Vaccinations are one of the main public health tools for the control of vaccine-preventable diseases. If a child is identified as having had an allergic reaction to a vaccine, subsequent immunisations will probably be suspended - with the risks such a decision implies. The incidence of severe allergic reactions is very low, ranging between 0.5 and 1 cases/100,000 doses. Rather than the vaccine antigens as such, the causes of allergic reactions to vaccines are often residual protein components of the manufacturing process such as gelatine or egg, and less commonly yeasts or latex. Most vaccine reactions are mild and circumscribed to the injection site; although in some cases severe anaphylactic reactions can be observed. If an immediate-type allergic reaction is suspected at vaccination, or if a child with allergy to some of the vaccine components is scheduled for vaccination, a correct diagnosis of the possible allergic process must be made. The usual vaccine components must be known in order to determine whether vaccination can be safely performed.

This study assesses whether the use of digital tablets in the context of Bring Your Own Device (BYOD) produces an alteration in the academic performance of high school music students. The grades of high school students were analysed and compared for two groups: experimental and control. The experimental group carried out the experiment using digital tablets, while a traditional methodology was used by the control group. The conclusions showed similar results regarding academic performance for a specific unit of the music subject. Students who used their own digital devices obtained statistically similar results to students who followed a more conservative process (even slightly superior in some parameters). Furthermore, there were no significant differences regarding gender. The research concludes that digital tablets in the music classroom are not a barrier for the academic performance of students, but rather a tool that helps in the teaching-learning process.

The present work analyzes the use of the song as a didactic tool in the field of Primary Education, for which a study was carried out with a total of 128 general teachers of Primary Education (22.7% women) active in the Community. of Castilla y León in Spain, and without a specific musical training. The fundamental objective was to know the musical tools that they use in their classes (especially the song) according to the years of teaching experience. The main results show that music as a transversal tool is highly valued by generalist teachers in line with other research, although there are relevant differences in the use of the song according to the years of teaching experience, with veterans being the ones who use music the most. same. Finally, the causes that may have influenced the decrease in the use of songs as a didactic resource –traditionally considered highly useful and effective– are analyzed and some measures are proposed to enhance it. El presente trabajo analiza el uso de la canción como herramienta didáctica en el ámbito de la Educación Primaria, para ello se realizó un estudio con un total de 128 maestros y maestras generalistas de Educación Primaria (22,7% mujeres) en activo de la Comunidad de Castilla y León en España, y sin una formación musical específica. El objetivo fundamental fue conocer las herramientas musicales que utilizan en sus clases (especialmente la canción) según los años de experiencia docente. Los resultados principales vislumbran que la música como herramienta transversal es altamente valorada por los maestros generalistas en consonancia con otras investigaciones, aunque existen diferencias relevantes en el uso de la canción según los años de experiencia docente, siendo los veteranos los que más uso hacen de la misma. Por último, se analizan las causas que han podido influir en la minoración del uso de la canción como recurso didáctico –tradicionalmente considerado de gran utilidad y efectividad– y se proponen algunas medidas para potenciarlo.
