Approval of Covid vaccines Happens unlikely before November: U.S health official

Vastavam web: Any Covid-19 Vaccine backed by the Trump administration’s “Operation Warp Speed” program is unlikely to receive a green light from regulators any earlier than November or December, given the time needed for a large-scale clinical trial, the National Institutes of Health director said on Thursday. In a call with reporters, Francis Collins said he thinks testing a vaccine in at least 10,000 people could potentially give enough evidence of safety and efficacy to clear it for wider use.

He added that he is confident that at least one of the six vaccines funded by the initiative will be shown to be safe and effective by the end of the year. Collins expects that the first tens of millions of doses of vaccine produced in the United States will be allocated to those most in need, such as patients at higher risk of complications or front line healthcare workers.
