180 COVID-19 vaccines in development, says WHO

Around 180 vaccines to combat COVID-19 are in development worldwide, including 35 in human trials, the WHO chief said on Friday. 'No disease in history has seen such rapid development in research. It's a testament to the incredible advances in science and technology the world has made in recent years,' Director-General Tedros Ghebreyesus told reporters in Geneva. 'It must be matched by its ambition to ensure as many people as possible have access to them.' When journalists asked about differing claims on vaccines' arrival, including an aspiration by US President Donald Trump to have one by October, the WHO's chief scientist Soumya Swaminathan said people should remember that 'clinical trials take time.'
