Hello, I have to say you are overthinking this. I currently give the vaccine to nursing home through cvs. There are 2 forms thr patients have to fill as consent to get the vaccine. They basically fill in their demographics, and the form asks if they have any comorbidities. You document the date, time, temperature of the pt., location of injection, sign, print, title. The pharmacy drawing up the vaccine is good because that's the part that needs good timing. The vaccines have to stay frozen at a spec. Temp. Once they are out to thaw, for 30 mins, they must be diluted with normal saline and 6 shots drawn. Once the shots are drawn in a syringe, they are good for 1 hr. If you leave the diluted vaccine in the vial, it's good for 6 hours. It is easier to have pharmacy handle that whiles you focus on injections. It's simple. Ask any questions, I'll answer if I know.
