Researchers develop new microneedle array combination vaccine delivery system

In parallel to their current work on a potential coronavirus vaccine, researchers at the University of Pittsburgh School of Medicine have developed a new vaccine delivery system for vaccines using live or attenuated viral vectors: a finger-tip sized patch that contains 400 tiny needles, each just half of one millimeter. Their progress is reported in the Journal of Investigative Dermatology, published by Elsevier.
