Why is the time between dose one and two for 5 to 11-year-olds eight weeks, not the 21 days used in the clinical trials?

Question: 

Why is the time between dose one and two for 5- to 11-year-olds eight weeks, not the 21 days used in the clinical trials?

Answer: 

The eight-week interval in youth and adults has resulted in a stronger immune response, better protection against COVID-19 infection, and lower risk of myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining around the heart). It is expected that it will be the same for 5 to 11-year-olds. In BC, the preferred interval between dose one and two is eight weeks for both mRNA vaccines for children.
