Influenza vaccine effectiveness
The influenza vaccine effectiveness was tested amongst those who participate in aerobic exercise three times a week between the ages of 20-35. The test was designed to see if training affects the immunity response. The subjects were immunized with trivalent influenza vaccine prior to their workout and afterward. Researchers stated that there is no association between healthy behaviors, such as proper diet and medical care, and exercising that improved there immune response (Kohut 2004). The study took place in two influenza seasons. The first season was during the fall season and would end during the start of spring, and the cycle would repeat itself. However, before the exercise intervention, subjects would take a 4-week break at the beginning to allow their bodies to adjust from moderate movement to actively moving.
Reporting influenza:
Every 2 weeks throughout the first influenza season, subjects were asked to report any symptoms of illness (fever, aches, chills, fatigue, sore throat, scratchy throat, runny or stuffy nose, cough) and duration of illness. (pg. 2298)
Subjects reported their illness as soon as it began, this typically was reported at the same time the activity intervention began (4 weeks after immunization). These patients would proceed with these reportings until the end of the influenza period in April. Subjects with signs of the infection were asked to report to a neighborhood clinic for a diagnostic testing of influenza.
