Scientists developing coronavirus vaccine delivered via fingertip-sized patch

A fingertip-sized patch could be a potential vaccine for coronavirus, researchers say. Scientists suggest that when tested in mice, it produced antibodies specific to Covid-19 in quantities thought to be sufficient for neutralising the virus.The vaccine is described in a paper published in EBioMedicine, which is published by The Lancet, and is thought to be the first to be reviewed by other scientists.
