RESUMO
Background@#Outbreaks of vaccine preventable-disease control and elimination are impeded by impaired focal vaccination uptake. Therefore, we aimed at assessing vaccination uptake and comparing with passive surveillance (PS) report at village level.@*Methods@#A community-based cross-sectional survey was conducted in the villages covered by two health centers in Bolikhamxay province, including non-Hmong and Hmong ethnic groups. Data collection was conducted by interviewing mothers or caregivers of children aged 6 to 23 months. The vaccination status was identified by vaccination cards, and compared with PS report at village level, which was collected from health centers. The Pearson’s chi-square test was used to compare these proportions, and pairwise correlation was used for the correlation of observed vaccination coverage.@*Finding@#Sixteen villages were included, nine were from Luk52 health center area and 7 from Namkhou health center area. There was a significantly strong correlation for pentavalent pneumococcal conjugate vaccine, Japanese encephalitis, Measles and Rubella and full immunization coverage compared to others. This correlation was not observed in the non-Hmong population. Amongst non-Hmong, the recorded coverage was lower in PS than in the survey regardless of type of vaccine. In contrast, amongst Hmong most vaccines had higher recorded coverage in PS than in the survey except Bacillus Calmette–Guérin (BCG) and hepatitis B at birth dose. MR and JEV vaccine, commonly given at the same time, were the only one that did not have significantly different coverage between PS and the survey (p<0.334).@*Conclusion@#The mis-estimatation of immunization coverage from the PS reporting system highlights further research needed to determine a better indicator of village-level vaccination coverage, but measles could be an indicator of prioritizing the settings.
RESUMO
Background: Infectious diseases are a major cause of morbidity and mortality in children. One of the most cost-effective and easy methods for child survival is immunization. The objective of study was to assess the immunization coverage in the rural area of Dhule.Methods: A community based cross-sectional study was conducted by using WHO 30x7 cluster sampling technique in Primary Health Centre, Kheda catchment villages among children aged 12-23 months on the day of survey. The total sample size was found out to be 210. Identification of clusters was done as per WHO manual on 30×7 cluster survey. Interviews were conducted as per a structured interview format in households with eligible children. Data feeding was done in MS Excel sheet.Results: Full immunization coverage (FIC) was found out to be 58.6%. Drop-out rate was calculated to be 22.95%. The main reason for not completing the immunization was unaware to return for subsequent vaccine doses.Conclusions: Coverage evaluation of vaccines was found out to be 58.6%. Drop-out rate is high.
RESUMO
A coverage evaluation survey was conducted in Mandya and Koppal districts of Karnataka state following the Japanese Encephalitis (JE) vaccination campaign. The purposes of the survey were to assess coverage of children in target age group by JE vaccination and to assess adverse events following immunisation against JE, the knowledge of health care providers and community about JE & mass vaccination for JE. The study design consisted of both quantitative and qualitative methods. The quantitative data was used to know the coverage levels for children. The qualitative data collected through interviews of head of the family in the sample households, selected health care workers using a structured pretested questionnaire. The standard cluster sampling method was used for selecting the sample of children to be evaluated. In Mandya district the evaluation showed 92 % coverage in the selected sample of 313 children against the reported 83.85 %. In Koppal district the evaluation showed 70 % coverage, among the selected sample of 251 children, against the reported coverage of 69.8 %. The incidence of adverse events was 4% in Mandya sample and 6.37 % in Koppal sample. In Mandya district, about 42 % of households had knowledge of JE. About 68 % of households had prior knowledge of the immunization day. In Koppal district, the survey has revealed that only 19.85 % of the heads of household had the knowledge of JE and 48.53% had the knowledge of JE vaccination before the day of vaccination campaign.
