John Wyeth

Wyeth was a prominent global pharmaceutical company that operated for nearly 150 years before its acquisition by Pfizer in 2009. Originally established as John Wyeth & Brother in 1860, the company became a leader in several therapeutic areas, including vaccines, oncology, and women's health. It was responsible for developing and marketing high-profile products such as the pneumococcal vaccine Prevnar and the blockbuster biologic Enbrel. The company's legacy includes significant contributions to the development of modern drug manufacturing and large-scale vaccine production. Today, its former assets and research programs are fully integrated into Pfizer's global operations.
