A National Institutes of Health-funded study led by a team at the Georgia Institute of Technology and Emory University has shown that an influenza vaccine can produce robust immune responses and be administered safely with an experimental patch of dissolving microneedles. The method is an alternative to needle-and-syringe immunization; with further development, it could eliminate the discomfort of an injection as well as the inconvenience and expense of visiting a flu clinic.
“This bandage-strip sized patch of painless and dissolvable needles can transform how we get vaccinated,” said Roderic I. Pettigrew, Ph.D., M.D., director of the National Institute of Biomedical Imaging and Bioengineering (NIBIB), which funded the study. “A particularly attractive feature is that this vaccination patch could be delivered in the mail and self-administered. In addition, this technology holds promise for delivering other vaccines in the future.”
