Este trabajo sugiere que la defensa en la nariz pesa tanto o más, lo que puede orientar futuras vacunas y tratamientos. Para una familia argentina con un bebé en invierno, esto abre la puerta a protecciones más eficaces. Todavía es un estudio observacional en un número acotado de niños, así que no cambia por sí solo la práctica médica.","quienFirma":"Preprint en medRxiv (institución principal no identificada en el resumen)","confianza":"preprint","consulta":null},"sello":{"hash":"fb706fb8bbea4b0edbb180cad42fe8d557aadb8f07d74de15b042ea0242e9620","sello":"7756eda925e5786fe8590461f7cb6563bd2d68ccdaad7672f9a16ec2d00d3220","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6587335,"aleatorio":"a73051692e7404084f9ff25789f872adba75b6b2ccf7d767ab32bc74031b260a","tiempo":"2026-10-26T21:44:30.000Z"},"nist":{"cadena":2,"pulso":2000861,"salida":"7270D97C2D57F9CB7EB7B095A08C5FEB9B89AB79EC9A8CA95295DF433D69A435C33F40AA23444ADF25BC5940158B01E8B7275199BCC1D89A41E5D4F68D952C8B","tiempo":"2026-10-26T21:44:00.000Z"},"noAntes":"2026-10-26T21:44:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 26 21:45:11 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Nasal Mucosal Immunity is Associated with Protection against RSV Illness in Infants","descripcion":"Background. Despite advances in respiratory syncytial virus (RSV) immunoprophylaxis, RSV remains a leading cause of severe respiratory illness in infants. Immunity at the site of infection is potentially important yet airway mucosal immunity against RSV infection remains poorly defined. Methods. We collected nasal and blood samples across three pediatric cohorts: 1) children presenting to the emergency department with respiratory symptoms; 2) infants and mothers presenting to an urban hospital system across the RSV season; 3) infants born to mothers vaccinated with maternal pre-Fusion (F) vaccine. We analyzed mucosal and serologic anti-RSV antibodies and assessed for factors impacting titer ","pubDate":"2026-10-26","url":"https://www.medrxiv.org/content/10.64898/2026.10.22.26366243v1?rss=1"},"indexado":"2026-10-26T21:44:45.754Z"}}
