Your Mood Could Affect How Your Body Responds To Flu Shot

BOSTON (CBS) - Thrilled to get a flu shot?  Probably not.  But as it turns out, your mood could affect how well your body responds to the medication.

Researchers looked at which factors might improve a senior's immune response to the flu vaccine like diet, physical activity, sleep patterns, and mood.

They found that a person's outlook on the day of vaccination had the greatest impact, with a good mood increasing antibody levels to the flu by 8% to 14%.

If, however, you never have a sunny disposition or if you're not feeling particularly cheery on vaccination day, go ahead and get your flu shot.  Don't delay until you have a pep in your step.
