This @PHE_uk chart on antibody seropositivity looks really good compared with the last update two weeks ago!
— Covid Fact Check UK (@fact_covid) April 15, 2021
70-84s: 97.7%(was 93.5%)
60-69s: 81.1% (was 61.0%)
50-59: 52.8% (was 37.8%)
These results are taken from blood donors. PHE use a 4-week period midpoint (weeks 10-13). https://t.co/mpDEAcy5r6 pic.twitter.com/3NVxrAjAZh
