Researchers are making “good progress” in developing vaccines against Covid-19, with a handful in late-stage trials, but their first use cannot be expected until early 2021, Reuters quoted a World Health Organisation (WHO) expert as saying on Wednesday.
WHO is working hard to ensure fair distribution of the vaccines, but in the meantime it is key to suppress the spread of the coronavirus, said Mike Ryan, executive director of WHO's emergencies programme, as daily new cases around the globe are at near-record levels.
“We're making good progress,” Ryan said, noting that several vaccines were now in phase 3 trials and none had failed, so far, in terms of safety or ability to generate an immune response.
“Realistically it is going to be the first part of next year before we start seeing people getting vaccinated,” he told a public event on social media.
