mean Girls" parallel of the title of this HBR session about to start: "When Dr Fauci Thinks 'Normal' Will Happen" linkedin.com/video/live/urn…
HBR host notes Dr Fauci got his second dose of Moderna vaccine today
Fauci: If we can get 75-80% of the population of this country fully vaccinated over a period of several months, we will have an umbrella or cloak of herd immunity that would completely turn around the dynamics of the outbreak.
Still confused about the 2nd dose vaccine supply? Me too, but I think this is what happened: 🧵
Let’s go chronologically. Last Thursday, governors wrote a letter to @SecAzar requesting second doses not be held in reserve and instead immediately be made available:
3. Tuesday @SecAzar said OWS would make the change as well.
Azar: "We can now ship all of the doses, that had been held in physical reserve with second doses being supplied by doses coming off of manufacturing lines with quality control going forward."
