Influenza vaccination hesitancy in five countries of South America. Confidence, complacency and convenience as determinants of immunization rates.

Introduction: Influenza morbidity and mortality are significant in the countries of South America, yet influenza vaccination is as low as 56.7% among pregnant women, reaching 76.7% of adults with chronic diseases.

Risk of dengue virus infection according to serostatus in individuals from dengue endemic areas of Mexico.

The variability in the host immune response directed against dengue virus (DENV) has demonstrated the need to understand the immune response associated with protection in incident infection. The objective was to estimate the association between serostatus and the risk of incident DENV infection. We used a prospective study from 2014 to 2016 in the localities of Axochiapan and Tepalcingo, Morelos, Mexico.

The importance of confidence, complacency, and convenience for influenza vaccination among key risk groups in large urban areas of Peru.

Influenza vaccination has been available under Peru's national immunization program since 2008, but vaccination coverage has decreased lately. Surveys and focus groups were conducted among four risk groups (pregnant women, mothers of children aged <6 years, adults with risk factors, and adults aged ≥65 years) to identify factors affecting influenza vaccine hesitancy in Peru. The 3Cs model (Confidence, Complacency, and Convenience) was used as a conceptual framework for the study.
