St George’s University Hospitals NHS Foundation Trust- Request for Volunteers

Opportunities - 27 February 2026

St George’s University Hospitals NHS Foundation Trust is looking for volunteers to help beat paratyphoid A fever.

On a dark blue image there are various icons arranged in 2 rows - on the top row an online survey, hands raised in the air and speech bubbles; on the bottom row a happy face, a neutral face and a sad face. To the top left corner and bottom right corner are the Healthwatch Surrey speech marks.

If you are aged 18 to 55 years old, and in good health, you may be eligible to take part in the BiVISTA study to find a vaccine against typhoid and paratyphoid A fever.

Participants will be vaccinated with the new vaccine or control, and then exposed to the bacteria that causes paratyphoid fever. All study participants will receive antibiotic treatment.

All participants will be reimbursed up to £4,500 for their time, inconvenience, and travel.
