Vaccination in pregnancy. Consensus document of the CAV-AEP and the SEGO.

During pregnancy, physiological changes in the immune response make pregnant women more susceptible to serious infection, increasing the risk for the mother as well as the foetus, newborn and infant. All women should be correctly and fully vaccinated as they enter their reproductive years, especially against diseases such as tetanus, hepatitis B, measles, rubella and varicella. In addition to the recommended vaccines, in risk situations, inactivated vaccines could be administered to women who were not correctly vaccinated before, while attenuated vaccines are contraindicated. Despite the fact that vaccination during pregnancy is a very important preventive measure and the existing recommendations from public health authorities, scientific societies and health professionals, the vaccination coverage could clearly be improved, especially against influenza and SARS-CoV-2, so any health professional involved in the care of pregnant women should proactively recommend these vaccines. The Spanish Association of Pediatrics (AEP), through its Advisory Committee on Vaccines, and the Spanish Society of Gynaecology and Obstetrics (SEGO) recommend vaccination against the following diseases during pregnancy: against influenza and COVID-19, in any trimester of pregnancy and during the postpartum period (up to 6 months post birth) in women not vaccinated during pregnancy; against pertussis, with the Tdap vaccine, between weeks 27 and 36 of gestation (in the CAV-AEP recommendations, preferably between weeks 27 and 28); and against RSV, with RSVPreF, between weeks 24 and 36 of gestation, preferably between weeks 32 and 36.

Vacunación en el embarazo. Documento de consenso del CAV-AEP y la SEGO / Vaccination in pregnancy. Consensus document of the CAV-AEP and the SEGO

Durante el embarazo, los cambios fisiológicos en la respuesta inmunitaria favorecen que las gestantes sean más susceptibles a infecciones graves, tanto para ellas como para el feto, el recién nacido y el lactante. Todas las mujeres deberían entrar en el período reproductivo con su calendario vacunal correctamente cumplimentado, sobre todo en lo que respecta a enfermedades como tétanos, hepatitisB, sarampión, rubeola y varicela. Además de las vacunas recomendadas, en situaciones de riesgo las vacunas inactivadas podrían ser administradas en aquellas mujeres que no estuvieran correctamente inmunizadas con anterioridad, mientras que las atenuadas están contraindicadas.A pesar de que la vacunación durante el embarazo es una medida preventiva muy importante, y de las recomendaciones de autoridades sanitarias, sociedades científicas y profesionales sanitarios, las coberturas vacunales son claramente mejorables, especialmente en lo que respecta a gripe y COVID-19, por lo que todo profesional sanitario que atienda a la embarazada debe ser proactivo en aconsejarlas.La Asociación Española de Pediatría (AEP), a través de su Comité Asesor de Vacunas (CAV), y la Sociedad Española de Ginecología y Obstetricia (SEGO) recomiendan las siguientes vacunaciones durante la gestación: frente a gripe y COVID-19, en cualquier trimestre del embarazo, y durante el puerperio (hasta los 6meses) en aquellas que no hubieran sido vacunadas durante la gestación; frente a tosferina con Tdpa, entre las 27 y 36 semanas de gestación (el CAV-AEP da preferencia entre las 27 y 28 semanas); y frente al VRS con RSVPreF, entre las 24 y 36 semanas de gestación, de preferencia entre las 32 y 36 semanas.

Calendario de inmunizaciones de la Asociación Española de Pediatría: recomendaciones 2024 / Immunisation schedule of the Spanish Association of Pediatrics: 2024 recommendations

El Calendario de Inmunizaciones de la AEP para 2024, con sus recomendaciones de inmunización para embarazadas, niños y adolescentes residentes en España, hace el número 25 desde el primero presentado en 1995, siendo anual desde 2003, como calendario de vacunaciones, y desde 2023 como calendario de inmunizaciones por la inclusión de un anticuerpo monoclonal para la prevención de la enfermedad por VRS. Como novedades de este año, se encuentran las siguientes: • Tabla de inmunizaciones sistemáticas para personas sanas y otra para pertenecientes a grupos de riesgo. • Aunque ya anteriormente se hacían recomendaciones de vacunación en embarazadas, se han añadido a la tabla y se ha creado un apartado específico. • Se recomienda la vacunación frente al neumococo con una de las nuevas vacunas conjugadas de valencia ampliada, en sustitución de VNC13. • Se recomienda la sustitución de la vacuna frente al meningococo C a los 4 meses de edad por la vacuna MenACWY, quedando la pauta recomendada como 1+1+1 (4 meses, 12 meses y 12 años, manteniendo el rescate en adolescentes hasta los 18 años). • Se recomienda la vacuna intranasal frente a gripe como la preferente en mayores de 2 años. • Siguiendo las propuestas de OMS, ECDC y CISNS, la vacunación frente al SARS-CoV-2 pasa a ser recomendada solo para personas mayores de 6 meses con factores de riesgo, con preparados que contengan el linaje XBB.1. Las recomendaciones de vacunación contra la covid en pediatría se actualizarán periódicamente en la web del CAV-AEP.Se mantienen el resto de las recomendaciones del calendario anterior.(AU)

