On Monday, the biotech company Moderna announced its new coronavirus vaccine appears to be 94.5% effective, based on results from clinical trials.
This came a week after Pfizer announced its vaccine appears to be effective, too.

The Atlanta-based Centers for Disease Control and Prevention asked states to submit their plans for distribution in early November.
Shortly after, ProPublica reviewed each state’s plan.
