Being in a good mood on the day that you get your flu shot could make the shot more effective, suggests research in Brain, Behavior, and Immunity. Researchers followed 138 adults older than 65 for two weeks before they got the shot and four weeks afterward, asking them three times per week about their moods, anxiety, sleep and physical health. Participants who were in a good mood on the day of the shot had more flu antibodies in their blood four and 16 weeks after the shot–in fact, mood accounted for between 8 and 14 percent of the variability in antibody levels.

The fly vaccine may offer more protection to someone who is in a good mood on the day he or she gets the shot.
