💡Potential RNA therapy against #SARSCoV2 infection via lipid nanoparticle delivery on horizon. Small-interfering RNAs (siRNAs) targeting the virus were screened that effectively inhibit virus by >90% either alone or in combination. #COVID19 (link below)
2) “A SARS-CoV-2 targeted siRNA-nanoparticle therapy for COVID-19”
3) “Encapsulation of siRNAs in LNPs followed by in vivo injection ➡️ robust repression of virus in the lungs and a pronounced survival advantage to treated mice. Our LNP-siRNA approaches are scalable and can be administered upon the first sign of SARS-CoV-2 infection in humans.”
4) “We suggest that an siRNA-LNP therapeutic approach could prove highly useful in treating COVID-19 disease as an adjunctive therapy to current vaccine strategies.”

After 15 million doses of J&J vaccines earlier ruined by Emergent’s factory, it’s further revealed >100 mil doses are on hold as FDA checks for possible contamination. Emergent has long troubling record—but Trump WH awarded big contract anyway.🧵#COVID19 nytimes.com/2021/05/19/us/…
2) In more than three hours of testimony before a House subcommittee, the chief executive, Robert G. Kramer, calmly acknowledged unsanitary conditions, including mold and peeling paint, at the Baltimore plant.
3) He conceded that Johnson & Johnson — not Emergent — had discovered contaminated doses, and he fended off aggressive questions about his stock sales and hundreds of thousands of dollars in bonuses for top company executives.
BREAKING—Oklahoma State Department of Health announced that it identified a cluster of 17 cases of the #B16172 variant, including 3 that were in fully vaccinated people. 2 others were partially vaccinated. Travel didn’t play a role. oklahoman.com/story/news/202…
2) “Dr. Dale Bratzler, the chief COVID officer for the University of Oklahoma, said data indicates B.1.617.2 variant — also called an India variant for where it was first detected — is about 6 times [lower neutralization] than other variants to antibodies generated by vaccines.”
3) That said, “Department of Health officials said last week that vaccines are still thought to provide some protection against the India variant, and contact tracing efforts were underway to learn more about the infections.”
TRAGIC—A key doctor & 12 of his family was killed in a Gaza air strike. Dr Abu al-Ouf was head of internal medicine at the Palestinian territory's main hospital, & oversaw al-Shifa's hospital response to #COVID19. The 12 dead included 2 of 3 of his kids. bbc.com/news/world-mid…
2) As well as being in charge of internal medicine at al-Shifa hospital in Gaza City, Dr Abu al-Ouf oversaw its response to COVID.
He supervised the treatment of an entire ward of people with severe Covid-19 in a place where there are few specialists in respiratory illnesses.
3) He also trained students from two local medical schools. "To get someone as qualified as Ayman, you need at least 10 to 15 years of training," said Dr Zaanin, who named his own daughter Tala after his friend's.
A top Japanese medical organization now calls to cancel the Tokyo Olympics saying hospitals are already overwhelmed as the country battles a spike in #COVID19 infections less than three months from the start of the Games. 🧵
2) The Tokyo Medical Practitioners Association representing about 6,000 primary care doctors said hospitals in the Games host city "have their hands full and have almost no spare capacity" amid a surge in infections. reut.rs/3tWE2jA
3) "We strongly request that the authorities convince the IOC (International Olympic Committee) that holding the Olympics is difficult and obtain its decision to cancel the Games," the association said in a May 14 open letter to Prime Minister Yoshihide Suga
STOP VARIANTS—The AstraZeneca vaccine is ineffective for mild and moderate #B1351 variant from South Africa 🇿🇦. Prior to Oct 31st (before B1351), 75% effective for non-B1351.
2) Look at the efficacy yourself — it is incredibly low overall 10-20% and not significant (not distinguishable from 0%).
It was only 75% in early part of the trial before #B1351 emerged.
3) Lots of questions about vaccines versus Indian variant #B16172– we just don’t know yet.
But what I worry is if some of the bad variants mix together and do recombination inside of a co infected person with both variants/strains… that could be very bad.
Different types of #COVID19 and vaccine hesitancy — the most worrying kind is “COVID skeptics”—the least likely to get vaccinated. The primary barrier for people are deeply held beliefs about Covid & at least one conspiracy theory. They are 14%. Oy.🧵 nytimes.com/interactive/20…
2) Covid skeptics believe supposedly “that microchips are implanted with the Covid vaccine; Covid-19 has been exploited by the government to control people; or that the pandemic was caused by a ring of people who secretly manipulate world events.” 🤦🏻♂️
3) “Covid Skeptics are common in Arkansas, North Dakota & Nevada. Considering that 84 percent of this group believe that the government is exploiting Covid-19 to control people, leaders of vaccination campaigns should consider tapping nonpolitical figures to mobilize this group.
