The Delta variant: updates from the new @PHE_Uk report
assets.publishing.service.gov.uk/government/upl…
1st dose vaccine (either AZ or Pfizer) quite protective vs hospitalization
Fully vaxxed vs unvaxxed:
Infections 7.7% vs 67%
Hospitalizations 8% vs 48%

Delta's secondary attack rate is coming down some in the latest dataset. Its enhanced transmission over alpha appears to be more in the 40-60% range

Reinfections by sequencing data: 311/1260 were Delta

This 71-page report is rich. And that 60% of infections are getting sequenced (91% are Delta) is quite impressive.
It makes the output from CDC and the genomic surveillance in the US particularly weak

Here is the latest @CDCgov variant report. It is from May 22 and it's frankly pathetic when you compare it to @PHE_UK, both with respect to it being out of date and the lack of sequencing in the US

Contrast today's @PHE_UK report from genome sequencing (60% of cases) up to 4 days ago -- >60,000 Delta cases with vaccination status and outcomes
