Many thanks @AlisynCamerota @VictorBlackwell for hosting me with @celinegounder on new mask rules, based on 1) steep declines in virus transmission, 2) vaccine availability, 3) the science showing reductions in asymptomatic transmission and virus shedding 
This third point is very interesting and based in part on a recent paper from Technion in Israel 🇮🇱 published in @NatureComms nature.com/articles/s4159…
It shows vaccinations also reduce virus shedding in asymptomatic individuals, it means that vaccinated parents need to worry less about transmitting virus to their unvaccinated kids
It also means that asymptomatic PCR + individuals who are vaccinated are probably not shedding enough virus to transmit the disease. This still needs further clarification but if it hold up it would have game changing implications...
For instance it would suggest that we might halt regular workplace screening for those who are vaccinated, including sports teams. On that basis we might cease routine screening for vaccinated @MLB_PLAYERS and prevent difficult situations like the one facing @Yankees
And remember that’s coming from an @astros fan..
