Dr. Anderson said that vaccine makers could have started running trials for children over the summer, as soon as they had gotten good Phase 2 results from adults. Whenever these trials do start, it could take upward of a year to get vaccines for Covid-19 ready for children. A couple more months might pass while the vaccine developers give a low dose to a small group of kids. Only then would vaccine developers start a new trial with a higher dose. These tests would likely start with older children, before researchers could shift down to kids between 3 and 8.
