Dr. Jha on Pfizer vaccine: 'We should not have doses sitting around waiting for instructions'

Dr. Ashish Jha joins Andrea Mitchell to discuss Pfizer vaccine distribution and the endorsement of the FDA panel on the Moderna vaccine. "The vaccine has two benefits: it protects me when I get vaccinated, but it should protect people around me because I should become less likely to spread the virus." Dr. Jha then added, "until recently we didn't know if it did that second part. Now we have data that shows that it does. And that’s really, really important.”
