We are so proud of the REACT study. Thank you to everyone involved across the studies from partners to collaborators and especially everyone who participated.
Our important work will continue with further research into the longer-term impacts of #COVID19.
To everyone who helped make the #REACT study happen, from scientists to kit makers, lab technicians to everyone else involved, and all those who supported them - thank you! 👏👏👏
"The data we've gathered is a really precious resource.
"Now that we have this resource, we want to make the best use of it for public good."
In a new feature, we look back at 5 of the most important things the REACT study has taught us.

🆕 Our latest publication in @NatureComms looks at the number of people affected by persistent #COVID19 symptoms in over 600K people in England.
We also identified a number of factors linked with a higher risk of lingering symptoms [🧵].

"Throughout the pandemic, surveillance studies such as REACT and ONS have provided vital insights into disease prevalence over time.
"I was alarmed by the news that the REACT programme was discontinued."

[🧵] Our latest and final REACT-1 survey has recorded the highest number of #coronavirus infections in England since we began our surveillance in May 2020.
Tests on over 100K people from 8-31 March showed 1 in 16 had the virus.

[2] We found that 6.37% of the population in England was infected in March.
This is more than double our previous findings when 1 in 35 had the virus in Feb and 40% higher than the first Omicron peak in Jan.

#ICYMI: Yesterday we published new findings from our #coronavirus study.
"Infections are still very high and the possibility that they are rising in older adults may be cause for concern," REACT director Prof Paul Elliott.

"We never know what to expect as the whole epidemic has been full of surprises, but it's given us cause for concern as older people are more vulnerable, and rising infections could lead to more serious illness."
REACT lead Prof Elliott on @BBCr4today: bbc.co.uk/sounds/play/m00154…
🆕 Findings from our surveillance study:
- #Coronavirus prevalence has been falling but remains high
- 1 in 35 was infected in February
- Infections are flat or rising in over 55s
- Proportion of BA.2 Omicron offshoot has risen substantially

🆕 Our paper in @NatureComms is the largest study to look at factors linked with antibody response to #COVID19 vaccination:
➡️ Declining response with increasing age
➡️ Higher response in those receiving an RNA vaccine
➡️ Lower response in men vs women

"Our results reinforce the importance of vaccination and booster campaigns."
🆕 Findings from our REACT-1 study in December have been published in @ScienceMagazine.
📉 #Coronavirus prevalence fell in boosted adults and vaccinated children.

#ICYMI: On Wednesday we released our latest findings👇
➡️ Infections rose >3-fold between Dec-Jan, peaking around 5 Jan
➡️ Recent trends show the fall may have stalled at a very high rate
➡️Infections are rising in children, dropping in adults

🧵New data from our REACT study show that #coronavirus infections in England may have plateaued at a very high level, with the highest recorded prevalence since the study began in May 2020.
1 in 23 had the virus in January.

🧵The preprint was amended to take account of and highlight limitations in the self-reported infection history data, which mean it is uncertain what proportion of the results are reinfections or recent infections picked up due to the sensitivity of PCR testing. @whippletom
