Group to map way out of vaccine morass

China has set up a national work group for immunization planning that will suggest ways to ensure vaccines are safe, the head of the Chinese Center for Disease Control and Prevention said on Monday.

The work group, led by a vice-minister of health, will analyze all incidents involving vaccine safety over the past few years to find the root sources of problems, Gao Fu, head of the center, said at a news conference. He didn't name the minister.

"Vaccines made in China are some of the best in the world," said Gao, who is also a member of China's top political advisory body. "We should have no doubt about the role of vaccines in disease prevention or the quality of vaccines made in China."
