A large part of this confusion has been caused by Tegnell and folkhälsomyndigheten (FHM).

Tegnell and folkhälsomyndigheten (FHM) have clarified their strategy as:

Keep the number of infected people down at any one time to not overwhelm the health system.

Groups at risk for severe disease should quarantine themselves.

But they have also repeatedly indicated that they don't want to stop the spread of infection completely.

And that they are not running a strategy aiming at herd immunity, though when most people have been infected there will be herd immunity.

That sort of communication leads to confusion, as the difference between a strategy that aims for herd immunity and one that will lead to herd immunity, at best is purely semantic.
