The general idea of the rich helping the poor, I think, is important. That your sense of justice says, why should rich kids - who barely get these diseases and almost never die of them - why should they get the vaccines, when poor kids, who actually do die from these diseases, don't get those things? It's an unbelievable inequity that there isn't that access.

We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten. Don't let yourself be lulled into inaction.

Is the rich world aware of how four billion of the six billion live? If we were aware, we would want to help out, we'd want to get involved.

I would certainly use my voice to try and avoid anything that undermines confidence, so that parents are using vaccines fully.

How fast a company can respond in an emergency is a measure of its corporate reflexes.
