@holly Also interesting. Vaccinated people are more likely to infect other vaccinated people than unvaccinated people. Although the protecting works for source (less virus) and receiver (immunity).
I presume that is because vaccinated people hang around more with vaccinated people than unvaccinated people.
@uglyhack Right, there are 2 times more vaccinated people than unvaccinated people. Then the differences is gone or at least one would need to have the data to compute the difference.
If they are about equal, that is still interesting and somewhat unexpected given that vaccines protect the receiver.
Something else we may want to consider are data errors, given the small numbers. Couples called source and receiver may have been both infected by a 3rd person.
