Moderna vaccine ships

A second vaccine has begun to roll out in the U.S. less than two days after it earned emergency use authorization from the Food and Drug Administration. The vaccine, developed by Moderna and the National Institutes of Health, began the distribution process Sunday as it was shipped out of a Memphis-area distribution center. First shots of the Moderna vaccine are expected to be given Monday, one week after the first inoculations of Pfizer’s vaccine. The first wave of Pfizer and Moderna shots are nearly all going to health care workers and residents of long-term care homes.
