The primary endpoint comprises a composite endpoint of either an increase in anti-RBD antibody titre to ≥500 IU/mL at day 14 post 4th dose booster vaccine in those with anti-RBD antibody titre of ≤500 IU/mL immediately before 4th dose booster vaccination or a 2-fold increase in anti-RBD antibody titre at day 14 following 4th dose vaccination in those with anti-RBD titre of ≥500 IU/mL immediately before 4th dose booster vaccination, as measured by quantitative immunoassay targeting the anti-RBD antibody. La variable principal del estudio es una variable compuesta de un aumento en el título de anticuerpos RBD a ≥500 IU/mL en el día 14 tras haber recibido la 4ª dosis de la vacuna en aquellos con un título de anticuerpos RBD de ≤500 IU/mL inmediatamente antes de la 4ª dosis de la vacuna, o un aumento de 2 veces en el título de anticuerpos RBD en el día 14 después de recibir la 4ª dosis de la vacuna en aquellos con título RBD de ≥500 IU/mL inmediatamente antes de recibir la 4ª dosis de la vacuna, medido por inmunoensayo dirigido al anticuerpo RBD |
