Immunisation schedule of the Spanish Association of Pediatrics: 2024 recommendations.

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: The rest of the recommendations from the previous calendar remain unchanged.

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.

Immunization schedule of the Pediatric Spanish Association: 2022 recommendations.

After reviewing the best available scientific information, CAV-AEP publishes their new recommendations to protect pregnant women, children and adolescents living in Spain through vaccination. The same recommendations as the previous year regarding hexavalent vaccines, pneumococcal conjugate vaccine of 13 serotypes, booster with tetanus, diphtheria, pertussis and inactivated poliomyelitis (Tdpa-IPV) at 6 years and with tetanus, diphtheria and pertussis (Tdpa) at 12-14 years and pregnant women from week 27 (from week 20 if there is a high risk of preterm delivery). Also with rotavirus, tetraantigenic meningococcal B (2+1), meningococcal quadrivalent (MenACWY), MMR, varicella and human papillomavirus (HPV) vaccines, for both genders. As novelties this year the CAV-AEP recommends: Influenza vaccination from 6 to 59 months of age whenever feasible and does not harm the vaccination program aimed at people at higher risk. According to official national recommendations, the CAV-AEP recommends the systematic use of COVID mRNA vaccines since 5 years old.

Calendario de vacunaciones de la Asociación Española de Pediatría: Recomendaciones 2022 / Immunisation schedule of the Pediatric Spanish Association: 2022 recommendations

Tras la revisión de la mejor información científica disponible, el CAV-AEP publica las nuevas recomendaciones para proteger con vacunas a las embarazadas, los niños y los adolescentes residentes en España. Se mantienen las mismas recomendaciones que el año anterior en cuanto a las vacunas hexavalentes y a la vacuna neumocócica conjugada de 13 serotipos, al refuerzo con tétanos, difteria, tosferina y poliomielitis inactivada (Tdpa-VPI) a los seis años y con tétanos, difteria y tosferina (Tdpa) a los 12-14 años y a las embarazadas a partir de la semana 27 (desde la semana 20 si hay alto riesgo de parto pretérmino). Lo mismo sucede con las vacunas del rotavirus, del meningococo B tetraantigénica (2 + 1), de la vacuna meningocócica tetravalente (MenACWY), de la triple vírica, de la varicela y de la vacuna del virus del papiloma humano (VPH), en ambos géneros.Como novedades este año el CAV-AEP recomienda: La vacunación antigripal de seis a 59 meses de edad siempre que sea factible y no perjudique al programa vacunal dirigido a las personas de mayor riesgo. En consonancia con las recomendaciones oficiales nacionales, el CAV-AEP recomienda el uso sistemático a partir de los 5 años de las vacunas para la COVID-19 de ARNm. (AU)

Conocimientos y retos sobre COVID-19 y población pediátrica / Knowledge and challenges on COVID-19 and the paediatric population

La pandemia del SARS-CoV-2 nos plantea muchas reflexiones y un futuro incierto. Pero, también ha sido una oportunidad para abrir nuevos retos en la investigación pediátrica. En Cataluña se constituyó un grupo de investigación multidisciplinario (COPEDI-CAT) formado por pediatras de hospital y de Atención Primaria y físicos de la unidad de Biología Computacional y Sistemas Complejos (BIOCOM-SC) de la Universidad Politécnica de Cataluña para dar respuesta a algunas de las incógnitas que nos generaba la enfermedad por SARS-CoV-2 en la edad pediátrica. En un primer estudio, al inicio de pandemia, demostramos que los niños y adolescentes no eran los motores de la propagación del virus: el 70% de los casos positivos se contagiaron de algún adulto conviviente y solamente el 7,7% fueron los casos índice dentro del núcleo familiar. En otro estudio realizado para conocer la transmisión del virus en los grupos burbuja de las escuelas, se observó que el 75% de los casos positivos no contagiaron a ningún compañero del grupo. También constatamos que la mayor parte de los niños y adolescentes eran asintomáticos o padecían la COVID-19 de forma leve y evolucionaban favorablemente. Las hospitalizaciones y las complicaciones están descritas, pero son muy poco frecuentes. En la quinta ola, la variante delta del SARS-CoV-2 ha afectado mucho más a los niños (20%) que en las anteriores olas. Gracias al esfuerzo y a la inversión realizada, la investigación ha dado sus frutos y ya disponemos de vacunas eficaces y seguras. Las vacunas nos han situado en un escenario mucho más optimista, pero con toda la información científica disponible y con la variante delta predominante, es inevitable plantearse si la vacunación en los menores de 12 años podría ofrecerles ventajas, a ellos y a la población general (AU)

