The World Health Organization said on Wednesday it had received data from Pfizer and BioNTech on the Covid-19 vaccine and was reviewing it for "possible listing for emergency use", a benchmark for countries to authorise national use.Referring to Britain's regulator, the Medicines and Healthcare products Regulatory Agency, it said in a statement to Reuters: "WHO is also in discussions with MHRA on the possibility of accessing some of the information from their assessment, which could expedite WHO’s emergency listing".
Britain approved Pfizer's Covid-19 vaccine on Wednesday, jumping ahead of the United States and Europe to become the West's first country to formally endorse a shot it said should reach the most vulnerable people early next week.
Mike Ryan, WHO's top emergency expert, welcomed the news, adding: "We shouldn't stop, we need more than 3-4 vaccines
"We need to increase production, we need to pull the price down," he told a social media event. "We need a one-dose vaccine."
