'No doubt' about the benefits of vaccines

The rates of incidence for dozens of vaccine-preventable diseases last year dropped to a record low in China, thanks to the national immunization program, the Chinese Center for Disease Control and Prevention said.

According to the center, the program has expanded from three vaccines against six diseases when it was introduced in 1978 to 14 vaccines against 15 contagious ones now.

Since the early 21st century, vaccination rates for newborns and children in China have remained steady at more than 90 percent.
