What’s the delay?

Dear Editor,
With schools reopening across the country, why is there still no vaccine ready for children ages 5 to 11 years of age? What is the FDA waiting for? It should have been working on this for the last several months.
Our children need to be protected in the classrooms, and time is of the essence. It has been reported that the FDA may have an approved vaccine later this year, why not within the next couple of weeks?
Put the medical pedal to the metal and get this vaccine approved for these kids.
Sincerely,
John Amato
