Polio outbreak in Gaza: new vaccination campaign

A polio case was reported in Gaza for the first time in 25 years. A 10-month-old boy contracted the disease, and is now paralyzed in the leg. The U.N. health agency is launching a vaccination campaign on Sunday. The goal is to vaccinate 640,000 Palestinian children against polio. Dr. Peter Chin-Hong, infectious disease expert, joins LiveNOW from FOX to explain the dangers of the disease, and the importance of the vaccinations.
