Clinical trials

New medicines and vaccines cannot be used straight away. They must first be thoroughly investigated to see whether they are safe and effective. This requires clinical studies. New medicines and vaccines can only be used on a large scale after various test phases have been completed.

The Institute of Tropical Medicine is involved in clinical studies like these. We are researching vaccines and medicines against tropical infectious diseases, but also against diseases that occur worldwide, such as COVID-19, HIV and STIs.

Before you take part in a study, you will be screened to see if you meet all the conditions and you will receive a detailed explanation of the vaccine being tested. You will be given an overview of the possible risks, the benefits and the course of the study.


  • You are 18 years of age or older.
  • You are not pregnant, are not breastfeeding and do not intend to become pregnant.
  • You can easily be reached by e-mail or mobile phone.


Phase 3 COVID-19 vaccine study Janssen Pharmaceutica

We currently have enough candidates for this study. Volunteers are now being invited.

Phase three of a vaccine study mainly tests the effectiveness of the vaccine, i.e. do the vaccines offer sufficient protection and to what extent? It is the final stage in the development of a vaccine before it reaches the market. In the two preceding phases, the safety and tolerances of the vaccine were examined in detail. 

Each participant in the vaccine study is closely monitored by our researchers for a year. A total of 5 appointments are planned.

Both healthy individuals and patients with underlying conditions like asthma, chronic lung diseases, diabetes, cardiomyopathies, high blood pressure, chronic liver disease and other conditions all age groups are participating.
