Una vacuna intranasal contra la gripe aviar previene la infección en ratones
Un equipo de científicos de la Universidad de Washington en St. Louis desarrolló una vacuna intranasal contra la gripe aviar H5N1 que genera una fuerte respuesta inmunitaria y previene la infección en modelos animales, incluso en individuos previamente vacunados o infectados por gripe
TL;DR
- A new intranasal H5N1 avian flu vaccine has been developed by scientists at Washington University in St. Louis.
- The vaccine generated a strong immune response and provided near-complete protection against infection in hamsters and mice.
- It remains effective even in animals previously vaccinated or infected with other flu strains.
- The intranasal administration targets the upper respiratory tract, potentially disrupting infection and transmission.
- Current seasonal flu vaccines offered little protection against H5N1 in the animal models.
