Research develop a fingertip-sized patch of 400 tiny needles that deliver vaccine into the skin, where the immune reaction is strongest.The new vaccine can be mass produced and can sit at room temperature until needed, eliminating the need for refrigeration during transport or storage.Researchers in the US say they were able to act quickly because they had laid the groundwork during previous epidemics.
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 [PDF] 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.
Researchers at the University of Pittsburgh School of Medicine say they were able to act quickly because they had laid the groundwork during earlier coronavirus epidemics.
