Swedish 'group immunity' experiments against Corona 19 continue. Sweden has not closed public places such as schools, kindergartens, restaurants and pubs. Instead of closing and quarantine measures, the virus is spreading as slowly as possible, and the majority are opting for immunity. 'Group immunity' is a term used to refer to a group or groups of individuals who become immune to more than a certain percentage of immunity in a group due to vaccines or infections. How successful was this experiment in Sweden?



I have compared the situation of Sweden to another 'neighborhood', which is too different from that of Denmark. Denmark closed the border and closed schools and shops as Corona 19 spread. It was a different path than Sweden. From April 15th, elementary school and kindergarten were reopened, but meetings of more than 10 people are still prohibited until the 10th of the following month.

In the early stages of the spread of Corona19, Denmark had more Corona19 patients than Sweden. The number of confirmed patients in Sweden is increasing, and now the number of patients in Sweden is almost double that of Denmark.

To date, Corona19 has been killed in 1,937 in Sweden and 384 in Denmark. Given the total population, the number of Corona19 deaths per million in Sweden is 175, far more than 64 in Denmark.

● 87% of Sweden's deaths are

criticized by the health authorities for "loose" containment measures, even within Sweden. The representative thing is that as the damage of the elderly increased, the elderly became the biggest victims of the policy. Sweden's 1,937 deaths are by age group:

Of the fatalities, 1,691 were over 70 years old, accounting for 87.2% of all fatalities. If you expand the range to 60 years or older, 94.9% of all deaths will occur. In Sweden, the capital city of Stockholm, there are hundreds of cases of infection in nursing homes.

Swedish government virologist and documentary director Lena E. Horn said, "The government has to admit that it has failed policy as far as it has been said to protect the elderly." "It's true that we have failed to protect the elderly, but the overall strategy hasn't failed," said Anders Tennel, an infectious disease scientist at the Swedish National Institutes of Health. Tennelle is known for designing the 'collective immunity' model.● "Absolutely one third of Stockholm's population is expected to be infected."

Sweden's public health agency has reported that about a third of the population in Stockholm, the capital, Stockholm, may be infected with Corona 19 by May 1st. The. That's 600,000 people.

Of course, the results of the 'collective immunity' experiment should also be comprehensively examined, including the economic damage caused by the blockade. According to data compiled by Bloomberg News, in Denmark, 31,000 people lost their jobs as of the end of last month due to authorities' containment measures. 

However, from the 'medical' point of view, there are many skeptics about the 'group immunity' experiment. According to the results of recent antibody tests conducted around the world, corona19 antibodies are formed in about 3% of the total population. Previously, epidemiologists predicted that more than 60% of the population would be infected with corona19, which would result in population immunity, compared to the current rate of population with antibodies is much lower than expected. This means that we have not yet reached the level of expectation of 'collective immunity'.
