For over 165 years, Pfizer has discovered and developed medicines that have saved and improved the lives of millions of people. By helping to eradicate disease and treating illnesses, medicines have provided enormous value to society. Pfizer has long maintained that medicines provide tremendous value to individuals and society as a whole. We have captured that value in a series of concise, easy-to-access papers that detail the societal and economic value provided by medicines that treat various disease areas. The data we provide come from published, peer-reviewed studies and are complemented by real stories from patients who have benefited from medicines. We hope these will serve as a resource to those looking to quantify the value of medicines.
