The American biotech company Moderna announced on Monday in a statement that its vaccine against Covid-19 was 94.5% effective in reducing the risk of contracting the disease, similar to the 90% effectiveness announced last week by the Pfizer / BioNTech alliance.

This means that the risk of falling ill with Covid-19 was reduced by 94.5% between the placebo group and the vaccinated group of the large clinical trial underway in the United States: in this case, 90 participants in the placebo group caught the Covid-19, against 5 in the vaccinated group.
