RESUMO

[RESUMEN]. El Programa de Inmunización de Cuba se creó en 1962 como resultado de las transformaciones políticas, económicas y sociales iniciadas en 1959, cuando las enfermedades transmisibles — entre ellas las prevenibles por vacunas— eran la principal causa de morbilidad y mortalidad en la población infantil. Su organización y ejecución ininterrumpida han permitido que seis enfermedades, dos formas clínicas graves y dos complicaciones graves estén eliminadas, y las restantes mantengan tasas de incidencia y mortalidad que no constituyen un problema de salud. Anualmente, en Cuba se administran, en promedio, 4 800 000 dosis de vacunas simples o combinadas que protegen contra 13 enfermedades, incluida una pentavalente cuyos cinco componentes se producen en el país. La vacunación antipoliomielítica oral en la campaña de 1962 fue la primera experiencia en la Región de las Américas con participación comunitaria e intersectorial y Cuba, el primer país en eliminar la enfermedad. Resultados recientes de investigaciones cubanas han incidido en el Programa Mundial de Erradicación. La vacunación universal antihepatitis B a las 24 horas después del nacimiento se cumplió 19 años antes de la meta fijada por la OMS empleando una vacuna nacional. En Cuba, la vacunación es gratuita, de acceso universal, está integrada en la atención primaria de salud, y el compromiso y la voluntad política con la salud de la población se vehiculizan mediante un sistema de salud integral. La información y la vigilancia epidemiológica son sistemáticas, confiables y sensibles. Se alcanzan coberturas de vacunación por encima de 98% en todas las vacunas y la población tiene un nivel inmunitario alto.

[ABSTRACT]. The Immunization Program of Cuba was created in 1962 as a result of the political, economic and social transformations initiated in 1959, when communicable diseases —among them those preventable by vaccines— were the main cause of morbidity and mortality in children. Its organization and uninterrupted implementation allowed that six diseases, two serious clinical forms and two serious complications were eliminated, and the remaining ones have incidence and mortality rates that do not represent a health problem. In Cuba, an average of 4.8 million doses of simple or combined vaccines are administered annually protecting against 13 diseases, including a pentavalent vaccine whose five components are produced in the country. Oral polio vaccination in the 1962 campaign was the first experience in the Region of the Americas with community and intersectoral participation, and Cuba was the first country to eliminate the disease. Recent results of Cuban research have influenced the World Eradication Program. The universal vaccination against hepatitis B at 24 hours after birth was achieved 19 years before the goal set by the World Health Organization using a national vaccine. In Cuba, vaccination is free and it is integrated into primary health care, with universal access. The commitment and political will to the health of the population is conveyed through a comprehensive health system. Information and epidemiological surveillance are systematic, reliable and sensitive. Vaccination coverage is above 98% for all vaccines and the population has a high immune level.

Sua organização e execução ininterrupta permitiram que seis doenças, duas formas clínicas graves e duas complicações graves sejam eliminadas, e as demais mantêm incidência e taxas de mortalidade que não constituem um problema de saúde. Anualmente, em Cuba, uma média de 4,8 milhões de doses de vacinas simples ou combinadas são administradas que protegem contra 13 doenças, mesmo uma vacina pentavalente cujos cinco componentes são produzidos no país. A vacinação oral contra a poliomielite na campanha de 1962 foi a primeira experiência na Região das Américas com participação comunitária e intersetorial, e Cuba foi o primeiro país a eliminar a doença. Resultados recentes da pesquisa cubana influenciaram o Programa Mundial de Erradicação. A vacinação universal contra a hepatite B às 24 horas após o nascimento foi completada 19 anos antes do objetivo estabelecido pela Organização Mundial da Saúde usando uma vacina nacional. Em Cuba, a vacinação é gratuita e o acesso universal, e a vacinação é integrada na atenção primária de saúde. O compromisso e a vontade política para a saúde da população são transmitidos através de um sistema de saúde abrangente. A informação e a vigilância epidemiológica são sistemáticas, confiáveis e sensíveis. A cobertura de vacinação é superior a 98% em todas as vacinas e a população possui alto nível imune.

RESUMO

Introducción: la vacuna contra la difteria, la tos ferina (células enteras) y el tétanos que protege contra estas enfermedades, inició su uso en la década de 1940, logró una disminución considerable de estas enfermedades. Pero también, surgieron numerosos eventos asociados a esta vacuna. Uno de ellos es el Episodio de Hipotonía e Hiporreactividad, reportado con menor frecuencia, a las vacunas contra Haemophilus influenzae tipo b y la hepatitis B. Es un evento poco conocido y raro. Objetivo: mejorar el conocimiento sobre esta entidad. Métodos: se realizó un estudio observacional retrospectivo de los Episodio de Hipotonía e Hiporreactividad (según niveles de certeza diagnóstica), reportados durante 2012 y 2013 por el médico de familia al sistema de vigilancia de eventos adversos, procedentes de todas las provincias. Resultados: fueron reportados 27 Episodio de Hipotonía e Hiporreactividad. El 92,6 por ciento correspondió a la vacuna pentavalente, para una tasa de 3,2 x 105 Dosis Aplicadas. El 74 por ciento se notificaron en las primeras 12 horas. Se observó con mayor frecuencia después de la primera dosis, para un 48 por ciento y el 85,4 por ciento ocurrió en los menores de 6 meses. La fiebre, el llanto persistente, los vómitos, el decaimiento y la somnolencia fueron los síntomas asociados con esta entidad. Conclusiones: la vigilancia de este episodio ha permitido conocer el tiempo de aparición después de aplicar la vacuna, dosis, edad y si está asociado con otros síntomas. Constituye un primer acercamiento a este evento, para mejorar su conocimiento, lo cual permitirá continuar con la seguridad y confiabilidad del Programa Nacional de Inmunización en Cuba(AU)

