Sweden is among the countries that have decided versus a lockdown and rather opted for voluntariness when it comes to measures against spreading covid-19 This method has arguably lead to one of the greatest per capita death tolls in the world, however very little resistance.

Antibody tests are only just starting. And a new wave of infections could strike.
Catching the coronavirus can result in resistance, but vaccination would be safer than natural immunization. Yet a vaccine stays imaginary. And it’s neither clear whether those contaminated with the coronavirus really are immune, nor for the length of time.
