What side effects are associated with this type of intervention?

The 9-valent extraintestinal pathogenic Escherichia coli vaccine (ExPEC9V) aims to prevent infections by stimulating an immune response against specific O-serotypes of ExPEC. Common side effects of vaccines like ExPEC9V generally include local reactions at the injection site (such as pain, redness, and swelling), mild fever, fatigue, headache, and muscle aches. Serious side effects are rare but can include allergic reactions. It is important to discuss potential side effects with a healthcare provider to understand the risks and benefits of vaccination.

What prior FDA approvals exist?

There is limited specific information available on prior FDA approvals for treatments similar to the 9-valent extraintestinal pathogenic Escherichia coli vaccine (ExPEC9V) for the prevention of Extraintestinal Escherichia Coli Disease. Generally, vaccines that stimulate the immune response to prevent infections by specific O-serotypes of ExPEC are still under study, and ExPEC9V represents a novel approach in this area. Broader preventive measures for E. coli infections have included general hygiene practices, proper food handling, and in some cases, the use of antibiotics for treatment rather than prevention.

What other types of research exist?

Promising alternatives to the 9-valent ExPEC9V vaccine for preventing Extraintestinal Escherichia Coli Disease include: 1) Probiotics, which have been shown to be effective in preventing Clostridium difficile-associated diarrhea and may offer similar benefits for other bacterial infections. 2) Monoclonal antibodies, such as bezlotoxumab, which have been used to prevent recurrent Clostridium difficile infections and could potentially be adapted for use against E. coli. 3) Other vaccines targeting different bacterial pathogens, which may provide cross-protection or be developed specifically for E. coli in the future.

Pivotal Trial

Summary

This trial tests a vaccine to protect older adults from serious E. coli infections. The vaccine trains the immune system to recognize and fight off nine types of harmful E. coli bacteria. In earlier studies, a similar vaccine caused fever and/or diarrhea in some participants and provided limited protection against illness.

Who is the study for?

Adults aged 60+ with a history of UTI in the past 2 years can join this trial. They must be postmenopausal or sterile if born female, not planning to conceive, and able to use digital devices for communication. Excluded are those with bleeding disorders, certain neuropathies, previous E. coli vaccines, or needing dialysis.

What is being tested?

The study tests whether a vaccine called ExPEC9V prevents invasive diseases caused by certain E. coli types better than a placebo in older adults who've had UTIs before.

What are the potential side effects?

Potential side effects may include reactions at the injection site like pain and swelling, general symptoms such as fever or fatigue, and possibly allergic responses.

Other Research

The ExPEC9V vaccine works by stimulating the immune system to produce antibodies against specific O-serotypes of Extraintestinal Pathogenic Escherichia coli (ExPEC), thereby preventing infection. This targeted approach is crucial for patients as it provides protection against the most common and virulent strains of ExPEC, significantly reducing the risk of invasive disease. Other preventive measures include good hygiene practices and the use of probiotics to maintain a healthy gut microbiota, which can help prevent colonization by pathogenic bacteria.
