Moderna Inc. plans to double enrollment in a trial of its Covid vaccine in children under age 12, following a request from U.S. regulators to collect additional safety data.

Moderna’s study will enroll an estimated 13,275 participants ages 6 months up to 12 years old, according to a listing on the clinicaltrials.gov website. In a post from late July, the Cambridge, Massachusetts-based company said it would seek to enroll about 7,000.
