The coronavirus will infect millions who will show very little or no effect from it. From Johan Giesecke at thelancet.com:
Many countries (and members of their press media) have marvelled at Sweden’s relaxed strategy in the face of the coronavirus disease 2019 (COVID-19) pandemic: schools and most workplaces have remained open, and police officers were not checking one’s errands in the street. Severe critics have described it as Sweden sacrificing its (elderly) citizens to quickly reach herd immunity.1
The death toll has surpassed our three closest neighbours, Denmark, Norway, and Finland, but the mortality remains lower than in the UK, Spain, and Belgium.2
It has become clear that a hard lockdown does not protect old and frail people living in care homes—a population the lockdown was designed to protect.3
Neither does it decrease mortality from COVID-19, which is evident when comparing the UK’s experience with that of other European countries.
