Our commitment to the patient community

We work hard to discover and develop medicines and vaccines that help fight some of the world’s most serious health concerns. And it’s critical that we understand, respect and honor the life experiences of patient communities — your voice is important to us. That’s why we listen to patients and take into account your opinions and perspectives when making business and research decisions.



We put patients at the center of everything we do

We encourage patient communities to become their own health advocates, make informed decisions and be partners in engaging with the health care system.
