📍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!🧵
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

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. 🧵 news.sky.com/story/covid-19…
2) The research, conducted by the Sheba Medical Centre, the country's largest hospital, has been published in the Lancet medical journal.

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.” 👀
Sudden Kindergarten outbreak—a once small #COVID19 outbreak in an Austrian🇦🇹 kindergarten exploded from 10 cases Monday to suddenly *32 cases* by Wed—20 cases in kids, 12 adults & caregivers.
2) “some caregivers complained of symptoms on Saturday. They were then tested positive for SARS-CoV-2 on Saturday, despite negative rapid tests on Friday. Already on Sunday, the parents of the 75 kindergarten children were informed via the kindergarten app "KidsFox".
3) “Since then, all children and caregivers have been quarantined, the kindergarten and, for safety reasons, the afternoon care KiLo, are closed until further notice.”
