Penn Medicine Develops Potent mRNA Vaccine Against Lethal H5N1 Virus

Experimental mRNA vaccine proves highly effective against H5N1 in animal studies, offering hope for rapid pandemic response.

Researchers from the Perelman School of Medicine at the University of Pennsylvania have developed an experimental mRNA vaccine against avian influenza virus H5N1. The vaccine is highly effective in preventing severe illness and death in preclinical models and could help manage the current H5N1 outbreaks in birds and cattle in the United States and prevent its transmission to humans.
