I had a pessimistic thought...if we observe that vaccinated people have a much smaller proportion of asymptomatic infections, maybe that means that vaccinating people is creating significant selective pressure towards more symptomatic and severe illness. I mean, I understand that for now, the vaccine greatly reduces serious illness. But relatively speaking it sounds like it is selecting for it and I wonder if we will see the effects in a few months. To be clear, my speculation implies to me that it is if anything more urgent to get vaccinated, because the more people are vaccinated, the worse things will get for the unvaccinated.
