The University of Pittsburgh School of Medicine is testing a potential vaccine against COVID-19, or officially SARS-CoV-2.
Dr. Louis Falo, of the University of Pittsburgh School, talks about how the vaccine is delivered through a fingertip-sized patch.
Researchers say the vaccine produced SARS-CoV-2 antibodies in mice at quantities thought to be sufficient for neutralizing the virus, although more testing and clinical trials would have to be done.
