Flu shot doing poor job of protecting older people
ATLANTA – It turns out this year’s flu shot is doing a startlingly dismal job of protecting older people, the most vulnerable age group.
The vaccine is proving only 9 percent effective in those 65 and older against the harsh strain of the flu that is predominant this season, the Centers for Disease Control and Prevention said Thursday.
Health officials are baffled as to why this is so. But the findings help explain why so many older people have been hospitalized with the flu this year.
