What is the first step in drawing vaccine from a vial?

• A. Remove protective cap on the vial
• B. Clean off the diaphragm with an alcohol swab
• C. Pull back the plunger to aspirate the needed amount of air
• D. Insert the needle in the center of the rubber diaphragm

Answer: (A)

Accessing the vial safely starts with removing the protective cap to expose the rubber stopper. You can’t disinfect or access the contents without revealing the stopper, so this step comes first. Once the cap is off, you clean the stopper with an alcohol swab to reduce surface contamination, then proceed with drawing the vaccine by preparing the syringe, drawing air if your protocol requires it, and finally pulling vaccine into the syringe. The other steps depend on having access to the stopper, so removing the cap first is the essential initial move in the drawing process.
