Hopefully this is good news but the paper is cautionary.Confirmation now that the Karolinska institute study has been peer reviewed and published that community immunity is much higher than indicated by antibody tests.

Given that the data was gathered in May, it's certain that immunity in the community will have moved on apace since then, which would explain the sustained low numbers of new cases in Sweden. It should also be mirrored here ... with outbreaks being in local hotspots from here on, as opposed to the tsunami of infections that we saw in March/April.
It also bodes well for the future. Good news, as the article says, from a public health perspective.
Hopefully this is good news but the paper is cautionary.
"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."
There were 138 admissions to hospital in the UK on 5 August. The Welsh figures are high as they include suspected cases as well.On August 5th there were just 21 hospital admissions in the UK for Covid 19. This from the peak at the end of March of 3099.
Despite more cases being diagnosed (in community testing) ... as many as 1000 in a day this week, it seems that fewer of those are requiring hospital treatment.
In other good news, ICU recoveries were up to 80% in July as doctors have found better ways to treat the seriously ill.
Worth taking a look at one of John Campbell's latest videos, which mentions the Karolinska study plus others. Even if the science goes over your head he discusses the 'headlines' at the beginning of the video so you don't need to stick around for it all.
In vivo studies now confirming early in vitro work and what some scientist have been saying from very early on (to be fair to them).
That's the daily mail for ya. Still all encouraging.There were 138 admissions to hospital in the UK on 5 August. The Welsh figures are high as they include suspected cases as well.

I think the issue is that the figure for the last English day quoted is low as they're waiting for the test results before confirming numbers. So, on 16 August there were 15 'admissions' in England but 39 over previous days. The '15' will increase but admissions are about 20% lower and 10 days agoThat's the daily mail for ya. Still all encouraging.
there is unlikely to be long-term memory to this virus developing from natural infections, meaning that while antibodies may protect people for a relatively short time, a single person who recovers from the disease could get infected again, perhaps six months later, or even multiple times with SARS-CoV-2. This suggests that developing herd immunity [via natural infection] may be difficult.
This finding would likely not affect vaccine-induced immunity, as vaccines do not induce cytokine storms. A vaccine-induced immune response would likely include the development of a germinal center, and the ensuing creation and immortalization of high-quality antibodies that would provide long-lasting protection against COVID-19.
Good news, I'm no virologist but I believe there is a good chance it'll mutate down to something less deadly. Makes sense really, viruses need hosts to survive they are better off keeping them alive.
The fact that the man had no symptoms the second time suggests his immune system protected him from disease, although it did not stop the reinfection.
“This is a textbook example of how immunity should work,” Akiko Iwasaki, an immunology expert at Yale University, tweeted on Monday, referring to the man’s lack of symptoms.
