Toxicidad a dosis repetida e inmunogenicidad en Cercopithecus aethiops, del candidato vacunal SOBERANA 01(FINLAY-FR-01) contra el coronavirus de tipo 2 causante del síndrome respiratorio agudo severo

Abstract

En el Instituto Finlay de Vacunas se desarrolló el candidato vacunal SOBERANA 01 (FINLAY-FR-01) contra el coronavirus de tipo 2 causante del síndrome respiratorio agudo severo. Este trabajo tuvo como objetivo evaluar la inmunogenicidad y posibles efectos toxicológicos del candidato vacunal SOBERANA 01 (FINLAY-FR-01 en Cercopithecus aethiops. Se utilizaron cinco primates no humanos (hembras), de 1-3 años de edad y 1-4 kg de peso corporal, distribuidos en dos grupos experimentales: Control (Solución Salina Fisiológica) y Tratado SOBERANA 01 (FINLAY-FR-01). El estudio se extendió por 84 días, en un esquema a dosis repetida de cuatro inmunizaciones los días 0, 28, 56 y 70. Se realizaron observaciones clínicas diarias, peso corporal, signos vitales (temperatura rectal, frecuencia respiratoria, y frecuencia cardíaca), exámenes electrocardiográficos, toma de la temperatura del sitio de inyección, musculometría e irritabilidad dérmica. Fueron realizados exámenes de hematología, bioquímica sanguínea, así como estudios inmunológicos. El ensayo concluyó con una supervivencia del 100%, no se manifestaron signos de toxicidad, no hubo variaciones hematológicas, ni de la bioquímica sanguínea asociadas a la sustancia de ensayo. Además, no se observaron efectos locales en el sitio de administración. Por último, el candidato vacunal resultó inmunogénico, ya que se indujeron títulos altos de IgG anti-RBD, así como de la inhibición de la unión de RBD a ACE2.
