Like that of Pfizer / BioNTech, authorized 7 days ago, Moderna’s vaccine uses messenger RNA technique to fight the virus. The vaccine is 94.1% effective, which means that it reduces the chances of contracting Covid-19 by the same amount.

For the two authorized vaccines, the green light from the FDA came the day after the favorable opinion of a committee of American experts. While Pfizer / BioNTech’s remedy had already set a record, Moderna did even better: their vaccine was approved 19 days after the official request was filed, compared to 22 for Pfizer.

100 million people vaccinated by the end of June

The US government has pre-purchased 200 million doses from Moderna (compared to 100 million from Pfizer). The firm has promised to distribute 20 million doses by the end of December 2020, then an additional 80 million in the first quarter of 2021, and the other 100 million in the second quarter (i.e. by the end of June). Since it is taken in two doses spaced four weeks apart, this corresponds to 100 million people vaccinated.

Moderna’s formula can be stored at -20 ° C, and not -70 ° C for the Pfizer vaccine, a temperature much lower than standard freezers and which has forced the group to develop specific containers for transport. “Flaconnage” takes place at subcontractor Catalent in Bloomington, Indiana, where Moderna ships large 50-liter bags of the vaccine, made in New Hampshire.
