Nearly 300,000 children under 5 have received COVID-19 shots in the two weeks since they became available, a slower pace than for older groups. But the White House says that was expected for the eligible U.S. population of about 18 million kids.
The Centers for Disease Control and Prevention was to publish initial data on shots for the age group later Thursday, reflecting doses administered since regulators authorized them on June 18. The first vaccinations didn't begin until several days later because the doses had to be shipped to doctors' offices and pharmacies.
