The United States saw more COVID-19 cases in November than in any other month during the pandemic. And as the virus increases during the Christmas season, health officials have urged the public to avoid travel and large family gatherings that could spread it. But hope is on the horizon. On December 8, the UK became the first nation to begin vaccinating its citizens with a fully approved and licensed COVID-19 vaccine. The United States also began distributing the same vaccine, developed by Pfizer and BioNTech. Early data on coronavirus vaccines from Pfizer and Moderna suggest that both are safe and highly effective, each preventing 95% of symptomatic infections in people who volunteered to test them, according to the companies. | PHOTOS | 2020 in pictures: December | CNN
