How exercise can boost your immune response to the flu shot

Doing a few push-ups before getting your flu shot could boost the number of antibodies you make against the virus — and if you’re already physically active, that effect could be even greater.

This is the result of an analysis by researchers from the University of Sydney and UNSW, which was the first to compare the effects of a workout before receiving a seasonal flu shot. in physically active people, compared to their inactive counterparts.

The report, published today in the journal PLoS ONE, did not track whether the participants eventually caught the flu, but it did suggest that exercise could benefit one part of the population in particular – the elderly.

The researchers found that young adults between the ages of 18 and 35 generated high antibody levels, regardless of their baseline physical activity levels or whether they had exercised prior to vaccination.

But with each passing birthday, our immune system tends to slow down and be less responsive to vaccines.
