Leaders from around the world joined the World Health Organization, after it announced the launch of a new effort to accelerate the development of vaccines, diagnostics and therapeutics in response to the coronavirus pandemic.

Here’s what they’re saying:

Melinda Gates, speaking for the Bill and Melinda Gates Foundation, a co-host of the effort, said, “the moment we are living through right now is a reminder, that we’re all part of the same global community. As new diagnostics, treatments and vaccines become available, we have a responsibility to get them out equitably, with the understanding that all lives have equal value.”

António Guterres, secretary-general of the United Nations said “the world needs development, production and equitable delivery of safe and effective Covid-19 vaccines, therapeutics and diagnostics.”

Giuseppe Conte, prime minister of Italy said, “There is one thing we understand well, finding and distributing the vaccine is the only way to win this battle,” adding, “You can count on Italy, together we will make it.”

Dominic Raab, Britain’s Foreign secretary who has stepped in for Boris Johnson, said “by working together, we can develop an affordable vaccine which is accessible to everyone who needs it, as quickly as possible, to end this pandemic once and for all.”

Cyril Ramaphosa, president of South Africa said, “As now more than ever, the world needs solidarity and cooperation to mobilize and guide all efforts and drive delivery towards equitable access to new Covid-19 diagnostics, therapeutics and vaccines.” Ramaphosa added, “Africa is extremely vulnerable to the ravages of this virus, and is in need of every possible support and assistance.”

Erna Solberg, Norway prime minister said, “We must commit to a system of fair global access, because as long as the virus is active somewhere, we are at risk everywhere.”

Muhyiddin Yassin, prime minister of Malaysia said, “the only way we can destroy this common invisible enemy of ours is through solidarity and cooperation. The world needs to come together to coordinate our efforts and expedite the development of effective tools to stop the spread of this disease.”
