Health officials warn of new flu strain outbreak

With flu season already well underway, health experts are tracking a new flu strain that has caused outbreaks in the U.K. and Canada. The new strain first emerged over the summer, four months after this year's flu vaccine was made. It is unclear if the new strain has made its way to the U.S. Dr. Amesh Adalja, senior scholar at the Johns Hopkins Center for Health Security, joined "The Daily Report" to discuss.