The AEP Immunization Calendar for 2024, with its immunization recommendations for pregnant women, children and adolescents residing in Spain, marks the 25th edition since the first one was introduced in 1995, being annual since 2003, as a vaccination calendar, and since 2023 as immunization schedule due to the inclusion of a monoclonal antibody for the prevention of RSV disease. Novelties for this year include the following: • Tables of systematic immunizations for healthy people and those belonging to risk groups. • Although vaccination recommendations were previously made for pregnant women, they have been now included in the table and a specific section has been created. • Vaccination against pneumococcus is recommended with one of the new expanded valence conjugate vaccines, replacing PCV13. • It is recommended to replace the meningococcus C vaccine at 4 months of age with the MenACWY vaccine, thus leaving the recommended schedule as 1+1+1 (4 months, 12 months and 12 years, with a catch-up for adolescents up to 18 years). • The intranasal flu vaccine is recommended as the preferred vaccine for people over 2 years of age. • Following the proposals of the WHO, ECDC and CISNS, vaccination against SARS-CoV-2 is now recommended only for people over 6 months of age with risk factors, using vaccines containing the XBB.1 lineage. Vaccination recommendations against covid in pediatrics will be updated periodically on the CAV-AEP website.The rest of the recommendations from the previous calendar remain unchanged.(AU)

Efficacy and effectiveness of influenza vaccination in healthy children. A review of current evidence / Eficacia y efectividad de la vacunación frente a la gripe en niños sanos. Una revisión de la evidencia actual

Influenza is common in healthy children and adolescents and is associated with a high rate of hospitalization in this group, especially for those <5 years. Although the WHO has recommended vaccination in children under 5 years of age since 2012, it is really implemented in few countries today. The aim of this paper was to review the available evidence on the efficacy/effectiveness of influenza vaccination in healthy children <18 years of age through a non-systematic search of studies conducted between 2010 and 2020. Despite the high variability in results due to differences in design, vaccine type and season included in the 41 selected studies, statistically significant studies show efficacy values for the influenza vaccine of between 25.6% and 74.2%, and effectiveness from 26% to 78.8%. Although a systematic review would be necessary to corroborate the evidence, this review suggests that paediatric vaccination is generally an effective measure for preventing influenza in healthy children in line with international organisms’ recommendations.(AU)

La gripe tiene una elevada incidencia en niños y adolescentes sanos, y se asocia a una alta tasa de hospitalización, especialmente en los < 5 años. Desde 2012, la Organización Mundial de la Salud recomienda la vacunación en < 5 años, pero pocos países aplican hoy esta recomendación. El objetivo de este documento es revisar la evidencia disponible sobre la eficacia/efectividad de la vacunación antigripal en niños sanos < 18 años mediante una búsqueda no sistemática de estudios entre 2010-2020. A pesar de la gran variabilidad en los resultados debido a las diferencias de diseño, tipo de vacuna y temporada incluidos en los 41 estudios seleccionados, aquellos con significación estadística muestran valores de eficacia para la vacuna antigripal del 25,6% y al 74,2%, y de efectividad del 26% al 78,8%. Aunque sería necesaria una revisión sistemática para corroborar la evidencia, esta revisión sugiere que la vacunación pediátrica es globalmente una medida eficaz/efectiva para prevenir la gripe en niños sanos, en línea con las recomendaciones de organismos internacionales.(AU)

Immunisation schedule of the Spanish Association of Paediatrics: 2023 Recommendations.

