Jan. 15, 2010 -- The CDC estimates that 55 million Americans became sick
with H1N1 swine flu between April and mid-December 2009 and roughly 11,000
people died of the disease.
These numbers represent a middle range in CDC estimates. The actual number
of swine flu cases could be as low as 39 million and as high as 80 million
cases during this time period, government officials say.
The figures were reported Friday in the CDC's Morbidity and Mortality
The report also included new figures on H1N1 vaccination coverage in the
U.S. between October 2009, when the first vaccines became available, and
By the end of December, an estimated 61 million people, or roughly 20% of
the U.S. population, had been vaccinated.
Slightly less than one in three people in the initial target group received
the vaccine. This included pregnant women, people living in households with
babies under 6 months of age, children and adults ages 6 months to 24 years,
and older adults with certain health conditions.
An estimated 29% of children and teens between the ages of 6 months and 18
years were vaccinated.
There is now plenty of vaccine, and the CDC's Advisory Committee on
Immunization Practices (ACIP) now has no restrictions on who should be
"Now that there is ample supply of vaccine, efforts should continue to
improve vaccination coverage among persons in the initial target groups, as

aged 65 and over," the report states.

intended to be vaccinated and 22% said they probably would be vaccinated.
"The epidemiology of H1N1 influenza over the months ahead is unknown, but
