Seasonal flu vaccine delayed for some U.S. providers

The largest U.S. supplier of seasonal flu vaccines says it's running behind on shipping vaccine for the regular, seasonal flu - partly because of the crunch to produce millions of doses of the swine flu vaccine.

The pharmaceutical company Sanofi Pasteur says it has shipped more than half of the 50 million doses of seasonal flu vaccine order by U.S. health care providers. But the French company has sent notices to customers indicating that additional doses may be delayed.

Company spokeswoman Donna Cary says it could be November before some customers get the rest of their orders.
