Our preprint received lots of attention and this is the final and peer-reviewed version of our analysis of the first 100 days of the rapid NHS vaccine campaign

Healthcare activity during #Covid19: by September 2020, laboratory tests reached near-normal levels, recorded respiratory infections showed a sustained drop, not returning to pre-pandemic levels, and #COPD reviews remained below baseline #OpenSAFELY doi.org/10.3399/BJGP.2021.03…

We've just released another set of vaccine reports (data up to and including 12th January 2022). From this week, we will be publishing vaccine reports fortnightly rather than weekly. Do get in touch if this will cause you problems! reports.opensafely.org/repor…

Analysis of 57.9m patient records found that by 17 March 2021, 36% of patients in England had received their 1st dose of the #Covid19 vaccine, including 95% aged ≥80 years not in a care home #OpenSAFELY doi.org/10.3399/BJGP.2021.03…

Thanks to @OpenSafely team, as always, and in particular @drchrisbates and the engineers who built this method for identifying care home residents in TPP data using an address linkage. Limitations noted here wellcomeopenresearch.org/art… (a revision based on peer review ongoing).

A new study of 4.3 million adults over the age of 65 shows that #COVID19 has had a disproportionate impact on the mortality of care home residents in #England compared to older residents of private homes, but only in the first wave. @AnnaTheresia 👇 thelancet.com/journals/lanep…
