Ah I see what you mean, but live-attenuated might be quite different from the mRNA vaccines. I wonder if the study authors at the outset expected the impact to be similar. What I find dismaying is that this tiny study is the first and only examination of the impact on broader immune response from the mRNA vaccines (at least, that I have been able to find) after millions of doses were already administered.
