It's quite probably just a physical thing. The injection is forcing
muscle fibres apart to take the volume of the vaccine (0.3 or 0.5 ml for
Covid, 0.5 ml for 'flu). If the injection is 0.3 ml it won't have as
much damaging effect as 0.5 ml. Unless, of course, the former happens to
be much nearer to a sensory nerve than the latter.