The SARS-CoV-2 pandemic has given us many reflections and an uncertain future. But it has also been an opportunity to open to new challenges in paediatric research. In Catalonia, a multidisciplinary research group (COPEDI-CAT) formed by hospital and primary care paediatricians and physicists from the Computational Biology and Complex Systems Unit (BIOCOM-SC) of the Polytechnic University of Catalonia was set up to answer some of the unknowns about SARS-CoV-2 infection in the paediatric age group. In a first study, at the beginning of the pandemic, we demonstrated that children and adolescents were not the driving force behind the spread of the virus: 70% of the positive cases were transmitted by a cohabiting adult and only 7.7% were index cases within the family nucleus. In another study on the transmission of the virus in school bubble groups, we found that 75% of the positive cases did not infect any of their peers. We also found that most of the children and adolescents were asymptomatic or had mild COVID-19 and were progressing favourably. Hospitalisations and complications are described but are very rare. In the fifth wave, the SARS-CoV-2 delta variant has affected significantly more children (20%) than in previous waves. Thanks to the effort and investment made, research has borne fruit and we now have effective and safe vaccines. Vaccines have put us in a much more optimistic scenario, but with all the scientific information available and with the predominant delta variant, it is inevitable to ask... (AU)

Fonaments bàsics de les vacunes contra la covid-19 / Fundamentos básicos de las vacunas contra la covid-19 / Basics of covid-19 vaccines

A començaments de l’any 2020 s’estén arreu del món unapandèmia provocada pel SARS-CoV-2, un virus respiratoriemergent procedent de la Xina i causant de la malaltiaconeguda com a covid-19. D’aleshores ençà, l’obtenciód’una vacuna ha esdevingut una cursa contrarellotge arreudel món. Equips d’investigació d’universitats i farmacèuti-ques assagen vacunes basades en diferents tecnologies,algunes ja utilitzades històricament i altres de nova gene-ració. Actualment n’hi ha centenars en diferents fasesd’investigació. Això, juntament amb el gran impacte quegenera la malaltia a la societat, fa que estiguem sotmesosa una allau constant d’informació sobre les vacunes contrala covid-19. Aquest treball de revisió pretén aclarir algunsconceptes que ens permetin ser crítics amb la informaciórebuda i, al mateix temps, aclarir termes i generalitats so-bre els diferents tipus de vacunes, la seva regularització,producció i efectes secundaris.(AU)

A comienzos de 2020 se extiende por el mundo una pandemiaprovocada por el virus SARS-CoV-2, un virus respiratorio emer-gente procedente de China y causante de la enfermedad conocidacomo covid-19. A partir de entonces, la obtención de una vacunase ha convertido en una carrera contrarreloj alrededor del mundo.Equipos de investigación de universidades y farmacéuticas ensa-yan vacunas basadas en diferentes tecnologías, algunas ya utiliza-das históricamente y otras de nueva generación. Actualmente haycentenares en diferentes fases de investigación. Esto, junto con elgran impacto que genera la enfermedad en la sociedad, hace queestemos sometidos a un alud constante de información sobre lasvacunas contra la covid-19. Este trabajo de revisión pretende acla-rar algunos conceptos que nos permitan una lectura crítica de lainformación y aclarar simultáneamente términos y generalidadessobre los diferentes tipos de vacunas, su regularización, produc-ción y efectos secundarios.(AU)

Early in 2020, a pandemic caused by a new respiratory virus na-med SARS-CoV-2 -causing the COVID-19 disease- extended aroundthe world from China. From that moment on a global race for thevaccine commenced at universities and the pharmaceutical indus-try using different methods and technologies, including both tradi-tional and new generation strategies. Nowadays, hundreds of themare under different phases of development. This, along with thestrong social impact of the disease, floods social media with infor-mation about the progresses of the different working groups. Thispaper sheds light on concepts that allow one to scrutinize suchinformation critically and clarify terms and generalities about diffe-rent vaccines, their regularization, production and side effects.(AU)
