About Pfizer

Pfizer was founded in 1949 in Williamsburg, Brooklyn by German-American cousins Charles Pfizer and Charles Erhart as a fine-chemicals business. It gained prominence during WWII by mass-producing penicillin for Allied forces using deep-tank fermentation.

Headquartered in New York City, Pfizer generates over $58 billion annually. The company focuses on mRNA vaccine development, oncology, rare diseases, immunology, and metabolic health. Pfizer co-developed Comirnaty (mRNA COVID-19 vaccine) with BioNTech and acquired cancer therapy specialist Seagen in 2023.
