The Lao Experience in Deploying Influenza A(H1N1)pdm09 Vaccine: Lessons Made Relevant in Preparing for Present Day Pandemic Threats.

The Lao PDR, as did most countries of the Mekong Region, embarked on a pandemic vaccine initiative to counter the threat posed by influenza A(H1N1)pdm09. Overall, estimated vaccine coverage of the Lao population was 14%, with uptake in targeted health care workers and pregnant women 99% and 41%, respectively. Adverse Events Following Immunization accounted for only 6% of survey driven, reported vaccination experiences, with no severe consequences or deaths. Public acceptability of the vaccine campaign was high (98%). Challenges to vaccine deployment included: 1) no previous experience in fielding a seasonal influenza vaccine, 2) safety and efficacy concerns, and 3) late arrival of vaccine 10 months into the pandemic. The Lao success in surmounting these hurdles was in large measure attributed to the oversight assigned the National Immunization Program, and national sensitivities in responding to the avian influenza A(H5N1) crisis in the years leading up to the pandemic. The Lao "lessons learned" from pandemic vaccine deployment are made even more relevant four years on, given the many avian influenza strains circulating in the region, all with pandemic potential.

UXO victims and health status of populations living in Xiengkhuang Province, Lao PDR: A household-based survey.

During the Vietnam War from 1964 to 1973, over 2 million tons of bombs were dropped on Laos. Approximately 30% of the bombs did not explode and have posed a continued threat to civilians throughout the country. Approximately 200 casualties per year have been reported nationwide. Therefore, we conducted a household survey to better understand magnitude of UXO victims, accessibility to the MCH services and child healthcare seeking behaviors of the population in the Xiengkhuang province. The household-based survey was carried out in February 2006 among 6 of 541 villages. 283 household representatives were interviewed. The cumulative number of UXO victims identified from 1973 to 2005 was 45 casualties, of which 9 (20.0%) occurred in the year 2005. 37.5% reported knowledge of danger zones for UXO contamination. Among the 91 children under the age of 5 years, households on average reported 1.7 episodes per year for diarrhea, 2.7 for respiratory disease, 2.3 for fever and 1.7 for measles. 69.4% of children under five were completed the routine immunization program, 62.6% of mothers used ANC service for their most recent pregnancy, 58.2% accessed family planning services, and 28.6% delivered their most recent child at a healthcare facility. UXO victims in the targeted villages sharply increased in 2005. Insufficient knowledge about UXO danger and MRE seems to be a central factor in the high rate of UXO-associated accidents. Diarrhea, respiratory disease and measles remained health problems for children under 5 years. MCH services utilization were higher than Laos nationally.
