In 2011, as part of VWA, Venezuela targeted children aged less than 6 years in 25 priority border municipalities using social mobilization to increase institution-based vaccination.
Such concerns were part of the reason that border municipalities were prioritized during VWA 2011 in Venezuela, as the initiative represents one strategy to identify those children with incomplete schedules and improve coverage.
The VWA 2011 campaign in Venezuela included targeting children aged less than 6 years of age who were eligible for one or more vaccine doses in the national schedule (Table 1), with emphasis on those who lived in one of 25 high risk border municipalities, selected based on reported low coverage the year prior.
Our evaluation provided important information regarding the implementation and outcome of VWA 2011 in one border municipality, and provided insight into the performance of EPI in this challenging and dynamic area.
While access to vaccination services was beyond the scope of this survey, it merits further examination, especially in a border municipality such as Bolivar which has high population mobility.
We conducted a survey in one border municipality of Venezuela to evaluate the outcome of VWA 2011 and provide a snapshot of the overall performance of the routine EPI at that level.
To account for retail locations outside of the city of Toronto in bordering municipalities, additional fieldwork was completed to ensure all food outlets were within 1 km of the residential addresses that were included in the analysis.
The seroconversion rate in these municipalities peaked on August 27, when 4 chickens were seropositive, and remained high until September 4. Seroconversion was detected for 10 more birds in the same and other bordering municipalities, all near the rice-growing region and flood plain of the Axios, Loudias, and Aliakmonas Rivers.
The study was carried out in two areas of Colombia: the locality of Kennedy (Bogotá, D.C). and the bordering municipality of Soacha; and three areas in Brazil: the state capital of Pernambuco, Recife, an adjacent municipality, Paulista, and a municipality of the state's interior, Caruaru.
It is located 344 km southwest of Rio Branco, and it borders the municipality of Brazil to the east, the cities of Iñapari Peruu) and Bolpebra (Bolivia) to the south, and the municipality of Sena Madureira to the north.
