A newer flu vaccine may be just as effective as the traditional one but a lot faster to make.

The conventional flu vaccine is produced using chicken eggs to grow the virus. It's a slow process that makes it hard to quickly boost production in response to a pandemic.

The newer flu vaccine is produced using dog kidney cells.

Scientists say such cell culture technology is seen as a somewhat faster and more flexible means of vaccine production.

The vaccine, called Optaflu, is already approved in Europe but not in the U.S.
