Many recipients of Taiwan's domestically made Medigen vaccine do not feel much pain during the injection due to the needle are "ultra thin."
Taiwan President Tsai Ing-wen became the first person to receive the Medigen shot and she said that she "didn't feel anything."
The Medigen doses are being delivered with 25-gauge "ultra-thin" needles. The outer diameter of the needles is only 0.02 inches with an inner diameter of 0.009 inches.
This enables the vaccine to be injected into muscle while inflicting minimal damage to body tissues and causing little pain.
The Medigen doses are being packaged in single-use syringes. The inclusion of the vaccine in the single-use syringes eliminates the possibility of contamination from separate packaging.
Medigen, whose Chinese name literally means "high-end," the vaccine was by Medigen Vaccine Biologics Corp., it was given emergency approval by regulators in July using a shortcut that prompted fierce opposition from parts of Taiwan’s medical and scientific community.
