Why? The government is rushing to deliver H1N1 swine flu vaccine to states on or around Oct. 15. Vaccination likely will take two shots given three weeks apart. No protection is expected until two to four weeks after the second shot -- around Thanksgiving for those who start vaccination in mid-October.
"We are not going to have vaccine before H1N1 disease gets here because the disease never went away this summer," Anne Schuchat, MD, director of the CDC's Center for Immunization and Respiratory Diseases, said this week at a pandemic flu symposium. "Schools are now opening and cases are appearing. I would expect to see clusters popping up soon."
"I think we're going to have an interesting fall," Steven C. Redd, MD, director of the CDC's Influenza Coordination Unit, said at the symposium.
All relevant branches of the U.S. government are making full-speed-ahead efforts to prepare for a bad flu season, as the new H1N1 swine flu collides with the seasonal flu. But in the end, the government can do only so much.
The rest is up to citizens, says Kathleen Sebelius, secretary of the U.S. Department of Health and Human Services (HHS).
"It is essential people make plans, because we will not have a vaccine available for a few months," Sebelius said at the CDC symposium.
The first part of the plan is to avoid infection:
Wash your hands frequently and thoroughly. Use soap and warm water when available; use hand sanitizer between hand washings.
Avoid close contact with sick people. Close contact means getting within 6 feet of a sick person. If you must care for someone who is ill, minimize close contact.
It's not known whether face masks protect against infection. If you use one, don't slack off on hand washing or avoiding close contact with sick people. Use the face mask properly and throw it away after use.
Get your seasonal flu vaccine as soon as possible. It's safe, and it protects against the three seasonal flu bugs expected to circulate this fall and winter -- even though it won't protect against H1N1 swine flu.
