The head of the International Federation of Red Cross and Red Crescent Societies (IFRC) has appealed for the world to work together toward a coronavirus vaccine, warning against any unilateral action that could prevent access for poor countries.

“The reality is that there is this risk,” Francesco Rocca, who heads the world’s largest disaster relief network, told Reuters. “Everyone must have access to these lifesaving treatments.

“If someone would say this is the intellectual property of this company ... and putting high prices on the vaccines, so making it impossible or very difficult to have access, this of course can have an impact on the most vulnerable,” Rocca said.
