Excellent graphic in De Volkskrant today. Who infects who? The top labels are Source, with unvaccinated on the left and vaccinated on the right, the side labels are Recipient, with vaccinated on top and unvaccinated on bottom.
@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.
@holly Thanks for sharing this! The conclusion I get, seen in bands sloping up from left to right, is that mostly people infect others their same age, but the next significant effect is with those a generation or two older or younger.
