Aug. 25, 2009 — -- Up to half of the population of the U.S. could come down with the swine flu and 90,000 could die this season, according to a dire report from the President's Council of Advisors on Science and Technology.

The report, which claims as many as 1.8 million people could end up in the hospital seeking treatment for the H1N1 virus, comes as government officials push drug companies to make a vaccine available next month.

"It's a plausible scenario that we need to be prepared for," said Marty Cetron, the Center for Disease Control's director of the Division of Global Migration and Quarantine.

The report says that under a worst-case scenario, between 60 and 120 million Americans could get sick with the swine flu and another 30 million could contract the virus but not show symptoms. Between 30,000 and 90,000 could die -- more than twice the annual average of deaths associated with the seasonal flu. Those deaths generally occur in people older than 65.

The swine flu is "unusual," however, U.S. Health and Human Services Secretary Kathleen Sebelius said, because it tends to affect children and young adults more harshly than others and "hasn't yet affected seniors."

The report says the skyrocketing infections will peak on Oct. 15 -- the exact date a vaccine is expected to be delivered. The White House advisors suggest backing up the vaccine date by a full month -- meaning a vaccine and dosage that is still being tested would be used.

"Trying to rush in with an unknown, with an untested quantity of vaccine doesn't appeal to me at all," said Dr. William Schaffner, a professor of preventive medicine at Vanderbilt University.

The council recommended that manufacturers begin to package the vaccine so that it could be used in September by those at high risk. All five manufacturers have already been asked by the government to bottle the vaccine when it's ready.

But health officials announced a delay in the vaccine production last week. Originally, the government expected 120 million doses to be available on Oct. 15, but it now estimates there will only be 45 million, with 20 million more each week through December.
