Coronavirus is spreading around the world, but there are still no vaccines to protect the body against the disease it causes, Covid-19.

Medical researchers are working hard to change that.

Why is a coronavirus vaccine important?

The virus spreads easily and the majority of the world's population is still vulnerable to it. A vaccine would provide some protection by training people's immune systems to fight the virus so they should not become sick.

This would allow lockdowns to be lifted more safely, and social distancing to be relaxed.

What sort of progress is being made?

Research is happening at breakneck speed. About 200 groups around the world are working on vaccines and 18 are now being tested on people in clinical trials.

However, no-one knows how effective any of these vaccines will be.

When will we have a coronavirus vaccine?

A vaccine would normally take years, if not decades, to develop. Researchers hope to achieve the same amount of work in only a few months.

Most experts think a vaccine is likely to become widely available by mid-2021, about 12-18 months after the new virus, known officially as Sars-CoV-2, first emerged.

That would be a huge scientific feat and there are no guarantees it will work.

Four coronaviruses already circulate in human beings. They cause common cold symptoms and we don't have vaccines for any of them."

Hver verður fyrstur ? Heimurinn er glataður til langframa ef ekki verður tekinn einhver sjans.
