Anders Tegnell, the behind-the-scenes planner of Sweden’s “group immunization” strategy, said in an interview, “If we face today’s same disease and face the same disease, we will adopt a compromise between Sweden and other countries. “He also said frankly: “The work we have done in Sweden needs to be improved.”

Studies have shown that as of the end of April, only 7.3% of residents in the capital of Sweden, the most severe epidemic in Sweden, had developed antibodies against the new coronavirus. The “group immunization” did not help the population develop a broad immunity.

In addition, Sweden has one of the highest mortality rates in the world, with 43 deaths per 100,000 people, far exceeding neighboring countries Denmark and Norway.
