Women weren’t
in U.S. clinical research until June 10,


In 2024,
we’re still decades behind.

That’s why Evvy made June 10 into Equal Research Day.

A day to promote inclusive research, tell our stories, and raise awareness for the gender health gap.

About Evvy

What does it mean to be left
out of clinical research?

Until 1993, women weren’t
required in U.S. research for cancer, heart disease, Alzheimer’s, diabetes, vaccines, prescription drugs,
mental health conditions, and
 much more.
Why were women left out?

What happened in 1993?

On June 10, 1993, Congress passed the NIH Revitalization Act, requiring the inclusion of women in clinical research for the
first time.
But on June 10, 2024, we still haven’t reached parity.
Who is still underrepresented?

Women1 are diagnosed on average 4 years later than men across 770+ diseases.2

We’re more likely to die from heart attacks, react poorly to prescription drugs, and have our pain and symptoms dismissed by doctors.

  1. Wherever we cite scientific research, we match the exact language of every study we cite to ensure accuracy (i.e. if the study uses the term “female” or “women” then so does this campaign.) We note that most research to this day does not take an intersectional approach to sex and gender.  However, the intent of the Equal Research Day campaign is to shine a light on all groups who have been underrepresented in clinical research — trans and non-binary people, people of color, people with disabilities, older adults, pregnant people, and more.
