Moderna says its low-dose COVID shots work for kids under 6

Moderna’s COVID-19 vaccine works in babies, toddlers and preschoolers, the company announced Wednesday -- and if regulators agree it could mean a chance to finally start vaccinating the littlest kids by summer.

Moderna said in the coming weeks it would ask regulators in the U.S. and Europe to authorize two small-dose shots for youngsters under 6.. The company also is seeking to have larger-dose shots cleared for older children and teens in the U.S.
