Moderna announced promising results on its vaccine on Monday. The company said it produced a “robust immune response” in children ages 6 to 11.

The company said the two-dose vaccine administered in children yielded similar results in children as it did in adults after administering 4,753 patients between the ages of 6 to 11 and looked at two 50 microgram doses 28 days apart. Those who took the vaccine experienced mild to moderate fatigue, headache, fever, and injection site pain.

Moderna says it will submit its data to the Food and Drug Administration and the European Medical Agency “in the near term.”

The Moderna vaccine is currently approved for patients 18 and older.

The FDA still has yet to authorize it for adolescents ages 12 to 17. Pfizer is also working on a vaccine for children ages 5 to 11 as their vaccine has been authorized for adolescents ages 12 to 15 and anyone who is 16 or older.

According to the Centers for Disease Control and Prevention, 66.2% of Americans have received at least one dose of the vaccine with 57.2% being fully vaccinated.

"If all goes well, and we get the regulatory approval and the recommendation from the CDC, it's entirely possible if not very likely that vaccines will be available for children from 5 to 11 within the first week or two of November," Dr. Anthony Fauci said.
