Shedding light on the timeframe, WHO chief scientist Dr Soumya Swaminathan said in a press briefing that effective vaccine distribution can be expected to begin by the middle of 2021.
“So realistically speaking, probably the second half, the middle of 2021 – maybe the second quarter, the third quarter of 2021 – is when we can start seeing doses actually flowing into countries so that they can start to immunize their populations,” she noted.
