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.

[Pratha Sah, PhD @Pratha_Sah]

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

Since our COVID-19 vaccination campaign began, we estimate 48,000 lives have been saved — and an immense amount of suffering avoided — due to vaccines.

“Encouraging people who are already vaccinated to get boosted should in theory be much more straightforward,” said @Pratha_Sah.

@AnisabelBento Haha. I oddly feel validated 😂

[Yale School of Public Health @YaleSPH]

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!

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 https://t.co/X0N1og0i2u

The first U.S. COVID vaccine was given a year ago this week.

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

[Prof Peter Hotez MD PhD DSc(hon) @PeterHotez]

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

[Pratha Sah, PhD @Pratha_Sah]

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

[Eric Topol @EricTopol]

What if Texas and Florida had vaccinated at the level of New England by July 31st?

Prevention of:
Deaths: Texas 6,353, Florida 16,235
Hospitalizations: Texas 37,587, Florida 61,327

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

[Yale School of Public Health @YaleSPH]

Through March 2022, increasing daily COVID-19 vaccination by 50% would prevent approximately 19,500 hospitalizations and 6,900 deaths across 10 states studied, find YSPH's @Alison_Galvani & @Pratha_Sah & colleagues from @commonwealthfnd & @yorkuniversity.

[Dr. Sanjay Gupta @drsanjaygupta]

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

[Pratha Sah, PhD @Pratha_Sah]

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

[Annals of Int Med @AnnalsofIM]

Study from @YaleSPH and @yorkuniversity suggests U.S. population immunity against #COVID19 still insufficient to resume pre-pandemic social behavior. Increased #vaccination needed to prevent additional waves, evolution of novel variants. @Alison_Galvani https://t.co/mp2VYIJrqZ
