US Gives Favorable Review to Second COVID-19 Vaccine VOA News As U.S. hospitals ramped up COVID-19 vaccinations Tuesday with the first vaccine approved for emergency use, federal regulators issued a favorable review of a second vaccine needed to combat the country's worsening crisis. The Food and Drug Administration said its preliminary analysis of a vaccine developed by Moderna and the National Institutes of Health confirmed its safety and effectiveness. The FDA's review moves the Moderna vaccine closer to regulatory authorization and comes as U.S. hospitals increased vaccinations with the shot developed by Pfizer and BioNTech, which the FDA cleared for emergency use last week. .
