Our therapeutic areas

2020 Science Careers Top Employer

We are honored to be recognized as a 2020 Science Careers Top Employer. Thanks to our researchers and scientists, we’re proud to support a culture where ideas can become breakthroughs that change patients’ lives.

Cardiovascular Diseases

Cardiovascular diseases are the number one cause of death worldwide. Our research focuses on investigating potential therapies that treat both the metabolic abnormalities and the heart itself by altering the way it responds to the abnormal metabolic state. Click here to find out more.

Rare disease

Our rare disease team concentrates on therapies for rare disorders. They explore many innovative avenues, including gene therapy and more. Click here to read about the work.


Vaccines are one of the greatest public health advancements of all time. Here, our team translates cutting-edge science into next-generation vaccines. Click here to learn about our vaccines R&D career opportunities.


Our oncology team looks to transform the cancer treatment landscape through meaningful breakthroughs and a robust pipeline of novel cancer medicines. There’s more here.

Working better together

Research partnerships, networks and collaborations allow innovation to thrive. We know we can’t do it alone, so we’re working with everyone from the government and academia to some of our biggest biopharma competitors to get our innovations to patients fast. Our Centers for Therapeutic Innovation (CTI) bridge academia and industry, and we support independent research and quality improvement initiatives to power our guiding purpose – improving patient outcomes.

A robust product pipeline

We’re addressing unmet needs in areas including Oncology, Inflammation & Immunology, Vaccines, Internal Medicine and Rare Disease. Of the 100 products currently in our pipeline, 35 are in Phase 1, 28 in Phase 2, 26 in Phase 3 and 11 are at registration stage. They range from vaccines to small molecule to biologic, and are designed to treat diseases from streptococcal infections to prostate cancer.

Whatever your scientific field, you’ll find your place and feel your impact on global healthcare with us at Pfizer. Learn more about our US R&D sites in the navigation.

How we’re innovating now

Whether it’s leading the way with gene therapy, using breakthrough science to transform cancer treatment, or developing novel anti-infective therapies, we’re right at the cutting edge. We’re even using ‘molecular glues’ and breaking the rules of biology. That determination to do things differently is powering our pipeline: we currently have 100 compounds in development, and 37 of those are in Phase 3 trials or registration.

New therapies

We don’t simply have an eye on the future. We’re creating it. New technology is helping us redefine how we approach the R&D process, we’re developing advanced biotherapeutic medicines that can evade detection by the immune system, and our teams are designing and creating molecules that can change the function of a potential target. Different expertise is essential in innovation, as Jennifer Lafontaine explains here.
