Sweden has become one of the countries that has managed to maintain low rates of infection with the CCP (Chinese Communist Party) virus (COVID-19), since the pandemic spread around the world. Now leading health experts indicate that the decision not to impose a blockade and to remove the masks has led to the development of herd immunity.
According to Marketwatch, Stockholm University biometrics professor Arne Elofson believes that the population has developed a kind of herd immunity, “strict rules don’t work because people seem to break them. Sweden is fine,” he said.
Anders Tenell, an epidemiologist involved in managing the response to the pandemic in Sweden, said that the masks give a false sense of security. Tenell said, “The belief that masks can solve our problem is very dangerous.”
According to data provided by the Center for Disease Control and Prevention in Europe, Sweden has a biweekly infection rate of 37 cases per 100,000 people, which is lower than other countries such as France with 60 cases per 100,000 people, and Spain with 152.7 cases per 100,000 people.
As reported by the BBC at the beginning of the month, the Swedish economy only contracted by 8.6% in the April-June period compared to the previous three months. In comparison, the European Union had a contraction rate of 11.9% during the same period.
According to the Swedish Prime Minister, Stefan Lofven, the rules of social distancing and avoiding the closure of schools and implementing measures such as banning gatherings of more than 50 people generated a positive impact in containing the outbreak of the CCP Virus.
“The strategy we adopted, I think, is right: protect people, limit the spread of infection,” said Lofven.
The approach adopted by Sweden is gradually leading to a rethinking of strict closures in other countries as well because of the serious consequences for the economy.
According to the Wall Street Journal, “Sweden’s current infection and death rates are as low as the rest of Europe, suggesting to some experts that the country may be close to mass immunity.
According to a study published on Aug. 14 in the journal Science, researchers from Stockholm University in Sweden and the University of Nottingham in the United Kingdom investigated herd immunity and found that it could be achieved with a population-wide infection rate of about 40 percent.
According to the article, human populations are far from homogeneous in terms of age and activity levels. The researchers then created a mathematical model to show how such differences might affect the spread of the disease.
Then, they introduced age differences into the propagation models for the population, finding that the threshold for herd immunity could be reduced by approximately 40% since “the proportion of infected individuals in the groups with the highest contact rates is higher than in the groups with low contact rates.”
“This shift is because transmission and immunity are concentrated among the most active members of a population, who are often younger and less vulnerable,” they said. “If non-pharmaceutical interventions are very strict, no herd immunity is achieved, and infections will then resurge if they are eased too quickly.”
For Nobel laureate in economics Paul Romer, the United States could not decide whether to move toward “mitigation or suppression,” noting that efforts to achieve mass immunity meant accepting that there would be thousands of additional deaths.
He also noted that a total blockade measure “is meaningless unless you are going to continue it for as long as it takes.”
As for the impact of the lockdown on society, Dr. Michael Mina, a Harvard University medical epidemiologist, said that in the United States, “the economy was being damaged, wandering back and forth between right and wrong with a slow change of companies closing their doors forever.”
Mina, together with a team of experts, designed a reopening method based on the frequency of contacts and vulnerability to CCP Virus based on five demographic groups and 66 economic sectors.
