“…In the study of the medical school in Medellín, only 77% know the number of doses that are part of the complete vaccination scheme. 12 In the present study, 64.6% know how to define a biological risk accident, and 24.6% report having suffered a biological risk accident. In the study carried out on nursing students, only 52.7% of those surveyed knew all the guidelines to follow in the event of a puncture and, according to the results of the survey, only 4.7% adopted sufficient measures to prevent contagion.…”

“…Based on these experiences, a population seroprevalence study was conducted in 2009 in Medellín, which estimated the prevalence of antibodies in the population (26)(27)(28)(29)(30) and obtained detailed information on the history of vaccination and the biological and social factors that could influence the presence of antibodies and guide vaccination policies based on the evidence of local epidemiology, as well as the use of mathematical modeling to estimate the critical proportion of immunity and the basic and effective reproductive number indicating the level of achievement of disease elimination (27,31). The percentage of participation in this population-based seroprevalence study was 88,5% (26) during a time of armed conflict in the city, which implied high costs, greater efforts and additional time.…”

Introduction: Serological surveillance (serosurveillance) provides the most direct measure of herd immunity of vaccine-preventable diseases. Little is known about the opportunities and challenges of serosurveillance experiences, particularly pertussis.Objective: To describe the process of serosurveillance for vaccine-preventable diseases with an emphasis on the experience of pertussis in the metropolitan area of Antioquia (Valle de Aburrá) in 2015 and 2016 and analyze the contributions and challenges for its sustainability.Materials and methods: We described the planning and conduction of serosurveillance of pertussis antibodies of mothers and in the umbilical cord at the time of delivery in eight hospitals based on random sampling and their capacity to advance the serosurveillance periodically. We compared the contributions and the challenges of this experience with other probabilistic and non-probabilistic programs.Results: We achieved the participation of hospitals and mothers respecting the delivery care process. We established a serum bank following ethical and technical guidelines. This program based on the random selection of hospitals and mothers has enabled the estimation of antibodies prevalence in mothers and in the umbilical cord, which has been possible given the high coverage of hospital care during childbirth at a lower cost and fewer risks than a population-based survey in conflictive areas. The main challenges for the sustainability of this program are the creation of stable jobs and access to funding and legal and methodological long-term frameworks.Conclusions: Hospital serosurveillance as described is an option to monitor the impact of vaccination on the population. Our experience could be reproduced in other regions under similar conditions if the above-mentioned challenges are solved.
