Team Halo is an effort to support and celebrate the inspiring collaboration between scientists all over the world to help us end this pandemic with safe and effective vaccines. The ‘halo’ represents the ring of connected science that circles the globe. All participation is voluntary. If you’re involved in the vaccine search and would like to be listed on this site, please get in touch. Team Halo was established in partnership with the The Vaccine Confidence Project at the University of London’s school of Hygiene and Tropical Medicine. It is proud to collaborate with the UN Verified Initiative and Gavi, the Vaccine Alliance. Support is provided by Luminate, IKEA Foundation and the Global Challenges Foundation.
