Mallory et al [ 29 ] (2018) en sus estudios de seguridad y eficacia de Q/LAIV en niños japoneses, observaron que fue generalmente bien tolerada y los eventos adversos fue similar a la observada en estudios realizados fuera de Japón. Pepin et al [ 30 ] (2018), confirmaron la eficacia clínica de dos dosis completas de IIV4 (15 µg HAI/cepa) para prevenir la gripe en niños de 6 a 35 meses.…”
