The yellow fever vaccine goes a long way in helping you avoid a deadly disease.
It just so happens that yellow fever may not be the only disease you’re preventing with that shot.
The yellow fever vaccine can reduce breast cancer risk by 54 percent, according to a recent study.
While scientists are still looking into the results, the reduced risk of cancer seems to only affect one age group. Only women between the ages of 40 and 54 showed a smaller likelihood of breast cancer years after getting the shot.
