Factors affecting routine immunization coverage among children aged 12-59 months in Lao PDR after regional polio eradication in western Pacific region.

The global poliomyelitis eradication programme had a great impact on routine immunization coverage in Lao PDR: DPT3 increased 23% in 1992 to 56% in 1999; OPV3 27% to 64%. However, after the achievement of regional eradication, coverage became stagnant in accordance with the withdrawal of various sources of financial supports. In place of the former funds, a public-private global partnership began to support EPI.
