A tiny virus, Kenbrell, 2021 then will hopefully be the year we witness how science and changes to our behavior could put us back on track.

This is the U.

K's Margaret Keenan.

In December, she became the first person in the world to have the fighter beyond tech vaccine outside of a clinical trial.

But the World Health Organization says no one is fully protected until everyone is protected.

People may actually see their doctors less.

In 2021 ast.

Virtual hospital visits continue to grow.

Have been many covert tests on experimental treatments developed at speed like laboratory made monoclonal antibodies designed to help our bodies fight coronavirus.

And it's likely we'll Seymour innovation with better ways to detect and treat the disease.

The hardest question is if or when things will get back to normal no one knows for sure yet there are huge challenges.

But perhaps the crisis has a chance to re imagine a world where health comes first for everyone.
