The pandemic will not be under control until about two-thirds of the world's population is immune, and it is likely to last for up to two years.

It writes a group of experts in a report from the University of Minnesota in the United States, according to Bloomberg.

Tegnell: We will have the virus for a long time

According to Anders Tegnell, the virus can remain in the population for a long time, but if the pandemic will continue for two years, he says, it depends on what they mean by "going on".

- We will probably have a long time to come, if we ever get rid of it. What can somehow prevent it is if we get a vaccine, says Anders Tegnell to SVT News.

- But these large, extensive distribution numbers that we are seeing now, I expect that will gradually decrease.

Can come in several waves

Because of the virus's ability to spread from people who are perceived as symptom-free, the virus can be extra difficult to control, the experts say. According to the authors, one can be the most contagious before the symptoms become apparent.

The authors also write that we may need to be prepared for the infection to come in several waves, even after 2022.