As it does every year, the CAV-AEP publishes the update of its recommendations for the use of vaccines in children, adolescents and pregnant women residing in Spain. The 2 + 1 schedule is maintained in infants (at 2, 4 and 11 months), including preterm infants, with the hexavalent vaccine (DTaP-IPV-Hib-HB) and the pneumococcal 13-valent conjugate vaccine. A booster dose with DTaP-IPV is needed at 6 years for those who received the 2 + 1 series with hexavalent vaccine as infants, in addition to 1 dose of dTap in adolescence. Routine vaccination of pregnant women with a dose of dTap is recommended in each pregnancy, preferably between weeks 27 and 32 of gestation, although can be given from 20 weeks if there is risk of preterm delivery. All infants should receive the rotavirus vaccine (2-3 doses) and the 4CMenB vaccine (2 + 1 series). All children aged 6-59 months should be vaccinated against influenza each year. The MenACWY vaccine should be given routinely at 12 months of age and in adolescence between ages 12 and 18 years. The recommendations for the MMR vaccine (12 months and 3-4 years) and varicella vaccine (15 months and 3-4 years) also remain unchanged, using the MMRV vaccine for the second dose. Recommendations for the use of SARS-CoV-2 vaccines in the paediatric age group will be updated periodically on the CAV-AEP website. The HPV vaccine is indicated in all adolescents, regardless of sex, at age 12 years. Novelties include the recommendation of routine administration of nirsevimab to neonates and infants aged less than 6 months for passive immunization against RSV, and the recommendations regarding the hexavalent vaccine are consolidated in a single section.

Effectiveness of cell culture-based influenza vaccines compared with egg-based vaccines: What does the literature say? / Efectividad de la vacuna antigripal generada en cultivo celular frente a la producida en huevo: ¿Qué dice la literatura actual?

Introduction. Influenza vaccination is an effective wayof reducing the burden of seasonal influenza. Chicken eggembryos are the most common source of influenza vaccines,but cell culture production has emerged as an alternative thatcould be advantageous. This article reviews the available literature on the efficacy/effectiveness of cell culture-based influenza vaccines compared with egg-based vaccines.Methods. We conducted a review of the actual literatureand analyzed those studies comparing the effectiveness of cellculture-based and egg-based vaccines in the last ten years.Results. Eight studies were analyzed; 1 was a clinical trialand 7 were retrospective cohort studies. The clinical trial foundno significant differences in the efficacy of both vaccines withrespect to placebo. The results of the observational studieswere inconsistent and relative effectiveness varied amongstudies, even though most were performed during the sameseason, and in some cases, in the same region and using thesame data records. Furthermore, in most studies, the comparisons between vaccines were not statistically significant.Conclusions. There is insufficient evidence that cell culture-based vaccines are superior to egg-based vaccines interms of efficacy/effectiveness. (AU)

Introducción. La vacunación frente a la gripe es el método más efectivo para reducir el impacto de la gripe estacional.Los embriones de huevo de gallina son el método más comúnde fabricación de vacunas antigripales, pero la propagación encultivos celulares ha emergido como una alternativa que podría ofrecer alguna ventaja. El objetivo de este artículo es hacer una revisión de la literatura disponible sobre la efectividadde vacuna antigripal generada en cultivos celulares frente a lavacuna producida en huevo.Métodos. Se realizó una búsqueda bibliográfica de losestudios comparativos entre la vacuna propagada en cultivoscelulares y la producida en huevo con respecto a su efectividadpublicados en los últimos diez años.Resultados. De los siete estudios analizados, uno fue unensayo clínico y seis fueron estudios de cohortes retrospectivos. Los resultados del ensayo clínico mostraron que no existían diferencias significativas en cuanto a la eficacia de ambasvacunas. Con respecto a los estudios observacionales, los resultados fueron poco consistentes, con efectividades relativas quefueron muy diferentes entre estudios a pesar de que la mayoría se realizaron durante la misma temporada, y en algunosestudios, en la misma región y utilizando el mismo registro dedatos. Además, en la mayoría de los estudios no hubo significación estadística.Conclusiones. No existen evidencias suficientes de que lavacuna producida en cultivo celular sea superior a la generadaen huevo con respecto a su efectividad. (AU)

Epidemiology, prevention and control of pertussis in Spain: New vaccination strategies for lifelong protection.

