This is a painless microneedle vaccine kit which consists of a microneedle vaccine patch and a syringe. We designed the vaccine patch as a little red flower, and the syringe as a seal. The process of vaccination is like getting a little red flower as a reward after a child gets an injection. The vaccine patch needs to stay on the arm for 15 minutes for the medicine to enter the body. The red flower shape makes children more willing to keep the patch on the arm. This product eliminates the fear of needles in children and enhances the benign interaction between children and medical personnel.
