GlaxoSmithKline (GSK) Pharmaceuticals and Consumer Healthcare

GlaxoSmithKline, now officially known as GSK, is a global leader in the pharmaceutical, vaccine, and consumer healthcare industries. The company's origins are rooted in a series of mergers involving historic entities such as the London-based Plough Court Pharmacy (founded in 1715) and the New Zealand-founded Glaxo. The modern iteration of the company was solidified in 2000 through the high-profile merger of Glaxo Wellcome and SmithKline Beecham.

GSK operates a vast global supply chain with manufacturing facilities located in many countries, including the United Kingdom, the United States, Belgium, Italy, and Singapore. While it remains a British-headquartered multinational, its production footprint is truly international to meet global healthcare demands. In recent years, the company has undergone significant restructuring, most notably the 2022 demerger of its consumer healthcare business into a separate entity called Haleon, allowing GSK to focus exclusively on biopharmaceuticals and vaccines (such as the AS03 adjuvant used in global health responses).
