Andrea Mitchell is joined by Dr. Ashish Jha to discuss vaccine mandates, risks for children under 12 who cannot yet get vaccinated, and why he believes it is "puzzling” that the FDA has not granted full approval for the COVID-19 vaccine, which is causing a "psychological barrier" for companies who may be waiting for full approval before instituting vaccine mandates.
