Coach peers and junior colleagues, sharing best practices and fostering a culture of learning and collaboration.

Manufacturing
Breakthroughs that change patients' lives
Research confirms what intuition tells us: that purpose-driven companies perform better, are more innovative, attract and retain the best people, and know how to unleash the power of those people.
Pfizer's purpose—Breakthroughs that change patients' lives—fuels everything we do and reflects our passion for building on our legacy as one of the greatest contributors of good to the world.
Each word in our purpose has meaning and reflects the value we strive to bring to patients and society:
"Breakthroughs"
- These are the innovations, scientific and commercial, that we seek to deliver every day.
All colleagues, regardless of role, level or location, strive for breakthroughs every day.
"Change"
- We want to do more than simply improve patients' medical conditions; we want to dramatically change their lives for the better.
"Patients' lives"
- We consider not only patients, but everyone they touch—including their families, caregivers, and friends—and everything they love to do.
It's an intentionally holistic view.
Our purpose ensures that patients remain at the center of all we do.
We live our purpose by sourcing the best science in the world; partnering with others in the healthcare system to improve access to our medicines; using digital technologies to enhance our drug discovery and development, as well as patient outcomes; and leading the conversation to advocate for pro-innovation/pro-patient policies.
Every decision we make and every action we take is done with the patient in mind—and to nurture an environment where breakthroughs can thrive.
Our Values
To fully realize Pfizer's purpose, we have established a clear set of expectations regarding "what" we need to achieve for patients and "how" we will go about achieving those goals.
The "how" is represented by four simple, powerful values—courage, excellence, equity, and joy—that define our company and our culture.
Courage:
Breakthroughs start by challenging convention, especially in the face of uncertainty or adversity.
This happens when we think big, speak up, and are decisive.
Excellence:
We can only change patients' lives when we perform at our best together.
This happens when we focus on what matters, agree who does what, and measure our outcomes.
Equity:
We believe that every person deserves to be seen, heard, and cared for.
This happens when we are inclusive, act with integrity, and reduce healthcare disparities.
Joy:
We give ourselves to our work, but it also gives to us.
We find joy when we take pride, recognize one another, and have fun.
Pfizer Global Supply proudly shoulders the responsibility of manufacturing and distributing our wide-ranging pharmaceutical products.
With an unwavering commitment to ensuring the availability and accessibility of these life-saving medications, we play a pivotal role in reaching patients, healthcare professionals, and markets across the globe.
Our network of state-of-the-art manufacturing facilities, strategically located distribution centers , and streamlined logistics systems enables us to deliver Pfizer's medicines with utmost efficiency and reliability, making a tangible difference in patients' lives worldwide.
