Diversity in clinical trials
We’re committed to helping people from all backgrounds address their health needs and ensuring that our research reflects the people we serve.
Why is diversity in clinical trials so important?
Different people may have different reactions to the same medicine based on their age, gender, weight, race, ethnicity and other factors. Clinical trials rely on volunteers to participate, and they can help show if the medicines and vaccines are safe and work well for people from all different communities.
Participants in our clinical trials in 2022, at a glance:
More than 88,000 participants enrolled in our clinical trials worldwide
Approximately 50% of our clinical trial participants were from historically underrepresented groups — both in the U.S. and globally
What we’re doing to increase diversity and inclusion in clinical trials
It’s critical that we enroll a broad and diverse community of people in our clinical trials, including individuals from underrepresented groups. People of different ethnicities or nationalities. Women, children and men. People of varying ages. LGBTQI+. People from different socioeconomic backgrounds.
Our recruitment process continues to evolve so that our clinical trials achieve the appropriate participant representation to help us safely bring new medicines to all people.
To ensure historically underrepresented groups are included in our research, we're:
