Important new @UKHSA report today sheds light on key Omicron concerns
assets.publishing.service.gov.uk/government/upl…
1. BA.2 Vaccine effectiveness holds up very well compared with BA.1 *with booster*
2. The vaccine effectiveness (VE) vs Omicron symptomatic infection vs Omicron falls off 15+ weeks, as was seen with the Israeli data, here more so with Pfizer compared to Moderna
3. But protection (VE) vs Omicron hospitalization remains quite high (Moderna > 90% thru 9 weeks)
4. First read out for VE vs Omicron fatality, in age 50+
95% with booster (59% without)
5. Summary data for VE vs Omicron over time for each outcome strongly reinforces the booster/Dose 3 impact and the high level of protection maintained vs hospitalization out to 6 months👍
