Resumen

El candidato vacunal E2-CD154 es una vacuna de subunidad cuya seguridad y capacidad protectora en crías frente a la peste porcina clásica ha sido demostrada en estudios previos. Esos hallazgos se confirman en el presente estudio de fase III realizado en dos unidades de producción porcina en la provincia de Pinar del Rio con un número mayor de animales. Todos los animales en ambas granjas recibieron dos dosis de E2-CD154 los días 0 y 21. El estudio se extendió por 60 semanas, la vacuna fue bien tolerada en las crías vacunadas entre los 15 y 28 días de edad, no se documentaron efectos adversos locales o sistémicos. Las cerdas gestantes inmunizadas fueron capaces de trasmitir altos títulos de anticuerpos a sus crías (Unidad A, media geométrica = 1:1295, valor mínimo 1:100 y Unidad B, media geométrica = 1:474, valor mínimo 1:150), muy por encima del umbral de protección (1:50). Estos elevados títulos de anticuerpos neutralizantes derivados de la madre no interfirieron con la inmunogenicidad del candidato vacunal en estudio. Todas las crías vacunadas estudiadas al azar (más del 10% de las 2804) desarrollaron títulos de anticuerpos neutralizantes mayores de 1:400 en los cuatro muestreos realizados (nueve, 21, 41, y 44 semanas) en ambas granjas. Los resultados de este estudio confirman la seguridad, inmunogenicidad y robustez del candidato vacunal en esta sensible categoría en condiciones de campo.
