Moderna says its COVID-19 shot works in kids as young as 12

Moderna says its COVID-19 vaccine strongly protects kids as young as 12, a step that could put the shot on track to become the second option for that age group in the US.

With global vaccine supplies still tight, much of the world is struggling to vaccinate adults in the quest to end the pandemic. But earlier this month, the US and Canada authorized another vaccine — the shot made by Pfizer and BioNTech — to be used starting at age 12.

Moderna aims to be next in line, saying it will submit its teen data to the US Food and Drug Administration and other global regulators early next month.

The company studied more than 3,700 12- to 17-year-olds. Preliminary findings show the vaccine triggered the same signs of immune protection in kids as it does in adults, and the same kind of temporary side effects such as sore arms, headache and fatigue.

There were no COVID-19 diagnoses in those given two doses of the Moderna vaccine compared with four cases among kids given dummy shots. In a press release, the company also says the vaccine appeared 93% effective two weeks after the first dose.

While children are far less likely than adults to get seriously ill from COVID-19, they represent about 14% of the nation’s coronavirus cases. At least 316 have died in the US alone, according to a tally by the American Academy of Pediatrics.
