There's growing evidence around the U.S. that the flu jab offers only marginal protection against the seasonal ailment. In Texas, doctors say this year's flu vaccine guarded against less than 30 percent of all flu viruses. The vaccine, which is revised every year to make it as effective as possible, usually works against 70 percent to 90 percent of all the viruses in circulation. Across the country, physicians are reporting an efficacy rate of around 50 percent. Lower response rates are likely to generate a large crop of misery.
"If this vaccine is not working as well as we'd hoped, it has the makings of being one of the worst years for flu," Dr. R. Doug Hardy, infectious disease specialist at Children's Medical Center Dallas and UT Southwestern Medical Center, told the Dallas Morning News.
