CDC urges flu vaccinations amid mounting H1N1 illnesses

With several weeks or more remaining in a particularly deadly influenza season, U.S. health officials on Thursday urged flu vaccinations for everyone over the age of 6 months, including pregnant women.

"Influenza can make anyone very sick, very fast and it can kill," said Dr. Tom Frieden, director of the U.S. Centers for Disease Control and Prevention. "Vaccination is the single most important thing you can do to protect yourself."

This year's illnesses have been caused predominantly by the H1N1 virus — the same "swine flu" strain that caused the pandemic in 2009.

Although officials say the prevalence of flu-related illness this season appears to be lower than in 2009, preliminary reporting suggests that it has killed or hospitalized more young and middle-aged adults than usual — particularly those with existing health problems.

In studies released Thursday, CDC epidemiologists said that based on a national sampling of 122 U.S cities, 61 percent of all flu-related hospitalizations involved adults between the ages of 18 and 64. In the past several years, this rate has been much lower — 35 percent to 43 percent.

While it remains unclear exactly why hospital admissions have increased among young and middle-age people, officials note that they are traditionally the least likely people to seek annual flu vaccinations.

Health officials estimate that only 34 percent of people between 18 and 64 get annual flu shots, while the vaccination rate for people over 65 is 62 percent. The vaccination rate for youths aged 6 months to 17 years is 41 percent.

"This season is hitting middle-age and younger adults hard and the season is likely to continue for some time," Frieden told reporters. "It's not too late to get a flu shot."

Each year, health officials formulate a vaccine that will address those viral strains that are expected to be most active. In this case, they accurately predicted the return of H1N1 and included it in the vaccine.

Although officials insist vaccination is the best, first-line defense against influenza, they acknowledged that some people who get the vaccine will still get ill.

"This year's flu vaccine is working," Frieden said. "It's not working as well as we wish it would."

In reports released Thursday, CDC officials estimated that the vaccine was 62 percent effective.

"That means if you were vaccinated, you are quite likely to be protected from the flu viruses that have been circulating this season," said Dr. Anne Schuchat, assistant surgeon general and director of the CDC's National Center for Immunization and Respiratory Diseases.

"There's a lot of myths and misinformation out there," Schuchat said. "It doesn't cause flu, but some people worry that it might ... the CDC recommends that everyone 6 months and older get a flu vaccine and that includes pregnant women."

In cases where people experienced serious flu symptoms, whether they were vaccinated or not officials urged the use of antiviral medications, which are prescribed by a doctor.

My kids and I get the Flumist - love it. No shots; it's a weakened live virus that's swabbed in your nose. Twice as effective as flu shots for kids.

How many actual cases of H1N1 have occurred? The current vaccines are not really current as they are last years flu strain. This year's flu strain will be next year's vaccination.

That's wrong. The current vaccination protects against H1N1, which is THIS YEAR'S flu that is killing otherwise healthy young and middle aged people.
