Vaccination patches could be printed locally. Now, a long-term study is offering hope to those who suffer from bacterial urinary infections.
Over a 9-year period, a British medical team observed the effects of a spray (containing different types of bacteria) administered under the tongue to 72 women and 17 men.
All had suffered previously from UTIs  and took a daily dose for the first 3 months. 54% didn’t suffer another infection in the whole 9-year period.
As a precaution, 40% of participants took an additional dose of the non-prescription vaccine 1-2 years after the last daily one. Significant side-effects were absent and recurring UTIs eased by drinking water.
Wood waste, too, could be equally effective as antibiotics.
