The pandemic has highlighted the increased risk of airborne transmission risk in INDOOR environments w/out ventilation. But it turns out we know very little about rates of indoor activity and how this varies by location. A 🧵on a new study in which we start to fill this gap (1/)

(1/3) We've said it before and we'll say it again: VACCINES. SAVE. LIVES. New research from YSPH's @Alison_Galvani, @Pratha_Sah, @abhiganit & colleagues from @commonwealthfnd finds COVID vaccinations have now prevented 2.2 million deaths & 17 million hospitalizations in the U.S.

Vaccines work! Our new analysis in collaboration with DOHMH shows that the vaccination campaign in NYC saved over 47,500 lives and prevented over 300,000 hospitalizations from December 14, 2020, through January 31, 2022. With @Alison_Galvani @ThomasVilches1 @EricSchneiderMD

“Encouraging people who are already vaccinated to get boosted should in theory be much more straightforward,” said @Pratha_Sah. https://t.co/NzqBkDFFAT

COVID vaccines have prevented 1.1 million deaths and 10.3 million hospitalizations in the U.S., according to a recent study by @YaleSPH researchers @Alison_Galvani and @Pratha_Sah and @commonwealthfnd. Thanks for sharing these findings, @BillGates!

(1/6) Three @YaleSPH research publications that advanced science and influenced policy have been identified as among the best papers of 2021 by @AnnalsofIM, @Health_Affairs & @commonwealthfnd: https://t.co/hCbCSAHUzL

The #COVID19 vaccine rollout in the US saved an estimated 240,000 lives and averted 1.13 million hospitalizations from the start of vaccination campaign to June 30, 2021. @Alison_Galvani @Pratha_Sah @MeaganCFitz @abhiganit

"While the Omicron variant is posing a new threat to overburdened hospitals and health care workers, rapidly increasing the pace of booster vaccination could blunt its impact." - @YaleSPH's @Alison_Galvani & @Pratha_Sah w/ colleagues from @commonwealthfnd https://t.co/9GaQg6lpak

A new study from @YaleSPH & @commonwealthfnd finds that COVID vaccines have saved 1 million lives and prevented 10 million hospitalizations in the U.S.: https://t.co/CN0NLoyO2i The first U.S. COVID vaccine was given a year ago this week. @Alison_Galvani @Pratha_Sah

1 👏 MILLION 👏 LIVES 👏 SAVED 👏 New research from @YaleSPH's @Alison_Galvani, @Pratha_Sah & colleagues at @commonwealthfnd on the lifesaving power of COVID vaccines ⬇️

@EricSchneiderMD @Alison_Galvani @Pratha_Sah and on the impact of year 1 of the U.S. #COVID19 vaccination campaign.

So now with @Alison_Galvani @YaleSPH we've actually measured the adverse health impact of this antiscience aggression and rhetoric. As we've just reported in @TheLancetInfDis that's 16,235 unnecessary deaths in state of Florida https://t.co/ufMo00EB7b

Our new study shows that a total of over 22000 deaths and 98,000 hospitalizations could have been prevented in Texas and Florida by the end of July if those two states had vaccination coverage of ~74% like New England states. w/ @Alison_Galvani @PeterHotez @EricSchneiderMD

We projected the impact of increasing vaccination rate in 10 US states, incl 5 in the south past the Delta surge peak. Accelerating vaccination in these states can save 6000+ lives between Sept and March. It's still not too late to save lives! w/ @Alison_Galvani @EricSchneiderMD

Good news for parents this morning. For the first time, we have vaccine data for children age 5-11. It is early and still needs to be peer-reviewed, but looks good. "Safe” and a “robust” antibody response." And, this age group makes up ~9% of the population. @Pfizer

In our new study, we estimate that overall population immunity (vaccine induced+naturally acquired) in the US was 62.0% as of July 15th. Not enough to go back to normal, esp. with the continued emergence of highly transmissible #COVID19 variants. w/ @Alison_Galvani

“The bottom line is that vaccination saves lives,” @Alison_Galvani explains to @yaledailynews. How many lives? Hundreds of thousands in the U.S. alone, find Galvani and @Pratha_Sah in a recent study with @commonwealthfnd. https://t.co/UuWeGeazet

#COVID19 vaccines have saved hundreds of thousands lives in the US and have kept even more Americans out of hospitals. Great article by @yaledailynews on our recent work 👇
