The 2007 flu vaccine was an admitted bust. Researchers create each year’s vaccine by guessing, months ahead of time, which three of the many flu strains are likely to cause flu during the upcoming flu season. They guessed wrong in ‘07, leading to an unusually high number of flu cases. What’s in store for the 2008 flu season?
"One of the biggest challenges in the fight against influenza is producing new vaccines every year," said Jesse L. Goodman, M.D., M.P.H., director of the FDA's Center for Biologics Evaluation and Research. "There is no other instance where new vaccines must be made every year."
That’s because the viruses that cause flu are always evolving, combining and mutating into new bugs. Each year, experts from the FDA, World Health Organization, U.S. Centers for Disease Control and Prevention, and other institutions collect virus samples from all over the world. They study the organisms, trying to predict which strains may cause the most illness in the upcoming season. The FDA takes all this information and, in February, picks the three winners. They must pick very early so manufacturers have enough time to make the new vaccines.
It’s still possible that their predictions prove incorrect. But that’s no reason to skip your flu shot. Even if the vaccine doesn’t exactly match the virus that hits your town this fall and winter, it still may reduce the severity of the illness or prevent flu-related complications. It’s especially important for those at high risk for complications, including older Americans and those with a chronic medical condition.
Remember that the flu is nothing to sneeze at. It is responsible for around 36,000 deaths and more than 200,000 hospitalizations each year. Be sure to schedule your flu shot this fall. And while you’re at it, ask your doctor if you need a pneumonia shot too.
