The race is for successful vaccines, not just a vaccine. As Dr. Neame mentioned, we need vaccines and we need multiple vaccines. It's not just because of manufacturing capability, but that is clearly one reason. We need multiple companies with multiple facilities to produce vaccines that are going to have a global demand. Also different vaccines and different platforms may turn out to be more effective in different subpopulations. For example, there may be vaccines that work better in the elderly, others that work better in young, healthy adults and others that work better in children.
We need multiple vaccines, so we want to support any vaccine that is successful.
