Moderna says it is a "great day" and they plan to apply for approval to use the vaccine in the next few weeks.

However, this is still early data and key questions remain unanswered.

How good is it?

The trial involved 30,000 people in the US with half being given two doses of the vaccine, four weeks apart. The rest had dummy injections.

The analysis was based on the first 95 to develop Covid-19 symptoms.

Only five of the Covid cases were in people given the vaccine, 90 were in those given the dummy treatment. The company says the vaccine is protecting 94.5% of people.

The data also shows there were 11 cases of severe Covid in the trial, but none happened in people who were immunised.
