GSK's global vaccine headquarters is in Belgium with 7,800 employees. Our research and development activities and our 14 manufacturing sites are spread throughout the entire world.
Our portfolio comprises 30 marketed vaccines and more than 20 candidate vaccines in development. One-third of vaccine candidates in our pipeline target diseases particularly prevalent in the developing world, including all three WHO infectious disease priorities: HIV, malaria (Phase III results published in 2011) and tuberculosis. We are committed to providing vaccines to everyone who needs them, no matter where they live.
Last year, we distributed 1.1 billion doses of our vaccines in 173 countries. This represents approximately 3 million doses a day. Over 80 % of these doses went to developing countries, where they are supplied at prices as low as 10-20 % of those in developed countries. We are one of the main suppliers of vaccines to organisations such as UNICEF and the Pan American Health Organisation (PAHO).
GSK's vaccines business put the customer at the heart of everything we do. That is why we define our vaccines mission as Protecting.Human.Kind.
