Initial tests in mice of a potential COVID-19 vaccine delivered via a fingertip-sized patch have shown it can induce an immune response against the new coronavirus at levels that might prevent infection, U.S. scientists said on Thursday.
Researchers around the world are working to develop potential treatments or vaccines against the respiratory disease that has killed nearly 47,000 people and infected almost a million in just a few months.
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 Pittsburgh researchers 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 against COVID-19 lasts.
