Some good new from Sweden, we have not had a COVID-19 death for 7 days now

8. I cannot make that call, as I do not know the viral penetration rate, but here is another article

with some potential good news.


Immunity to COVID-19 is probably higher than tests have shown

A new study from Karolinska Institutet and Karolinska University Hospital shows that many people with mild or asymptomatic COVID-19 demonstrate so-called T-cell-mediated immunity to the new coronavirus, even if they have not tested positively for antibodies. According to the researchers, this means that public immunity is probably higher than antibody tests suggest. The article has been published in the esteemed scientific journal Cell.

Robust T cell immunity in convalescent individuals with asymptomatic or mild COVID-19

SUMMARY

SARS-CoV-2-specific memory T cells will likely prove critical for long-term immune protection against COVID-19. We here systematically mapped the functional and phenotypic landscape of SARS-CoV-2-specific T cell responses in unexposed individuals, exposed family members, and individuals with acute or convalescent COVID-19. Acute phase SARS-CoV-2-specific T cells displayed a highly activated cytotoxic phenotype that correlated with various clinical markers of disease severity, whereas convalescent phase SARS-CoV-2-specific T cells were polyfunctional and displayed a stem-like memory phenotype. Importantly, SARS-CoV-2-specific T cells were detectable in antibody-seronegative exposed family members and convalescent individuals with a history of asymptomatic and mild COVID-19. Our collective dataset shows that SARS-CoV-2 elicits robust, broad and highly functional memory T cell responses, suggesting that natural exposure or infection may prevent recurrent episodes of severe COVID-19.


Also, here is a month and half old article that says back then as many as 40% here in Stockholm may have immunity, warning, it is in Swedish


FHM: Stockholm may have 40 percent immunity

English summary

The corona spring has been long, and it is not over yet. But now comes actually some positive news.

The number of deaths per day remains at a low level, and the number of people who are forced to receive intensive care is steadily declining.

Now there are also new figures from the Public Health Agency which indicate that very many Swedes can be immune to the virus.

FHM’s CEO Johan Carlson tells Dagens Nyheter that around 20 percent of Stockholmers may have developed antibodies. About the same number can carry so-called t-cells. This would mean that 40 percent in Stockholm are immune to the coronavirus.

– It is of course very positive. This gives fairly high immunity values, where we may have up to 40 percent immunity in Stockholm, which is important to slow down the rate of spread. There is much to suggest that it is that way, says Johan Carlson DN.
