When administering vaccines, it is important to make sure that syringes are labeled so that the products are not accidently mixed when refilling syringes. Mixing different products in the same syringe can reduce efficacy.
There are multiple techniques that can be used to label syringes. A marker can be used to write on the handle of repeating syringes. Different colored tape can be applied to syringes. A colored marker can be used to draw a line on the plunger of plastic syringes. When using colored tape or markers, make sure to apply the same color to the vaccine bottle.
