The H1N1 flu virus could cause up to 90,000 U.S. deaths, mainly among children and young adults, if it resurges this fall as expected, according to a report released Monday by a presidential advisory panel. The report urges speedier production of the H1N1 vaccine and the availability of some doses by September. Up to 40,000 U.S. deaths are linked to seasonal flu each year, with most of the fatalities occurring among people over 65. An H1N1 resurgence may happen as early as September, at the beginning of the school year, and infections may peak in mid-October, according to the report. However, the H1N1 vaccine isn’t expected to be available until mid-October, and even then it will take several weeks for vaccinated individuals to develop immunity, the report says.
