ABSTRACT

Seroprevalence studies are designed in population samples to assess the level and distribution of immunity induced by natural infection of certain infectious agents or by immunization against them. The purpose of the 2nd Seroprevalence Study in Spain is to assess the prevalence and distribution of immune status against vaccine-preventable diseases and generated by natural infection by other microorganisms. Pathologies specifically included in the study are: poliomyelitis, diphtheria, tetanus, pertussis, measles, rubella, mumps, varicella, invasive meningococcal disease by serogroup C, hepatitis A, hepatitis B, hepatitis E, hepatitis C and HIV. The study has a similar design of that conducted in 1996, as it is a descriptive cross-sectional study in resident population of 2 to 80 years of age in Spain. Two-stage conglomerate sampling was carried out on the population aged 2 to 80 years living in Spain, with an initial sample size of 10,000 people. The methodology of the study is described in this article.


Los estudios de seroprevalencia se elaboran en muestras poblacionales con el fin de investigar el nivel y distribución de la inmunidad inducida por infección natural de determinados agentes infecciosos o por vacunación frente a los mismos. El 2º Estudio de Seroprevalencia en España tiene el objetivo de estimar la prevalencia y distribución del estado inmune frente a las enfermedades inmunoprevenibles y de la generada por infección natural por otros microrganismos. En concreto, las patologías incluidas en el estudio son: poliomielitis, difteria, tétanos, tosferina, sarampión, rubéola, parotiditis, varicela, enfermedad meningocócica invasora por serogrupo C, hepatitis A, hepatitis B, hepatitis C, hepatitis E e infección por virus de la inmunodeficiencia humana (VIH). Para ello, se ha diseñado un estudio similar al realizado en 1996, observacional de tipo transversal en la población residente en España de 2 a 80 años de edad. Se ha realizado un muestreo por conglomerados bietápico de la población de 2 a 80 años residente en España, con un tamaño muestral inicial de 10.000 personas. En este artículo se describe la metodología utilizada en la realización del estudio.

ABSTRACT

Los estudios de seroprevalencia se realizan sobre una muestra de problación con el fin de investigar el nivel y distribución de la inmunidad inducida por infección natural de determinados agentes infecciosos o por vacunación frente a los mismos.

ABSTRACT

Pertussis continues to be an important cause of morbidity and mortality in children too young to be fully protected despite high vaccination coverage. This has been attributed to waning immunity in older people, leading to the development of strategies to increase levels of immunity. A systematic review was conducted to assess the clinical and cost effectiveness of four population-based strategies for pertussis booster vaccination: single booster at 12-24 months old, single pre-school booster, single adolescent booster and multiple boosters in adulthood every 10 years. Electronic databases and Internet resources were searched to June 2006. Nine observational studies, four mathematical models and eight economic evaluations were included, evaluating four different strategies. Strong evidence to recommend any of these strategies was not found.
