Pfizer is launching a trial studying its vaccine in children aged six months to 11 years.
The first phase will test three different dosages of the vaccine.
Phases 2 and 3 will evaluate the vaccine's safety and effectiveness.
Pfizer says at the six-month follow-up visit, those who received the placebo will be given the opportunity to get the vaccine.
The vaccine is currently authorized for ages 16 and older.
