Despite the recommendations of universal flu vaccine, influenza continues to be a major cause of illness leading to significant morbidity and mortality. Having the option of a flu vaccine that can be easily and painlessly self administered could help to increase coverage and protection.

Researchers at Georgia Tech,USA have developed exactly this- a self administered painless vaccine skin patch containing microscopic needles that could replace flu shots.The patch is embedded with100 microscopically small, dissolvable micro-needles that contain the vaccine.when the patient sticks the patch to the skin,the micro-needles penetrate the skin painlessly and the vaccine is absorbed.

The researchers are now working to develop micro-needle patches for use with other vaccines, including measles, Rubella and polio.
