aspiration is a hot topic but it's also common sense I have aspirated and also have not it depends on the person and how big they are (as in how much fat they have on them) but the vaccinators aren't trained to aspirate it's not that easy to do with some patients or for a newly trained injector to perform but the risks are a hotbed of debate
with 200k cases today aspiration is not on the list of worries for me it, it's catching the virus that's my top worry and still watching maskless people saying it has a chip in it or it is not tested etc etc etc
edit I would of thought by now a small auto inject pen or such like would have been introduced but that depends on the vaccine and how its administered but it would take the headache out of injecting
