With Severe Flu Season Lurking, Shots a Must

FRIDAY, Oct. 27, 2017 -- Early signs suggest that the United States will see a severe flu season, so it's especially important for Americans to get their shots, health experts say.

Australia had its worst flu season on record, and what happens in the southern hemisphere typically predicts what happens in the northern hemisphere, said Kevin Harrod. He is a professor in the University of Alabama at Birmingham's department of anesthesiology and perioperative medicine.

"These data tell us that we should see a worse-than-average flu season," Harrod said.

This year's vaccines are combating the H3N2 strain and B strains of influenza, according to Harrod. H3N2 viruses cause more severe disease in the elderly and young children, and they are associated with a high hospitalization rate, he noted.

The best protection against the flu is vaccination, Harrod said in a university news release.

"While getting the flu shot may not keep you from getting the flu, it will limit the severity and duration of the illness, and provide you with some protection against future infections in subsequent seasons," Harrod said.

"Even in years when the flu vaccine is a 'bad match,' there is partial protection because one's immune system can make antibodies that still recognize and bind to the influenza virus even when new strains emerge unexpectedly," he added.

Dr. Leah Leisch, an assistant professor in the division of general internal medicine at UAB, noted that the U.S. Centers for Disease Control and Prevention recommends everyone 6 months and older -- including pregnant women -- get a flu shot.

"It is especially important for people at high risk for flu-related complications. This includes, but is not limited to, pregnant women, children younger than 5, adults older than 65 and people with certain medical conditions," Leisch said.

Harrod said the CDC's Advisory Committee on Immunization Practices does not recommend the use of the nasal spray flu vaccine in the 2017-2018 influenza season.

Leisch had some tips on what to do if you think you are coming down with the flu.
