WASHINGTON - As the U.S. continues its mass vaccination effort against the coronavirus, experts say getting children inoculated will be crucial to ending the pandemic and ultimately returning to some kind of normalcy.Children make up about one-fourth of the U.S.
population. Estimates for the country to reach "herd immunity," or widespread resistance to the virus, range between 70% to 85% of the population being vaccinated.The spread of more contagious variants of the virus, which has killed close to 537,000 Americans, has also increased the need for more people to get their shots as soon as possible."If children are 25% of the population, you would either have to vaccinate every single last adult or we have to also vaccinate the children,".
