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.
