The pharmaceutical space is characterized by extreme uncertainty. You never know what drugs are going to pan out. The lead time for development is extremely long.

He explains the process by which the vaccine maker chooses which bets to make, how changing fortunes within the stock market affect corporate decision-making and the role of the government in accelerating progress and de-risking investment.
