Belgium: the heart of GSK Vaccines

Belgium is home to three main vaccine sites for GSK (in Wavre, Rixensart and Gembloux), including the global headquarters of the group's vaccine division. This makes us the largest vaccine manufacturing network in the world.
We ask each of our 9.000 employees working in Belgium to share our mission and to think about how they can help all the patients who rely on our products. To this end, our 2.000 scientists work on researching and developing vaccines every day. 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.
The largest pharmaceutical center in Wallonia
In June 2024, GSK, in partnership with MG Real Estate and Yusen Logistics Benelux, officially opened a state-of-the-art biopharmaceutical warehouse in Gembloux, Wallonia. Spanning 40,000 m², this is the largest logistics center of its kind in Wallonia and across GSK’s global network.
Powered entirely by renewable energy and certified ‘Excellent’ under the BREEAM sustainability standard, the center handles the storage and distribution of millions of vaccine doses and raw materials to over 160 countries. Thanks to advanced technologies such as autonomous mobile robots, automated packaging systems, and high-capacity sorting equipment, up to one million vaccine doses are shipped across the world daily.
The facility is equipped to store up to 42,000 pallets at various temperatures, including a 7,000 m² cold room and a 700 m² freezer compartment. While loading and unloading remain manual, employee workflows are optimized through a goods-to-person system where robots automatically bring products to workers, reducing movement and increasing efficiency.
