CTV.ca | U.K. lab may have found fix for low flu vaccine yield

A British laboratory may have found a fix for the low yield problem that has been plaguing companies making swine flu vaccine.

The National Institute for Biological Standards and Control says it is ready to ship new versions of its vaccine seed strain to manufacturers as of today.

The lab's principal scientist, John Wood, says early work with the new version of the seed strain shows it generates a virus yield that's on par with what manufacturers get in seasonal flu vaccine production.
