Infectious Disease

Taking on infectious disease.

We are passionate about working with organizations developing antimicrobial compounds and vaccines pushing barriers of what medicine can do. And we’re as invested as you are in your antibacterial, antivirus, and antifungal clinical development.

Acting as a caring guide, we can help you move through every point in the process – from molecule to market. Over the years, we’ve grown deep understanding of a vast range of therapeutic areas, including HIV/AIDS, hepatitis B and C, cystic fibrosis, septicemia, skin infections, and more.

Parexel's global teams stay on top of the latest in clinical development and can help guide your projects with special knowledge working with hospitalized patients and preventative vaccines.

We have experts in virology, infectious disease controls, GMP, facilities design and bioengineering. Our 1000+ consulting team includes 80+ former regulators / inspectors and public health professionals that have worked on global public health crises including SARS, H1N1, MERS and Ebola, along with industry consultants with in-depth GxP/cGMP compliance experience.