Pertussis is a highly contagious, vaccine-preventable respiratory tract infection, with high morbidity and mortality and a particularly severe effect on newborns and infants under 2 months. The first pertussis vaccines were introduced in the 1940s. Since 1980, however, the incidence of cases has risen despite the extensive vaccination programmes and antibiotic adjuvant treatments available. Transition from the use of whole-cell vaccines to acellular vaccines and the antigenic modifications of Bordetella pertussis have contributed, among other factors, to a reduction in vaccine-acquired immunity and reemergence of the disease. Today, there are still unmet needs not covered by conventional prevention measures and existing antibiotic treatments. This review aims to update the available data, and to discuss which vaccine strategies might contribute to better disease control and prevention.

Epidemiology, prevention and control of pertussis in Spain: New vaccination strategies for lifelong protection / Epidemiología, prevención y control de la tosferina en España: nuevas estrategias de vacunación para la protección a lo largo de la vida

La tosferina es una infección respiratoria inmunoprevenible altamente contagiosa, con alta morbilidad y mortalidad, y que afecta con especial gravedad a recién nacidos y lactantes menores de 2 meses. Las primeras vacunas comenzaron a emplearse en la década de los 40. Sin embargo, desde 1980 la incidencia de casos ha aumentado a pesar de los amplios programas de vacunación y tratamientos antibióticos adyuvantes disponibles. El cambio del uso de vacunas celulares a vacunas acelulares, y las modificaciones antigénicas de B. pertussis han podido contribuir entre otros factores a la disminución de la inmunidad adquirida tras la vacunación y a la reemergencia de la enfermedad. En la actualidad, todavía existen necesidades no cubiertas por las medidas convencionales de prevención y los tratamientos antibióticos existentes. Esta revisión pretende actualizar los datos disponibles y plantear qué estrategias vacunales pueden contribuir a un mejor control y prevención global de la enfermedad.

Impacto de la vacunación frente a tosferina en España: informe de la sesión científica extraordinaria celebrada en la Real Academia Nacional de Medicina (28/09/2020) / Impact of whooping cough vaccination in Spain: report from the extraordinary scientific meeting held at the Royal National Academy of Medicine. September 28th, 2020

La Real Academia Nacional de Medicina celebró en septiembre 2020 la sesión científica extraordinaria "Impacto de la vacunación frente a tosferina en España". La incidencia de tosferina ha aumentado a nivel mundial desde 2010. El alarmante incremento de hospitalizaciones relacionadas con la tosferina especialmente en niños menores de 1 año promovió la toma de decisiones orientadas a mejorar su protección. En 2014 la Organización Mundial de la Salud recomendó la vacunación durante el embarazo para proteger a los recién nacidos hasta que pudieran completar la primovacunación. En España, esta medida se implantó en 2016 y desde entonces se ha registrado una disminución significativa de hospitalizaciones y de muertes en niños menores de 1 año. La implantación de estrategias apropiadas de inmunización, el reconocimiento de la importancia de la vacunación a lo largo de toda la vida y la investigación en vacunas de mayor eficacia son claves para un control global de la tosferina

The Royal National Academy of Medicine of Spain held a special session on "The impact of vaccination against pertussis in Spain" in September 2020. The incidence of pertussis worldwide has increased since 2010. The alarming increase in the rate of hospitalization among children younger than 1 year of age prompted decisions aimed at improving their protection. In 2014, the World Health Organization recommended vaccination during pregnancy to protect newborns until they could complete the primary series of vaccinations. In Spain, this measure was implemented in 2016 and, since then, a significant drop in hospitalization and deaths among children younger than 1 year has been recorded. The implementation of appropriate immunization strategies, the recognition of the importance of vaccination throughout life, and research into new vaccines with higher efficacy are key to achieving global control of pertussis

Likewise, it is recommended in those over 6 weeks of age with risk factors or who travel to countries with a high incidence of these serogroups. Two-dose schedules for MMR (12 months and 3-4 years) and varicella (15 months and 3-4 years) will be used. The second dose could be applied as a tetraviral vaccine. Universal systematic vaccination against HPV is recommended, both for girls and boys, preferably at 12 years, and greater effort should be made to improve coverage. The 9 genotype extends coverage for both genders.

