...speed things up is to toss out the eggs and grow the viruses in human cells. Any virus that can infect humans will, by definition, grow easily in human-cell cultures, so that step could cut the incubation time to three months. Chiron, one of the world's leading manufacturers of the egg-dependent flu vaccine, is testing its first cell-culture technique, which it plans to apply to seasonal and pandemic flu vaccines. The Department of Health and Human Services last spring awarded a $97 million contract to Sanofi-Aventis, a Paris-based drug company, to develop avian...
...current threat of avian flu may have passed before the next-generation vaccines make it to market, the work won't be wasted.

The purpose of the Snuppy experiment is clearly to put a cuter, more approachable face on the use of cloning technologies in humans.
