What’s a clinical trial?Updated: April 13th, 2021
As the World Health Organization (WHO) explains, clinical trials are a type of research that studies new tests and treatments, and evaluates their effects on human health outcomes.
People volunteer to take part in clinical trials to help test medical interventions, and trials are very carefully designed, reviewed, and completed. You can find out more about the clinical trial process from the WHO.
For COVID-19 vaccines, clinical trials were carried out all around the world, in different countries and among people of a whole range of races and ethnicities, ages, with comorbidities and underlying conditions, genders, and more.
You can find out more about what it was actually like to be part of the COVID-19 vaccine trials by watching the videos made by a volunteer who joined the clinical trials in the UK in 2020.
