ABSTRACT

El timerosal es un derivado del mercurio utilizado desde 1930 como preservante de vacunas. En las últimas décadas ha sido cuestionada su seguridad, especialmente por la posibilidad de toxicidad neurológica. La revisión de varios estudios realizados en niños que recibieron vacunas que contienen timerosal y la posición de organismos de expertos internacionales en relación al uso de este compuesto en vacunas, permite al Comité Consultivo de Inmunizaciones concluir que no existe evidencia de eventos adversos en lactantes o niños por exposición al timerosal contenido en vacunas rutinarias y, por lo tanto, no habría razón para modificar las actuales prácticas de inmunización en Chile.


Thimerosal is a mercury derivative included in vaccines since 1930 with the aim to prevent microbial contamination. During the last decades, the use of thimerosal has been questioned, specifically because of a potential association with neurotoxicity. After a thorough review of published studies on pediatric use of thimerosal-containing vaccines, and of position papers from international expert groups, the Consultive Committee of Immunizations of the Chilean Society of Infectious Diseases concludes that there is no solid evidence of adverse events associated with the use of thimerosal containing vaccines in infants and children. Therefore, a change in current vaccine practices refererred to thimerosal-containing vaccines is not justified in Chile.
