Researchers from Emory University and the Georgia Institute of Technology recently presented a new vaccine-delivery patch based on hundreds of microscopic needles that dissolve into the skin. The new technology could allow persons without medical training to painlessly administer vaccines, while providing improved immunization against diseases such as influenza. The hollow microneedle, fabricated from stainless steel, penetrates the white of the eye – called the sclera – to reach a unique location underneath it called the suprachoroidal space This simplifies immunization programs by eliminating the use of hypodermic needles and their “sharps” disposal and re-use concerns. This technique can be easily applied, thus allowing could self-administration of vaccine during pandemics.
