Moderna says a study in kids 6 to 11 found two doses of the company's COVID-19 vaccine given 28 days apart produced a strong antibody response.
The study, conducted in collaboration with the National Institutes of Health, used shots containing a 50 microgram dose of the vaccine, half the dose of the Moderna shots authorized for adults. More than 4,700 children ages 5 to 11 took part in the study.
The most common side effects were fatigue, headache, fever and pain at the site of injection. The company says the analysis showed a "favorable safety profile."
