Clinical trials are the reason we have safe medicines, vaccines, and treatments today. They help doctors and scientists find out if a new treatment works, how well it works, and whether it causes any side effects.

Without clinical trials, we wouldn’t know if a new drug helps people or harms them. That’s why these studies are carefully planned, reviewed by ethics experts, and follow strict safety rules.

Clinical trials also help:

• Improve care for future patients
• Provide access to new treatments before they’re available to everyone
• Prevent or detect diseases earlier

Every trial participant plays an important role in moving science forward and helping others, sometimes even generations into the future.
