Moderna's Covid-19 vaccine could become the second shot okayed for adolescent use in the European Union as regulators recommend to approve it for 12- to 17-year-olds, reports Reuters.

Use of the vaccine, Spikevax, will be the same in adolescents as in people over 18, the European Medicines Agency (EMA) said, adding the shot produced a comparable antibody response to that seen in 18- to 25-year-olds.

Vaccinating children has been considered important for reaching herd immunity and in light of the highly contagious Delta variant. Moderna in May said its vaccine was found to be safe and effective in teenagers.

The EMA said the two-dose vaccine is given four weeks apart, and its human medicines committee's recommendation was based on a study of 3,732 participants.
