Moderna's vaccine against Covid-19 is safe and effective, said Tuesday, the American Medicines Agency (FDA) paving the way for its emergency authorization in the United States by the weekend.

The Moderna vaccine does not present "any specific safety problem identified that would prevent the issuance of an emergency authorization", according to the FDA, which an expert committee is due to meet on Thursday.

Nearly 20 million Americans vaccinated before 2021

If approved, Moderna's vaccine, whose efficacy has been evaluated at 94.1% by FDA experts, will join that of Pfizer / BioNTech in the US vaccination campaign, the largest in history the United States.

The American authorities plan to vaccinate some 20 million Americans before the end of December and 100 million before the end of March.

The United States has purchased a total of 200 million doses of this vaccine from Moderna, half of which is not expected to be distributed until the second quarter of 2021. It has also purchased 100 million doses of the vaccine developed by the Pfizer alliance / BioNTech.

A week behind the Pfizer vaccine 

Initially, the vaccines will be administered as a priority to the most exposed caregivers and residents of retirement homes.

The Moderna vaccine authorization process follows with a week's delay that of the Pfizer / BioNtech vaccine, which received the green light from the FDA last Friday.

More than 300,000 people have died from Covid-19 in the United States, according to the Johns Hopkins University count.

The world's leading economic power continues to record record after record, regularly exceeding 200,000 daily cases and 2,500, or even 3,000, deaths per day.
