I work in a Doctors Office. The type of vaccine you get depends on who you buy your vaccine from. We usually always get the multi vial bottles. Its 10 injections in one bottle. So you take out a syringe draw up 1cc from the bottle then give the injection and toss the syringe One year we got the pre-filled syringes, but we didn't like it. The syringe in smaller and was cumbersome to hold! (just our opinion.) Some distributors have the pre-measured syringes made up already. It has the vaccine in it already and the needle is usally attached. You give the injections and toss. (its more convenient ~ but usually cost a little more due to the syringe and needle already being all ready go.)
