The biggest manufacturers of seasonal flu vaccines in the U.S. are delaying or reducing the number of doses shipped to U.S. -
partly because of the crunch to produce millions of doses of the swine flu vaccine.
Sanofi Pasteur says it has shipped more than half of the 50 million doses of seasonal flu vaccine order by health care providers. But the company sent notices to customers indicating the rest may not arrive until November. Novartis and GlaxoSmithKline say their shipments are on schedule. But they've told customers they may get about 10 percent less than originally ordered. Some delays have caused doctors to turn away parents seeking seasonal flu vaccines for their infants and toddlers.
Other public health offices have canceled vaccination clinics.
