Universal Flu Vaccine on the Way
New studies are underway to develop a universal flu vaccine designed to protect against all potential varieties of influenza virus, including swine flu and bird flu. This research is especially important as health workers try to figure out how to get the new avian flu vaccine to everyone who may be exposed to the virus in the future.
Researchers plan to incorporate elements that are identical in all human virus strains, which should make the vaccine effective against all future flu variants. This would avoid the problem of having to create new flu vaccines every year, as the viruses mutate.
