Thank you very much.
Ms. Silverman, I want to return to your comments at the end of my last period of questioning.
I do think that one of the possibilities here is that governments the world over are showing that they're prepared to take more aggressive action in order to be able to ramp up vaccine manufacturing. It might help. I recognize that there are already efforts within the pharmaceutical industry, but it might help incent more rapid collaboration and a wider extent of co-operation, and it might also play into some of the conversations that are rumoured to be happening at the board tables of some of these companies.
There have been reports that they're already talking about when they could raise the prices of the COVID-19 vaccine. There has been talk about differential pricing: selling vaccines at different costs to different countries, depending on who they are negotiating with.
I wonder if you would want to speak to the question of galvanizing governments at the WTO to show that other options are possible and, as a way of getting leverage with existing manufacturers, to accelerate their attempts to expand within the voluntary licensing system and to keep their prices low.
