Experimental flu vaccine

Experimental vaccine protects against many flu viruses

A catchall flu shot is a step closer to reality. Researchers report May 22 in Nature that they have engineered a vaccine that immunizes mice and ferrets against decades’ worth of influenza viruses. They say it could protect people for several years — and from many different flu viruses — without having to be reformulated and delivered annually the way current flu vaccines are.

Researchers from the National Institutes of Health have engineered a nanoparticle vaccine that shields lab animals from several viruses that sickened people between 1934 and 2007. This vaccine won’t stop all flu viruses, but it may immunize against many versions of H1N1, a subtype of influenza A that causes many cases of seasonal flu.
