When Elmo was nervous about getting a shot, he didn't enlist any old doctor for moral support. In a new video produced by the Daily Dot, U.S. Surgeon General Vivek Murthy teaches the "Sesame Street" favorite about the importance of getting vaccinations. After explaining the health benefits of being vaccinated, Murthy suggests that Elmo sing a song to take his mind off the (slight) pain Elmo might experience.
