By Rachel Fadem, CNN(CNN)-- Elmo, everyone's favorite red Muppet, has received the Covid-19 vaccine. "I learned that Elmo getting vaccinated is the best way to keep himself, our friends, neighbors, and everyone else healthy and enjoying the things they love." Covid-19 vaccines are now available for children under 5, and parents may have some questions, said Jeanette Betancourt, senior vice president of US social impact at Sesame Workshop. The US Food and Drug Administration gave emergency use authorization for the Moderna and Pfizer/BioNTech Covid-19 vaccines to include children as young as 6 months earlier in June. While Wen was eager to get her children vaccinated, she knows a lot of parents are on the fence.
