Dave Dixon’s updated charts, with various lag on reporting assumptions to try to match breakthroughs from the same time period with non-breakthrough ones. I gave you the raw date reported numbers in the post earlier today. I think we are heading to first a third of all cases being breakthroughs, then 40%, 50%, etc. It is almost inevitable as vax rates rise. Would love to know reinfections as well. And again, nothing to be concerned about. Lower absolute numbers, same age structure.

Summary: Cumulative incidence of COVID-19 was examined among 52238 employees in an American healthcare system. COVID-19 did not occur in anyone over the five months of the study among 2579 individuals previously infected with COVID-19, including 1359 who did not take the vaccine.
thats right 1359 unvaccinated people with prior infection …. zero breakthru’s …
yeah, I think it is becoming clear that immunity by infection is better than immunity by vax, although the combination in most studies is better yet. Of course, I don’t think it is advisable for most people to try to get their immunity from infection versus vaccination. In most groups the risk/benefit of that course tilts to vax.
