Pfizer is known for developing medications and vaccines, and for manufacturing them at dozens of factories around the world. Its treatments span a broad range of areas such as oncology, cardiology, and neurology. Among its most high-profile medications are the impotence drug Viagra and the cholesterol treatment Lipitor, which is considered the bestselling drug of all time. During the COVID-19 pandemic, Pfizer developed a landmark and highly profitable vaccine in collaboration with the startup BioNTech; it also developed a treatment for COVID infections, which was sold as Paxlovid. Pfizer was founded in 1849 by immigrants in New York City, which remains the site of its global headquarters.
