Weight Loss Helps Flu Vaccines Be More Effective
Need another good reason to lose weight? Consider this: If you are obese, the flu vaccine likely will provide significantly less protection against illness. Immune system cells that help fight influenza are less active when you are obese. Over two years, researchers recruited 1,022 North Carolina adults age 18 or older—220 of them with diabetes (primarily type 2)—who had received a flu shot. Nearly 10 percent of the obese participants came down with the flu compared with just over 5 percent of normal-weight participants. People with diabetes and other chronic conditions have a higher risk of serious, and sometimes fatal, flu complications, such as pneumonia.
