RESUMO
The article summarizes the scientific evidence related with protection conferred by the 23 valent polysacchar-die vaccine against invasive pneumococcal disease, non bacteriemic pneumococcal pneumonia, and probable pneumococal pneumonia in the elderly. Eider patients with and without risk factors are considered. The impact of herd immunitty conferred by vaccination of children with conjugated pneumococcal vaccine in reduction of penumonia in adults is discussed. Based on this analysis, the Advisory Committee on Immunizations of the Chilean Infectious Disease Society makes recommendations on the most efficient vaccine strategy for reduction of pneumococcal pneumonia in the elderly.
El artículo resume los hallazgos de la evidencia científica en relación a la protección que confiere la vacuna neumocóccica polisacárida 23 valente contra la enfermedad neumocóccica invasora, las neumonías neumocóccicas no bacteriémicas y las neumonías probablemente de etiología neumocóccica en el adulto mayor, estableciendo una categorización entre adultos mayores con factores de riesgo y sin ellos. Se documenta a la vez, el impacto que ha tenido la vacuna neumocóccica conjugada en la población infantil, en reducir las neumonías en el adulto mayor. Basados en la información disponible, el Comité Consultivo de Inmunizaciones de la Sociedad Chilena de Infectología, realiza recomendaciones sobre cuál sería la mejor forma de prevenir las enfermedades neumocóccicas en el adulto mayor.

The article briefly reviews the epidemiology of human papillomavirus (HPV) infection and associated diseases in the world and in Chile and the scientific information of the licensed HPV vaccines: Gardasil® and Cervarix®. Considering the available information, the Consultive Committee of Immunizations of the Chilean Society of Infectious Diseases, summarizes its conclusions and makes recommendations for vaccination against HPV in Chile.

This article briefly reviews the epidemiology of human papillomavirus (HPV) infection and associated diseases globally and in Chile, and the scientific ínformatíon of the licensed HPV vaccines: Gardasil® and Cervarix®. Considering the available information, the Advisory Committee on Immunizations of the Chilean Society of Infectious Diseases recommends vaccination of teenage girls, ideally before initiating sexual actívíty, Le. approximately at the age of 12 to 13 years and vaccination of women of any age if they have not started sexual activity. If women are vaccinated after initiating sexual activity, they should be informed of the lower efficacy of immunization if HPV infection has occurred. Education on responsible sexuality and sexually transmitted diseases should be maintained as a priority. Vaccination should be highly considered for inclusion in the National Immunization Program.

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.
