Dr. Kavita Patel on why the COVID-19 vaccine is safe


NBC News medical contributor Dr. Kavita Patel joins Weekend TODAY’s Peter Alexander and says the emergency use authorization of a coronavirus vaccine in less than a year “truly is a miracle.” She explains why she thinks no corners were cut in the production of the vaccine. “The shortcut … was not from safety.
