Thank you.
I want to put two scenarios by you, Dr. Lexchin. From an epidemiological and public health infectious disease point of view, if we could immunize all seven billion humans in the next year versus not doing that, but rather, say, immunizing only a quarter of the world and doing the rest over the next 10 years, does that have any impact on the ability of this virus to mutate, or is it beneficial from a public health point of view to do one over the other?
