Because Ruby and Levi Brackett had difficulty keeping track of which vaccine went with which syringe, their dad developed a solution. He purchased 4 rolls of colored electrical tape (red, green, blue and white) for $0.69 each. At vaccination time, they marked each syringe with tape and placed matching colored tape on the corresponding vaccine bottle.

To help them remember the correct way to give the shot they place one stripe for subcutaneous injections and two stripes for intramuscular shots. Even though the needles varied in length, the brightly colored tape stripes are much easier and faster to identify. Both Ruby and Levi now feel more comfortable administering vaccinations and there's less potential for error.
