But Uromune is not a traditional vaccine injected to your arm. So what is it and how does it work? First, what are UTIs? UTIs are caused by bacteria entering the urinary system.

This system includes the kidneys, bladder, ureters (thin tubes connecting the kidneys to the bladder), and the urethra (the tube through which urine leaves the body). The most common culprit is Escherichia coli (E. coli), a type of bacteria normally found in the intestines.

While most types of E. coli are harmless in the gut, it can cause infection if it enters the urinary tract. UTIs are particularly prevalent in women due to their shorter urethras, which make it easier for bacteria to reach the bladder.
