Flu vaccine makers delaying deliveries - WQOW TV: Eau Claire, WI NEWS18 News, Weather, and Sports

The largest manufacturers of seasonal flu vaccines in the U.S. are delaying or reducing the number of doses shipped to the country. That's partly because of the crunch to produce millions of doses of the H1N1 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, however, 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.
