Scientists seek a better, longer-lasting and more effective flu vaccine
....change is on the horizon.
Some of the new approaches already are coming to market.
Some researchers are focusing on the as-yet-unattainable ideal: a vaccine that would protect against all forms of the virus, with just one immunization every 10 years or so.
In November, the Food and Drug Administration approved Flucelvax, manufactured by Novartis, the first U.S.-licensed flu vaccine that uses cell culture technology. The virus is grown in dog kidney cells, instead of eggs. The cells can be frozen, ready to go quickly into vaccine production if a new virus is discovered. As Schaffner put it: "You don't have to wait for the roosters and hens to do their thing."
Two vaccines will be available next season that protect against four strains of the virus, instead of the standard three: a nasal spray by FluMist and an injectable vaccine by GlaxoSmithKline.
In January, the FDA approved Flublok, by Protein Sciences. It is made in insect cells using a protein from the virus -- hemagglutinin, instead of a live virus.
