In celebration of world immunization week, one cannot ignore the great strides China has made to protect over one-fifth of the world’s population from vaccine preventable diseases.  The Chinese government has worked closely with CDC, WHO, UNICEF and other partners as it has addressed this challenge head on with new policies, supplemental immunization activities and successes reaching those most in need of care.  These steps protect not only China’s population from disease, but also protect the U.S. and the rest of the world from the global spread of infectious, vaccine-preventable health threats.
