Researchers at the University of Pittsburgh have tested a potential vaccine for COVID-19 in mice, and it was successful in generating antibodies to fight the coronavirus within two weeks. The vaccine, called PittCoVacc - short for Pittsburgh Coronavirus Vaccine, was delivered through a band-aid sized patch with micro-needles. Through previous research, they found that a particular spike protein is important for inducing immunity against the virus. They used lab-made pieces of viral protein to build immunity and said that it works the same way as current flu shots. The tiny needles deliver the spike proteins into the skin, where the immune reaction is strongest. The team hopes to advance to human trials faster than the usual time-frame.
