4、It’s time to get the first of at least two flu shots recommended for many Americans this fall. Vaccine against regular winter flu is ready.

Despite all the headlines about the new swine flu doctors do expect some garden-variety flu to hit this fall, too. And health authorities on Thursday asked people to go ahead and get that first shot out of the way before the lines start forming for swine flu vaccine next month.

“We must not let our guard down against seasonal flu”, said Dr. William Schaffner of Vanderbilt University.

More than 110 million doses （剂量）of vaccine against regular winter flu are expected this year, according to a new estimate from the Centers for Disease and Prevention. That’s not quite as much as last fall’s record supply. But typically fewer than 100 million Americans get flu vaccine, even though it’s recommended for the majority of the population, including adults 50 and older, all children ages 6 months to 18 years pregnant （孕）women, people of any with health problems like heart disease or a weakened immune system health workers, caregivers of the high-risk including babies younger than 6 months.

Now comes the confusing part.

   The new swine flu, what scientists formally call the 2009 H1N1 strain isn’t hitting older adults nearly as hard—but it’s spreading rapidly among children and young adults, and deaths so far have been mostly among people in their 20s. 30s and 40s.

    The regular flu vaccine won’t protect you against swine flu---that will require a separate shot once that vaccine stats arriving in mid-October.
