Why it matters

The cancellation concerns a U.S.-funded research project and raises questions about how vaccine trials involving infants are designed and reviewed. The supplied report does not establish any effect on vaccine availability or public health in the United States.

What happens next

The trial has been cancelled. The supplied report does not say whether the researchers will propose a different study or what review process led to the decision.

Whether the researchers propose a redesigned study
