Wow—Cuban 🇨🇺 government says it is on the brink of a successful #COVID19 vaccine invented in Cuba & mass production for export. 1 of 4 vaccines developed by Cuban scientists will enter final phase of testing next month. It may even offer it to tourists.
nytimes.com/2021/02/17/wor…
2) The vaccine heading for Phase 3 trial, is called Sovereign 2, in a nod to the pride the island takes in its autonomy. Already, Cuba is floating the idea of enticing tourists to its shores with the irresistible cocktail of sun, sand and a shot of Sovereign 2.
3) Vicente Vérez, one of the scientists leading the team that developed the vaccine, has said that the island could offer vaccinations to all foreigners who travel there.
4) Cuban scientists say the government will probably give away some doses to poor countries, in keeping with its longstanding practice of strengthening international relations by donating medicine and sending doctors to address public health crises abroad.
5) “Cuba always donated vaccines,” said Gerardo Guillén, a scientist developing two of the four vaccines at the state-owned Center for Genetic Engineering and Biotechnology. “We help other countries.”
6) Cuba’s investment in public health gave rise to dozens of medical research institutions and a surplus of doctors, which Cuba sends to other countries in medical missions.
In 2019, the leasing of doctors, nurses and technicians brought in $5.4 billion, twice as much as tourism
7) “The island’s biotech sector is also well developed. Cuba makes eight of the 12 vaccines administered to children on the island and exports vaccines to more than 30 countries.
“It is a biotech juggernaut,” said Gail Reed, the editor of MEDICC Review
8) “Cuban scientists have also developed innovative treatments, including a lung cancer vaccine, which is in trials with the New York-based Roswell Park Comprehensive Cancer Center.
9) “Sometimes people think because it’s Cuba, they’re just making these drugs in their garage and giving them to people, and that’s not true,” said Candace Johnson, Roswell Park’s president.
10) “They’re very much practicing with exactly the same high standards that every other country does producing these drugs.”
11) Producing the coronavirus vaccine was made more complicated by the Trump administration’s tightening of sanctions on Cuba. Scientists say they haven’t been able to buy all the equipment and raw materials they need, including spectrometers.
12) “The two research groups working on the drug have only one that is powerful enough to analyze the vaccine, Dr. Guillén said, and it’s about 20 years old.
“Cubans not only are able to make old cars still work, they can manage to make old equipment work,”
13) The Sovereign 2 vaccine has progressed through two phases of trials and is set to enter a third phase, where it will be tested on around 150,000 people in Cuba and in Iran. Mexico is also in talks with the Cubans to participate in the third phase of trials.
14) Like the vaccine being developed by Novavax, a U.S. company, Sovereign 2 is a protein-based vaccine that contains part of the coronavirus. It requires three doses administered in two-week intervals

Madness—NCAA will bring fans back to the stadiums for the men’s and women’s NCAA basketball 🏀 tournament—albeit at lower capacity. But having thousands of fans arrive from all over the country creates #COVID19 super-spreader risks—as well as bars/hotels.
nytimes.com/2021/02/19/spo… Image
2) The 68-team men’s tournament, which begins on March 18, will be played in Indianapolis before crowds of up to 25 percent capacity at sites ranging from the quaint 9,100-seat Hinkle Fieldhouse to Lucas Oil Fieldhouse, which holds up to 70,000 fans.
3) The 64-team women’s tournament, which begins on March 21, will allow up to 17 percent capacity from the regional semifinals through the championship final in San Antonio. Those games will be played at the Alamodome, which has a 31,900-seat capacity for basketball.

I’m worried about Texas COVID—

“We could all huddle in one house” was Heidi Cruz’s first suggestion to stay warm with her neighbors when power went out. I know shared heat is nice & neighborly, but I think it will likely trigger more #COVID19 outbreaks.

2) I tried not to say this quiet thought aloud but I’m seeing and hearing other people worry too. Yes there is a humanitarian crisis and yes hypothermia kills, but we can still be worried about COVID too.
3) I have no pity for Heidi Cruz. But this isn’t about just her. This is about public health.

📍Pardon my vent about insufficient ventilation / air exchange & school policy. Air exchange (via fresh air or disinfection) is really important for reducing #COVID19 transmission—we should aim for 5-6 air exchanges per hour. Achieving 5-6 is harder, but should we give up? No!🧵 Image
2) President Kennedy once said, we choose to goto the moon 🌙 not because it is easy, but because they are hard—and important. Some think asking for sufficient school ventilation is like asking schools to goto the moon. No, not true! It’s possible. We can do it.
3) First there are ways to ventilate without HEPA filters or full windows. You can even with 1 door. 2 doors better. Here is how to ventilate your school classrooms if unable to open window. #COVID19

I’ve been very worried about Austria 🇦🇹 #B1351 outbreak — the largest pocket of B1351 outside of South Africa 🇿🇦.

If you can read German, my interview with @DiePressecom maybe of interest. #COVID19 #COVID19at

Outbreak of 69 #COVID19 cases in 2 schools, plus 20 at daycare centers in one Danish city—all #B117. “Something going on with the infection of [🇬🇧 variant] #B117 among children that we have not seen with the old coronavirus” says an epidemiologist. 🧵

2) Two schools and eight daycare institutions in the central Jutland city of Kolding will remain closed until Friday following coronavirus outbreaks that experts claim underline the devastating potential of the British variant of COVID-19.
3) Speaking to DR, Viggo Andreasen, an professor at Roskilde University who is swiftly becoming favorite 🇩🇰 epidemiologist, questions whether there is “something going on with the infection of #B117 among children that we have not seen with the old coronavirus”.

BREAKING—new #COVID19 vaccine efficacy study from Israel concludes that Pfizer/BioNTech's jab is up to 85% effective after the first dose after 15 days to day 28—and even 75% including asymptomatic cases—meaning it stops infections by 75%! Huge. 🧵

2) The research, conducted by the Sheba Medical Centre, the country's largest hospital, has been published in the Lancet medical journal.

The hospital assessed the effectiveness of the first dose of the Pfizer/BioNTech vaccine among 7,000 of its healthcare employees.
3) Professor Eyal Leshem, an infectious disease expert and director of Sheba's Institute for Travel and Tropical Medicine, told Sky News: "This is first real-world evidence of effectiveness that shows up after the first dose of the vaccine.” 👀
