A common misconception around medical research is that clinical trials are only for the sickest of patients. The truth is that clinical trials can be an option worth exploring for someone who is newly diagnosed with an illness as well as someone who feels their current medicine or therapy is not effective. Yet many clinical trials are in need of people with no serious medical issues. These individuals are called ‘healthy volunteers’ and are often good candidates to help with new vaccine development. People who are healthy can also be participants in trials that are looking at better ways to diagnose illness, trials that are assessing genetic risk for developing illness later in life, or trials looking at the impact of lifestyle changes such as diet and exercise. Worldwide there are thousands of trials seeking healthy volunteers to help advance medical knowledge and know-how. And as with condition-specific research studies, healthy volunteer studies are managed by research professionals, including doctors, with oversight from regulatory bodies to ensure that participants are safe and informed every step of the way.
