I'll be the contrarian. I think it's a difficult challenge. I don't think it's a good or bad idea. I think the reason it's a challenge is that one can see arguing this in the short term very much in favour of trying to just expand global vaccine supply as fast as possible. I understand that and I think we've had precedent for that with HIV drugs previously where drugs have been, I believe, manufactured in India even while on patent, in violation of patents, because it was an emergency. I think there's precedent.
That said, I'm going to go out on a bit of a limb here. These vaccine multinationals are massive companies—you see that manifested in such names as GlaxoSmithKline and Sanofi Pasteur. There's been this sort of merger mania for about 30 years in the vaccine industry, which has resulted in these very large players. A lot of those players are actually filling an important global role. When it comes to manufacturing vaccines, this is not 1910 in Toronto, where you bought a stable and you harvested serum from horses. The quality issues, the potential liability issues and the fact that it costs about a billion bucks a vaccine to bring a vaccine to market make this a challenging business and sort of push it towards very large players. There are advantages to that.
