The Importance of Vaccines Throughout History

Season 2021 Episode 3139 | 2m 20s

Nearly 9 million Americans have received their first dose of the vaccine, while President-elect Biden received his second dose today.

Now an infectious disease expert himself, Peter Salk joins the show to discuss the importance of vaccines, then and now.
