Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The flu is a constant threat that can sometimes cause severe forms of disease. The highest incidence rates by age group occur in children under 15 years of age, especially in those under 5 years, in whom the rate of hospitalization is also similar to the population aged 65 years and older. In addition, children are the main transmitters of the infection. In Spain, 5 influenza vaccines are authorized for the paediatric age group: three inactivated tetravalent vaccines harvested from fertilised eggs, one tetravalent inactivated vaccine obtained from cell cultures and one attenuated tetravalent vaccine for intranasal administration, which will become trivalent in the 2024−2025 season by excluding the B Yamagata lineage as recommended by the WHO. The CAV-AEP recommends systematic vaccination in children aged 6–59 months, children and adolescents belonging to risk groups, people who can transmit the flu to groups at risk of complicated flu, and household contacts or close family of infants under 6 months. From 2 years of age, the intranasal attenuated vaccine is preferred due to its greater acceptability and thus contribution to greater vaccination coverage. The CAV-AEP also considers that vaccination against influenza of healthy children and adolescents aged 5–18 years is advisable, as it provides individual protection and promotes protection at the family and community levels. It is especially important to vaccinate all health care professionals against influenza as well as pregnant women at any time during pregnancy. La gripe es una amenaza constante, que en ocasiones puede producir cuadros clínicos graves. Las mayores tasas de incidencia por grupos de edad ocurren en los menores de 15 años, especialmente en los menores de 5 años, en los que además las tasas de hospitalización son similares a las de las personas de 65 años en adelante. Además, los niños son los principales vectores de transmisión de la enfermedad. En España, están autorizadas cinco vacunas antigripales en la edad pediátrica: tres inactivadas tetravalentes procedentes de cultivos en huevos embrionados, una inactivada tetravalente procedente de cultivos celulares, y una atenuada tetravalente de administración intranasal, que para la temporada 2024−2025 pasará a ser trivalente, al no incluir el linaje B Yamagata como recomienda la OMS. El CAV-AEP recomienda la vacunación sistemática en: niños de 6 a 59 meses, niños y adolescentes pertenecientes a grupos de riesgo, personas que puedan transmitir la gripe a los grupos que tienen riesgo de gripe complicada, y convivientes o entorno familiar de menores de 6 meses. A partir de los 2 años de edad, se recomienda preferentemente la vacuna atenuada intranasal por su mayor aceptabilidad y facilitar la mejora de las coberturas. El CAV-AEP considera también que la vacunación antigripal de niños y adolescentes de 5–18 años sanos es una medida recomendable, por cuanto le proporciona protección individual y favorece la protección familiar y comunitaria. Es especialmente importante la vacunación antigripal de todos los profesionales sanitarios y la vacunación de las gestantes en cualquier momento del embarazo.
