Un modelo como este permite probar esquemas de vacunación en la computadora antes de hacerlos en personas. Para alguien de acá, significa que parte del camino para mejorar vacunas se recorre con cálculos además de con pinchazos. El modelo se ajustó a un solo ensayo, así que su capacidad de predecir otros casos todavía debe comprobarse.","quienFirma":"bioRxiv (preprint; institución principal no identificada en el extracto)","confianza":"preprint","consulta":null},"sello":{"hash":"5481e806003bdb078b3d0b6f5da88c93045f049aa30189609215ef1273334f53","sello":"c88c3310c027ae25a5a93974948b37af75e2203b402e561e69ea9302b5101cbc","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6570990,"aleatorio":"197cfefbaae84a11019800f736fb3d999fc9deaffc98cec0c35453a67bb3b551","tiempo":"2026-10-21T05:32:00.000Z"},"nist":{"cadena":2,"pulso":1992700,"salida":"779B9C05152B4CBD1C0DC8A789A98414BB1FB7FC9BCD4C986DB35B0B6DFFACF69BCA3C8A248326F1AFCD58751A3730795B71A1BBC058A265C3BB6F3B3B74127C","tiempo":"2026-10-21T05:31:00.000Z"},"noAntes":"2026-10-21T05:32:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 21 05:32:48 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"A Multiclass Mechanistic Model of Vaccine-Induced Humoral Response","descripcion":"Vaccine-induced humoral immunity emerges from complex interactions among competing B-cell populations and antibody production in response to antigen exposure, yet the mechanisms governing these interactions remain only partially understood. We developed a mechanistic mathematical model that integrates vaccine regimen features, immunogen kinetics, multiclass B-cell dynamics, and germinal center processes. The model was calibrated to data from the G001 HIV vaccine trial evaluating eOD-GT8, a germline-targeting immunogen designed to activate VRC01-class precursor B cells capable of developing into broadly neutralizing antibody-producing cells. The model reproduced key features of the observed B","pubDate":"2026-10-20","url":"https://www.biorxiv.org/content/10.64898/2026.10.14.759230v1?rss=1"},"indexado":"2026-10-21T05:32:19.019Z"}}
