Initial tests in mice of a potential Covid-19 vaccine delivered via a fingertipsized patch have shown it can induce an immune response against the new coronavirus at levels that might prevent infection, US scientists said on Thursday.
When tested in mice, the prototype vaccine — which the researchers have called PittCoVacc — generated what they described as “a surge of antibodies” against the new coronavirus within two weeks. The researchers from University of Pittsburgh School of Medicine cautioned that because the animals have not been tracked for very long as yet, it is too early to say whether and for how long the immune response lasts.
The team said they hope to start testing the vaccine on people in the next few months. The fingertip-sized patch of 400 tiny needles, made out of sugar and the spike protein, is designed to deliver the spike protein pieces into the skin, where the immune reaction is strongest.
