RESUMO
Ante un cambio radical en el comportamiento en un varón de 17 años, a las 12 horas de administrar, en el mismo día, las vacunas contra el Meningococo C, Hepatitis B, Triple Vírica y Varicela, y la detección de un cuadro maníaco a la semana, se sospechó que se tratase de un cuadro de encefalitis post-vacunal. A pesar de la ausencia de hallazgos patológicos en las exploraciones complementarias realizadas, y aunque en la literatura científica no se haya demostrado una asociación temporal a día de hoy, no podemos aceptar ni descartar con certeza la sospecha diagnóstica dado que no contamos con la serología infecciosa o un estudio de anticuerpos en líquido cefalorraquídeo. Los efectos secundarios graves tras vacunaciones no han quedado claramente demostrados, lo que sí está ampliamente demostrado es que la inmunidad adquirida es uno de los mayores logros de la medicina que ha ayudado a erradicar enfermedades potencialmente mortales
A radical behavioral change was observed in a 17-year-old male 12 hours after having received vaccines for Meningococcus C, Hepatitis B, Triple Viral and Varicella on the same day. Moreover a manic episode was detected one week later. It was suspected that this was a case of post-vaccinal encephalitis. In spite of the absence of pathological findings in the complementary explorations carried out and although a temporal association has not been demonstrated to date in the scientific literature, we can not be certain of this diagnostic suspicion since we do not have the infectious serology or a study of antibodies in central spinal fluid. Serious side effects after vaccinations have never been clearly demonstrated, while it has been widely demonstrated that the acquired immunity from these vaccines is one of the greatest achievements of medicine, and this has helped to eradicate life-threatening diseases
