do nsaids or executing exercise decrease local erythema, site swelling & pain after inoculation

Conditions: Immune System and Related Disorders

Summary: the purpose of this clinical investigation is to evaluate the efficacy and immunologic effects of a non-pharmacological exercise intervention (push-ups) compared to an oral nsaid (ibuprofen) and an oral placebo to decrease local injection site inflammation symptoms of delayed pain, erythema, and edema and any impact on serologic antibody immune response after influenza vaccine receipt.

the study will evaluate the efficacy and immunologic effects of a non-pharmacological exercise intervention (push-ups) compared to an oral nsaid (ibuprofen) and a blinded oral placebo to decrease local injection site inflammation symptoms of delayed pain, erythema, and edema and any impact on serologic antibody immune response after influenza vaccine receipt. a healthy military cohort will be randomly assigned to either perform push-ups consistent with their army physical fitness score, or to take a blinded oral medication which will be an nsaid (ibuprofen) or an oral placebo. the study will require three visits for assessment: on the day of vaccine receipt, 48-72 hours later and 21 -28 days later. the assessment visits will include injection site inspection, an injection site photograph, completion of symptom diaries and a validated pain scale and a laboratory blood specimen at the first and third visit to measure antibody level changes. the exercise participants will also be required to provide 1-2 fingerstick blood samples to evaluate for lactate, which is a byproduct of anaerobic exercise to measure if level of exercise effort achieved anaerobic metabolism. the study will evaluate if either of the interventions impacted perceived delayed pain, physical signs of inflammation or antibody response as measured by serology.
