China to start vaccinating children to age 3 as cases spread
China becomes one of the very few countries in the world to start vaccinating children that young against the virus. Cuba, for one, has begun a vaccine drive for children as young as 2. The U.S. and many European countries allow COVID-19 shots down to age 12, though the U.S. is moving quickly toward opening vaccinations to 5- to 11-year-olds.
