There is a directive relating to vaccination supplies due to COVID aimed at manufacturers. Essentially if you are going to continue subq you will probably need to switch to insulin syringes. I use 25 gauge as well but 1 inch and after scouring for weeks was able to find 5/8 inch tuberculin syringes. They are out there but hard to find.Has anyone noticed a shortage of supplies? I usually order from OTC. I can’t find any 25g subq needles.
