Officials from the Centers for Disease Control and Prevention say not enough American adults are getting vaccinated against the flu.
The CDC says the nation will probably fall short of the immunization-rate goals it set for the year 2010.
Gary Euler, an epidemiologist with the CDC, says the reasons include recurring vaccine shortages and a failure to educate older Hispanics about the importance of vaccinations.
The government set 2010 goals of a 90 percent flu vaccination rate for people 65 and older, and 60 percent for younger adults who have high-risk conditions.
Euler says the rate for senior citizens was 64.6 percent in 2004, down from 65.6 percent the year before.
For adults 19 to 49 with high-risk conditions, the rate rose to 26 percent in 2004, up from 24.2 percent in 2003.
But the rate for adults ages 50 to 64 dropped to 45.5 percent, from 46.3 percent.
CDC officials are hoping for a better vaccination campaign this fall.
