At what point will we know more about whether vaccinated people can still carry the virus and infect others? With millions of people already vaccinated shouldn't we have decent data on that already?

So far the best data we have on this are from the AstraZeneca vaccine, which was covered in the 2-3-2021 issue: https://covidtransmissions.substack.com/p/covid-transmissions-for-2-3-2021

To see the effects at a population level, we are going to need extremely high uptake in one large geographic region with good epidemiological surveillance. No country is quite where we need to be for that yet, but the closest candidate is Israel.
