Do antibiotics affect vaccine responses?
Treatments studied
Part of Immune system & allergy, Infections clinical trials.
This study looks at whether taking a short course of antibiotics can change how your body responds to two vaccines (BCG and yellow fever). It may help researchers find ways to make vaccines work better.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 35 years old.
- You have never had a BCG or yellow fever vaccine before.
- You are willing to take a short course of antibiotics.
- You are willing to give up to 7 blood samples and 3 stool samples over 5–7 months.
- You do not have serious skin conditions like severe eczema or a weakened immune system.

This study looks at how your body's immune system responds to the yellow fever vaccine. It may help researchers understand how well the vaccine protects people.
This study measures how strongly your immune system responds to COVID-19 vaccines. It includes people with newly diagnosed tuberculosis and a healthier comparison group, aiming to understand vaccine immune effects and safety.
This study looks at how your immune system “remembers” the yellow fever vaccine over time. It may help researchers understand long-term immune protection and how it varies between people.
This study gives (or follows) typhoid and/or cholera vaccines and measures how your immune system responds. It is done in adults who are already scheduled for an upper endoscopy (EGD) and/or colonoscopy, using small tissue samples if appropriate.
This trial tests whether a new vaccine called MTBVAC can prevent tuberculosis (TB) in people living in areas where TB is common. If you are between 14 and 45 years old and in good health, you may be able to join.
This trial checks whether a yellow fever vaccine is safe and works well in adults with HIV who have relatively healthy immune function. It may help doctors understand the best way to protect people with HIV who have never had this vaccine.
