Pfizer’s Commitment to Improving Diversity in Clinical Trials: A Quiz

"*" indicates required fields

At Pfizer, diversity and equity are of utmost importance, especially when it comes to clinical trials. It is essential to have people of all backgrounds participate in clinical trials to help reduce health disparities among underrepresented populations and improve the development of medicines and vaccines for everyone.

Do you know that Black Americans account for approximately 13 percent of the U.S. population but make up only 5 percent of clinical trial participants? Furthermore, Hispanic and Latino participants account for roughly 19 percent of the population in the U.S. but make up only 1 percent of clinical trial participants.*

For Pfizer, delivering lifesaving treatments for all means ensuring that the company’s clinical trials accurately represent the diverse communities impacted by the diseases it seeks to treat or prevent. As part of these efforts, Breakthroughs for All™ is Pfizer’s commitment to diverse and inclusive participation in clinical trials through equitable access and practices.
