overactive bladder, an adverse effect of the vaccine?

Many people vaccinated against Covid-19 report a new side effect, an overactive bladder. Explanations.

More than 52 million French people are fully vaccinated against Covid-19. Over the months and studies, researchers are learning more about the contours of the virus and the potential adverse effects of the vaccine. While not everyone is affected by the same side effects, most vaccinees report pain at the injection site, headache, muscle aches, fever or chills.

But recently, a new vaccine-related side effect was reported by researchers at Kaohsiung University in Taiwan. According to them, the vaccine against Covid-19 could be the cause of urinary tract disorders. Their findings were published in the Journal of Clinical Medicine.

To arrive at this observation, they collected responses obtained through surveys published online. “Participation in this research was voluntary, therefore, the subjects did not receive any financial compensation or other incentives, which minimized information and selection bias”, specify the authors of this study.

Increased urge to urinate

In view of the results, 13.4% of respondents reported side effects concerning the urinary system. The majority of those affected mentioned an urge to urinate and an increased urge to urinate. Others have also reported incontinence following vaccination.

Recently, the National Medicines Safety Agency (ANSM) published an exhaustive list of possible adverse effects following vaccination against Covid-19 with Pfizer and Moderna. In addition to more classic consequences, she now mentions an overactive bladder.
