Hi - I am currently precepting a couple pharmacy students. One of them has extremely poor skills as well as confidence regarding giving immunizations. He definitely needs more practice before I'd feel comfortable letting him immunize patients. I am willing to let him give me a flu shot, but I want him to practice with something else first. What kind of solution is used for practice injections? Saline? And where would I get it from? I'm assuming the 0.9%? We somehow ended up with some extra vials of diluent vials from other vaccines, but it just says it is sterile water. Probably not best to use that? Thanks for any advice.
