Figure 1.

Annual incidence rate of the 11 selected vaccine-preventable diseases and six long-studied diseases in China from 1950 to 2018

The blue line in the large chart shows the incidence rate of the 11 vaccine-preventable diseases (VPDs), and the pink line represents the six diseases that have been continually monitored since 1950 in China (here called long-studied diseases: Japanese encephalitis, diphtheria, meningococcal meningitis, measles, poliomyelitis, pertussis). Since the incidence rates of the remaining five diseases were only available after 1990, the two lines overlap before that year. The small chart shows the incidence of the six long-studied diseases from 1990 to 2015.
