1st person in US gets experimental coronavirus vaccine

The video discusses the first human trial of an experimental COVID-19 vaccine, funded by the NIH and conducted by Kaiser Permanente. Unlike traditional vaccines, this one uses mRNA to instruct cells to produce a protein found in the SARS-CoV-2 virus, potentially triggering an immune response. This response may help the body fight off a real infection if exposed to the virus later.

What protein does the vaccine aim to make cells produce?

What potential benefit does the vaccine provide if a person is later infected with COVID-19?
