Seasonal vaccine supplier running behind
Meanwhile: the largest US 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 H1N1 flu vaccine.The pharmaceutical company says it's shipped more than half of the 50 million doses of seasonal flu vaccine ordered by US health care providers.But the French company says additional doses may be delayed.
The United States is facing a shortage of seasonal flu vaccine even before the regular flu season gets into full swing, federal and independent flu experts say.
