Many people have questions about flu shot effectiveness. According to experts, one particular group seems to get a weaker boost to their immune system following a flu shot than others.
Experts say the findings essentially confirm what’s been believed: The flu shot just doesn’t work as well for older immune systems. But they also caution that the vaccine remains the best defense against flu misery.
Older people are among those at greatest risk for flu complications, like pneumonia. Americans older than 65 have been hard-hit during the current, rough flu season: Late last month, the U.S. Centers for Disease Control and Prevention said that 98 of every 100,000 seniors were hospitalized with the flu for the week ending Jan. 19.
So older adults should keep getting vaccinated every year, according to Nicholas Kelley, a research associate with the Center for Infectious Disease Research and Policy at the University of Minnesota, in Minneapolis.
