Crafting better flu shots comes down to dispensing with 1940s technology, according to CSL Ltd., which says its new method of vaccine production may offer better protection against the virus that killed almost 200 American children last season.
Flucelvax, an immunization produced by CSL’s Seqirus unit with cell-based technology, was 36.2 percent more effective in preventing flu-like illness last winter than conventional shots made using chicken eggs, the Melbourne-based company said in a study released Friday.
