Waiting for natural immunity to happen, while doing nothing, is too risky indeed. But there is no country in the world right now where something like this is happening. Various measures are being taken to prevent the spread of COVID-19: vaccinations, restrictions. Also, apart from stimulating the immune system to produce antibodies, the vaccines help to prevent people developing severe Covid symptoms. I'm sure the solution is vaccination, but when most people of the world will be fully vaccinated is a big question. Right now it's only 5.5%. Looks like we have 3-4 months of the vaccination process ahead. It's a long time, but the world economy will survive. We can see from the past year that it is strong enough to survive many months of unfortunate events.
Sweden, Brazil and Mexico are some of the countries that tried the herd immunity approach. And look at the condition of these countries right now. All of them have much more deaths from CoVID 19, when compared to the neighboring countries. In case of Sweden, they have reported 14,413 deaths from CoVID 19 till now. On the other hand, the neighboring countries such as Norway and Finland have reported less than 1,000 deaths each. Look at the stark difference.. this is what herd immunity approach did.
Norway's population is 5.328 million, and they have 783 deaths reported.
Finland's population is 5.518 million - 956 deaths.
Sweden with population 10.23 million has 14,413 deaths.
From the data above it's clear that the Swedish model has totally failed. But it's not much of a wonder. When you think you are smarter than the whole world you fail in the end more often than not. It's not people of Sweden to blame, though. I'm sure they would follow the authorities' orders and instructions. It's Sweden's authorities who acted highly irresponsibly.
