The vaccine created in the United States works on mice. Will it be on humans?


Initial tests in mice of a potential Covid-19 vaccine administered via a fingertip patch have shown that it can induce an immune response against the new coronavirus at levels that could prevent infection, the researchers said on Thursday. American scientists.
When tested in mice, the prototype vaccine – which the researchers called PittCoVacc – generated what they described as “a wave of antibodies” against the new coronavirus in two weeks. Researchers at the University of Pittsburgh School of Medicine have warned that, since animals have not been followed for a very long time, it is too early to say if and for how long the immune response lasts. The team said it hopes to start testing the vaccine on people in the coming months.
The patch of 400 tiny finger-sized needles, made of sugar and advanced protein, is designed to deliver pieces of advanced protein into the skin, where the immune response is strongest.
