Like the Pfizer vaccine, the Moderna vaccine also requires a second booster dose. Moderna's second injection occurs 28 days after the first, compared to 21 injections for Pfizer.
It requires loading temperatures of around -20 ° C, similar to a normal freezer.
The injection process carried out by the American company Pfizer and the German BioNTech SE requires temperatures close to -75 ° C, which makes transport logistics difficult.
Moderna is based in Cambridge, Massachusetts, and has previously said that "the vast majority" of its doses will be manufactured there. Pfizer / BioNTech is manufactured in many countries, including Germany and Belgium.
Other countries have requested the Moderna vaccine:
• Canada plans to have 2 million doses by March, part of a total of 56 million doses.
The UK has already ordered seven million doses
Last month, the European Union announced a contract to purchase 80 million doses, with the option to purchase up to 80 million more doses, once the vaccine is deemed safe and effective.
• Japan signed 50 million doses, South Korea ordered 20 million and Switzerland requested 7.5 million, according to Da

Who is the first in the United States?
America's vaccination program aims to reach 100 million people by April.
New York nurse Sandra Lindsay was one of the first people in the country to receive a Coronavirus vaccine when the Pfizer / Bio-N Tech launch began on Monday.
Images of her vaccination were aired on the Twitter account of New York Governor Andrew Cuomo, whose state was the epicenter of the pandemic in the United States in the first wave, earlier this year.
