Centers for Disease Control and Prevention research finds wearing a surgical mask underneath a cloth mask — a concept known as double masking — can vastly improve the protection for the wearer.
Like many Russians, NPR's Moscow Correspondent Lucian Kim thought long and hard about whether he should get the Sputnik V COVID-19 vaccine. He finally decided to go ahead on Wednesday.
New research found that wearing a cloth mask over a medical mask significantly boosts protection against droplets that can transmit the virus. Knotting the ear loops of surgical masks also helps.
The same electronic systems used to record when patients get a physical or go to the ER are also used to log data when coronavirus vaccines are given. But the systems don't share information easily.
The electronic health record system is complicating the U.S.'s COVID-19 vaccine rollout. NPR's Noel King talks to Dr. Bob Kocher, who has advised California on its virus response, about the issue.
