he news from Pfizer and BioNTech that their coronavirus vaccine has proved broadly effective in trials added hundreds of billions of dollars to global stock markets on Monday as investors hopes surged that this medical breakthrough would enable economies to return to normal relatively soon.
The share price of travel companies, leisure firms and real estate companies all jumped.
So too, of course, did the stock prices of America’s Pfizer and Germany’s BioNTech, with the former putting on $15bn (£11.3bn) of value and the latter $4bn.
