Not yet, but you can kinda see it from the data. For Pfizer it was 60-70 after one dose already, iirc

  That's only if you include all infections within the two week window between shots. If you look at the tail end (ie, after the shot has time to be effective) it seems more like 90.

    The issue with this is that it's the SECOND shot that gives you your long term immunity. If you only get one shot your immunity is allegedly going to wane somewhat quickly. edit: for pfizer & moderna.

      Where did you see that part? Any reason why the 2nd one makes it last that much longer?

        That is typically how the second shot works. We don't actually know. It is possible the second shot isn't needed at all. It is possible that the first shot works for 45 days and then stops working completely. Experts doubt both of these extremes, but cannot actually say they are false because they don't know.
