German Health Minister Jens Spahn has called on China to make it possible for investigations into the origins of the Covid-19 pandemic to continue, saying more information was needed.

Speaking during a visit to the World Health Organisation headquarters in Geneva, Spahn also announced a €260 million donation to WHO's ACT-Accelerator programme, which aims to ensure the entire world, including poorer countries, receive coronavirus vaccines and tests.

“I call on China to make it possible for the investigations into the origins of Covid to be continued,” he said.