RESUMO

Introducción: en abril de 2009, en México y Norteamérica, un nuevo virus fue identificado como causa de enfermedad respiratoria, el cual se expandió rápidamente a otros países. El 11 de junio de 2009 la Organización Mundial de la Salud notificó casos en 74 países y territorios, en 2 de sus regiones. Esta transmisión elevada y sostenida de este virus en el mundo, propició que se estableciera la fase 6 o de pandemia, lo cual indicó que la situación implicaba diseminación y no mayor gravedad. Objetivos: reportar los eventos conocidos o nuevos tras la aplicación de la vacuna A (H1N1) Pandemrix, identificar los eventos más frecuentes en las embarazadas e investigar de inmediato los eventos severos asociados. Métodos: se diseñó un estudio descriptivo prospectivo para caracterizar los eventos adversos a la vacuna Pandemrix, reportados en todo el país desde el Primero de abril hasta el 30 de junio de 2010. Se vacunaron 1 123 526 personas y se cubrió 100 por ciento de las embarazadas. Resultados: de la vigilancia activa desarrollada en el país se reportaron 5 763 síntomas y signos en 3 401 personas (615 reportes en embarazadas). La tasa general de reportes fue de 302,7 x 100 000 dosis aplicadas. Los eventos adversos: fiebre, cefalea, dolor, inflamación y enrojecimiento en el sitio de inyección, decaimiento, artralgia, manifestaciones alérgicas, vómitos y náuseas como síntomas más frecuentes. Estos 10 síntomas y signos representan 79,1 por ciento del total de eventos reportados. Se vacunó un total de 80 317 embarazadas, de las cuales 615 reportaron eventos adversos, lo que representa 0,8 por ciento del total de gestantes vacunadas. En los niños la fiebre fue el síntoma que más notificaciones produjo (193), seguido de reacciones locales en el sitio de inyección (23), vómitos (20) artralgias (17), cefalea (11), decaimiento (10) y convulsiones relacionadas con fiebre (6). Se investigaron 8 eventos como severos. Conclusiones: con la aplicación de la vacuna estaban relacionados 3 eventos, otros 3 no relacionados con la aplicación de la vacuna y en 2 se decidió que eran no concluyentes (2 abortos espontáneos). No se reportaron fallecidos. Se demostró la capacidad del sistema de salud cubano para la aplicación de la vacuna con una vigilancia activa en un corto período de tiempo. En los datos derivados de la vigilancia de eventos supuestamente atribuidos a la vacunación o inmunización, no se reportó ningún evento inusual, por lo que no se sugieren problemas de seguridad relacionados con la vacuna Pandemrix.

Introduction: in April 2009, a new virus was identified in Mexico and North America as the cause of a respiratory disease. The virus quickly spread over other countries. On June 11, 2009 the World Health Organization (WHO) reported cases in 74 countries and territories located in 2 of its regions. The high sustained transmission of this virus worldwide led to establish the phase 6 or the pandemic phase, indicating that the situation had to do with spreading rather than increased severity. Objectives: to report on already known or new events after the administration of vaccine A(H1N1) called Pandemrix, to identify the most frequent events occurred in pregnant women and to research into the associated severe events. Methods: a prospective descriptive study was designed to characterize the adverse effects of Pandemrix reported across the country from April 1st to June 30th, 2010. A total of 1,123,526 people were vaccinated in which 100 percent of pregnant women were included. Results: active surveillance nationwide reported 5 763 signs and symptoms detected in 3 401 people (615 reports from pregnant women). The overall rate of reports was 302.7 x 100 000 doses administered. Adverse events such as fever, headache, pain, swelling and redness at the injection site, malaise, arthralgia, allergic reactions, nausea and vomiting were reported as common symptoms. These 10 symptoms and signs accounted for 79.1 percent of all the reported events. A total number of 80 317 pregnant women were vaccinated of whom 615 reported adverse effects, accounting for 0.8 percent of the vaccinated pregnant women. Fever was the most notified symptom in children (193) followed by local reactions at the injection site (23), vomiting (20), arthralgia (17), headache (11), malaise (10) and high fever-related seizures (6). Eight events were analyzed as severe. Conclusions: the administration of the vaccine was related to 3 events, unrelated to other 3 events and 2 were classified as inconclusive (3 miscarriages). No deaths were reported. The capacity of the Cuban Health System for the administration of this vaccine with active surveillance in a short period of time was proved. Data from monitoring of events that were supposedly attributable to vaccination or immunization did not notify any unusual event. Therefore, no safety problem is associated to the Pandemrix vaccine.
