Pfizer

Pharmaceutical giant Pfizer develops and produces medicines and vaccines for a variety of chronic diseases and conditions. The company, founded in 1872, has several blockbuster products that each generate more than $1 billion in revenue per year, including Prevnar 13, a pneumococcal conjugate vaccine; Ibrance, a breast cancer treatment; and Eliquis, which helps prevent strokes in at-risk people. On Dec. 11, 2020, to help combat the coronavirus pandemic, the U.S. Food and Drug Administration authorized Pfizer and BioNTech’s COVID-19 vaccine for emergency use, the first of three given a green light in the U.S. As of May 26, half of all adults in the U.S. have been fully vaccinated against COVID-19, in large part due to the Pfizer-BioNTech shot.
