How to use a bifurcated needle to perform multiple puncture vaccination technique

Vaccines that use a multiple puncture technique are administered directly through the skin (i.e., percutaneous

route) of the deltoid area on the upper arm with a sterile bifurcated needle.

A bifurcated (i.e. two tipped) needle has a flattened end cut into two short prongs. When the fork of the needle is inserted into the vial, the gap between the prongs holds a droplet of vaccine sufficient for vaccination.
