Positive vaccine news! An initial statistical analysis estimates that vaccinated people who do test positive for the coronavirus in PCR are likely to be LESS infectious. @erlichya's team estimate these people have 1.6x to 20x lower viral load than unvaccinated people.

Read the thread for how @erlichya and the @MyHeritage team estimated this difference from the lab data they were seeing.

Note, too, that this is in addition to the big estimated increase in vaccinated people who aren't testing positive in the first place.

Summing up these two pieces of research:
1. The Pfizer vaccine seems to be reducing infection (ie positive tests) by 66-85%.
2. For those who do test positive after vaccination, they seem to be less infectious (1.6-20x less viral load)
