Stretching the skin could enable vaccines to be given without a needle
PositiveScience

A new breakthrough in vaccine administration could change the way we receive immunizations. Researchers have discovered that using a suction device to stretch the skin enhances its permeability and activates immune cells, potentially allowing vaccines to be delivered topically without needles. This innovation not only promises to make vaccinations less painful but could also improve accessibility and compliance, especially for those who fear needles.