Calendario de vacunaciones de la Asociación Española de Pediatría: recomendaciones 2020 / Immunisation schedule of the Spanish Association of Paediatrics: 2020 recommendations

El CAV-AEP publica anualmente el calendario de vacunaciones que estima idóneo para los niños residentes en España, teniendo en cuenta la evidencia científica disponible. Se mantiene el esquema 2 + 1 (2, 4 y 11 meses) con vacunas hexavalentes (DTPa-VPI-Hib-HB) y con antineumocócica conjugada 13-valente. Se aconseja un refuerzo a los 6 años, preferentemente con DTPa (si está disponible), junto a una dosis de polio para aquellos que recibieron esquemas 2 + 1, así como vacunación con Tdpa en adolescentes y en cada embarazo, preferentemente entre las 27 y las 32 semanas. La vacuna del rotavirus debería ser sistemática para todos los lactantes. Se sigue proponiendo la incorporación en el calendario de la vacuna antimeningocócica B, con esquema 2 + 1 en lactantes. Además de la inclusión de la vacuna antimeningocócica conjugada tetravalente (MenACWY) a los 12 años con rescate hasta los 18 años, inclusive, el CAV recomienda que esta vacuna sea introducida también a los 12 meses de edad, sustituyendo a MenC. Igualmente, se recomienda en los mayores de 6 semanas de edad con factores de riesgo o que viajen a países de elevada incidencia de estos serogrupos. Se emplearán esquemas de 2 dosis para triple vírica (12 meses y 3-4 años) y varicela (15 meses y 3-4 años). La segunda dosis se podría aplicar como vacuna tetravírica. Se recomienda la vacunación sistemática universal frente al VPH, tanto a chicas como a chicos, preferentemente a los 12 años, debiendo realizar un mayor esfuerzo para mejorar las coberturas. La de 9 genotipos amplía la cobertura para ambos sexos

The CAV-AEP annually publishes the immunisation schedule considered optimal for all children resident in Spain, taking into account the available evidence. The 2 + 1 schedule is recommended (2, 4, and 11 months) with hexavalent vaccines (DTPa-VPI-Hib-HB) and with 13-valent pneumococcal conjugate. A 6-year booster is recommended, preferably with DTPa (if available), with a dose of polio for those who received 2 + 1 schemes, as well as vaccination with Tdpa in adolescents and in each pregnancy, preferably between 27 and 32 weeks. Rotavirus vaccine should be systematic for all infants. Meningococcal B vaccine, with a 2+1 schedule, should be included in routine calendar.

Recomendaciones para la vacunación frente al ROTAvirus de los recién nacidos PREMaturos (ROTAPREM) / Recommendations for vaccination against ROTAvirus in PREMature newborns (ROTAPREM)

El rotavirus (RV) es la causa principal de diarrea infantil grave en todo el mundo e infecta prácticamente a todos los niños en los primeros 5 años de vida, sobre todo en los primeros 2años. Existen dos vacunas atenuadas de administración oral frente al RV disponibles en nuestro medio que han demostrado ser seguras y eficaces frente a la enfermedad. El objetivo principal de estas vacunas ha sido reproducir la historia natural de la infección y proteger frente a la enfermedad grave en los primeros meses de vida. Los recién nacidos prematuros son especialmente vulnerables a la enfermedad por RV, no solo por tener más riesgo de adquirir la infección, sino también por sus complicaciones. La vacunación frente al RV en niños prematuros ha mostrado resultados de eficacia y seguridad similares a los comunicados en niños a término, y los datos existentes sugieren un riesgo bajo de diseminación e infección nosocomial cuando la vacunación se realiza durante la hospitalización. Dado que un porcentaje estimable de recién nacidos prematuros permanecen ingresados en las unidades neonatales más allá de las 12semanas de vida, se considera que estos, siempre que su condición clínica lo permita, deben recibir la vacunación frente al RV sin retrasos, incluso durante la hospitalización si así fuese necesario

Rotavirus (RV) is the leading cause of severe acute gastroenteritis in infants worldwide. Most children are infected by RV by the age of 5 years, and especially in the first 2 years. Two oral attenuated vaccines against RV are licensed in industrialised countries, which have proven to be safe and effective against the disease. The main objective of these vaccines has been to reproduce the natural history of infection and protect against severe disease in the first months of life. Preterm infants are at higher risk of severe RV infection compared to full-term infants and infants with normal birth weight. Data collected on RV vaccination in preterm infants demonstrated that RV vaccines are effective and safe, compared with full-term infants, with a marginal risk of horizontal viral transmission and dissemination when vaccination is performed during hospitalisation. Preterm infants frequently require admission to hospital after the beginning of the 12 th week of life, which suggests that they should receive RV vaccines during admission according to the official immunisation schedule
