The chief medical officer of The University of Kansas Hospital is calling on the public to still get a flu shot this year in spite of a study calling this year’s vaccine only 23 percent effective.

The 23 percent figure came from a study by a publication of the Centers for Disease Control. 

Dr. Lee Norman of The University of Kansas Hospital says the relatively low number was because the primary flu this year had a “genetic drift” from one of the flu strains in the vaccine.

Still, Dr. Norman said an overall 23 percent benefit, while lower than desired still can prevent some flu and cause milder symptoms if you do get the flu.

Dr. Norman says progress is being made in better matching of the flu vaccine.  But, he says the process is still as much an art form as a science.
