How to fold your surgical mask to create a better fit and increase personal protection, per new CDC guidelines. #COVID19 #MaskUp
2) This is now critical. CDC advises now either double masking with cloth+surgical mask, or using the above technique to create a better seal with 1 surgical mask. Here is why: 🧵
3) critical point — Masking source and receiver yields different effects. Here is why.
4) Masking more important than ever when more contagious #B117 is spreading widely.

We need to call Moderna vaccine by the true proper name of “NIH-Moderna vaccine”. It was mainly developed at Fauci’s NIAID. Moderna honed its mRNA tech via DARPA grants & also didn’t disclose federal support in patents, violating Bayh-Dole Act. HT @mattbc.
2) @mattbc is right in calling out this nonsense by Moderna to hide it got tremendous federal support for the vaccine in its patent. This is a violation of the 1980 Bayh-Dole Act. And @moderna_tx possibly violated it by not disclosing in 154 patent apps.

3) Moderna vaccine works folks. @KizzyPhD from the NIH is famously one of the co inventors of the vaccine. But this doesn’t change that Moderna needs to publicly acknowledge in its patents that its vaccine was taxpayer funded and NIH co developed, akin to Oxford-AstraZeneca.

What is missing from this CDC school reopening priority list? Airborne virus guidance! Like almost nothing in 33 page document on ventilation except 1 paragraph on open the windows, but only if feasible. Ventilation should be #2 behind masks! #COVID19
cdc.gov/coronavirus/20… Image
2) Notably absent from new CDC guidance was ventilation. In one short paragraph, CDC suggested schools open windows & doors to increase circulation, but said they should not be “if doing so poses a safety risk or a health risk.” #COVID19 nytimes.com/2021/02/12/hea…
3) “C.D.C. gives lip service to ventilation in its report, and you have to search to find it,” said @j_g_allen, an expert on building safety at the Harvard T.H. Chan School of Public Health in Boston. “It’s not as prominent as it should be.”

Worrisome—UK 🇬🇧 data shows suddenly higher #COVID19 positivity % in England 🏴󠁧󠁢󠁥󠁮󠁧󠁿 (where #B117 highly dominant) in children ages 5-9, in both boys and girls, sustained each week over 4 consecutive weeks. Ages 0-4 positivity also increasing. Israel 🇮🇱 has also seen kids case trend. Image
2) As noted by @dgurdasani1, this is all despite these data really underestimating infection in children (as they are based on symptom based testing). And positivity rates appear highest in early year settings (fully open) & primary schools (20% attendance).
3) Dr @dgurdasani1 believe it is related to schools in England 🏴󠁧󠁢󠁥󠁮󠁧󠁿.

⚠️REINFECTION WARNING from the WHO.

“We are now getting reports of people getting reinfected with a new variant—from 🇿🇦 (#B1351)—suggesting people who’ve had prior infection could get infected again.” says Chief Scientist Dr. Soumya Swaminathan. #COVID19
2) This comes on the heels of troubling data I highlighted last week from the placebo group of the Novavax 🇿🇦 trial that that people previously infected and have #COVID19 antibodies (seropositive) has no protection for #B1351 variant reinfection— not even for severe disease!
3) Last month, South Africa’s CDC also warned about likelihood of reinfection risk because of the lower virus neutralization seen by the E484K mutation in the #B1351 variant.

Vaccinations have gone from 900k per day to now over 1.5 million.

I think Biden’s team under @aslavitt46 & @JeffZients @WHCOVIDResponse can push it to 2 million by the end of Feb / early March, and hopefully 3 million a day by mid April.

Let’s do it. #COVID19 (HT @CAPAction) Image
2) This is building back better.
3) These PSA campaigns with @Adweek and @WarnerMedia and @GalGadot are also effective.

Moderna says it has 631.5 mil doses of #COVID19 vaccines on order, of which a whopping 613 million are committed to rich countries like 🇺🇸 🇪🇺 🇯🇵 🇨🇦 🇰🇷🇨🇭🇬🇧 🇮🇱—almost none to developing countries. For COVAX, Moderna vaccine not listed among providers. Sad.
investors.modernatx.com/news-releases/… Image
2) Moderna says it has more countries not disclosed. Why? Poor countries likely wouldn’t hide it. The complete absence of Moderna from discounted COVAX vaccine providers shows where its values for humanity are. @moderna_tx — show you care. Donate to COVAX. gavi.org/sites/default/…
3) While most of COVAX vaccines to developing countries are Oxford AstraZeneca vaccines, Pfizer is also among them, even though it has ultra cold chain requirements. Moderna doesn’t need ultra cold storage. So @moderna_tx has no excuse. gavi.org/sites/default/… Image
