About Us

GSK is a science-led global healthcare company with a mission: we want to help people to do more, feel better, live longer.

We have 3 global businesses that research, develop and manufacture innovative pharmaceutical medicines, vaccines and consumer healthcare products.

Belgium is the heart of GSK Vaccines, with three major vaccine sites, in Wavre, Rixensart and Gembloux, including the global headquarters from the vaccines division of the group. That also means we represent the largest industrial network of vaccines worldwide.

+ 2 Million

doses of vaccines are produced every day

We ask each of our almost 9 000 employees working in Belgium to share our mission and to think about how they can help all those patients who rely on our products. For that reason, every day our 1,800 scientists research and develop vaccines. And that is why we have been pioneering new solutions allowing us to make our products available to those who need them, wherever they live and whatever their ability to pay.
