A new mouth-spray vaccine reportedly stops urinary tract infections (UTIs) from coming back again and again, as can happen in many people prone to the condition.
The pineapple-flavored vaccine, called Uromune, has so far been tested in one study without a placebo group and one completed gold-standard clinical trial. Both studies suggest that, for more than half of the participants, the vaccine helped ward off recurrent UTIs for months. It will need more testing to be fully approved but shows promise.
