What size is the most accurate syringe?

• A. 1 mL
• B. 5 mL
• C. 0.1 mL
• D. 10 mL

Answer: (A)

Measuring an injectable dose relies on the syringe’s capacity and how finely its markings are spaced. For typical vaccine doses around 0.5 mL, a 1 mL syringe provides readable, evenly spaced markings that allow you to measure the dose accurately and comfortably. Larger syringes (like 5 mL or 10 mL) have coarser markings, making a 0.5 mL dose harder to read precisely and increasing the chance of under- or over-dosing. A very small syringe (0.1 mL) isn’t ideal for a 0.5 mL dose because it can be awkward to use and reads would be very close together, which raises the chance of error. So, the 1 mL syringe offers the best balance of easy readability and appropriate capacity for accurate vaccine dosing.
