"cytotoxic T-cell responses participate in the clearance of virus from recovered SARS patients
and contribute to immunopathology in early stages of the disease"

:study: Re: https://directorsblog.nih.gov/2020/07/2 ... -covid-19/

"Much of the study on the immune response to SARS-CoV-2, the novel coronavirus that causes COVID-19, has focused on the production of antibodies. But, in fact, immune cells known as memory T cells also play an important role in the ability of our immune systems to protect us against many viral infections, including—it now appears—COVID-19.

An intriguing new study of these memory T cells suggests they might protect some people newly infected with SARS-CoV-2 by remembering past encounters with other human coronaviruses. This might potentially explain why some people seem to fend off the virus and may be less susceptible to becoming severely ill with COVID-19."

:scratch: A clue that T-cells need to be effective early stage defense ...
to avoid later stage complications (e.g, aggressive immune response). :?:

More research :stars: ...

:study: Re: https://www.frontiersin.org/articles/10 ... 00678/full

"Vaccination strategies that include the induction of virus-specific CD8 T cell responses, either alone or in combination with humoral immunity, may be advantageous by providing many benefits associated with cellular immune responses. CD8 T cells are critical for the elimination of virus-infected cells, and viral clearance was prolonged in the absence of CD8 T cells following acute respiratory virus infections."

:study: Re: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3303224/

"CD8+ T Cells: Foot Soldiers of the Immune System"

"Even after leaving the central lymphoid organs and trafficking via the blood to the peripheral site of infection, CD8+ effector CTL continue to engage in antigen-specific interactions that (apart from resulting in cytolysis of infected targets) drive further proliferation and cytokine release."

:idea: A clue that good blood circulation is required to move the new T cells to the infection sites (organs, tissues, etc.). ;)

:study: Re: https://www.nytimes.com/2020/08/16/heal ... odies.html

"Scientists See Signs of Lasting Immunity to Covid-19, Even After Mild Infections"

"What has been observed in people who fought off mild cases of Covid-19 might not hold true for hospitalized patients, whose bodies struggle to marshal a balanced immune response to the virus, or those who were infected but had no symptoms at all. Research groups around the world are continuing to study the entire range of responses. But 'the vast majority of the cases are these mild infections,' said Jason Netland, an immunologist at the University of Washington and an author on the paper under review at Nature."

:idea: This paragraph suggests that only those who had mild infection (with symptoms) have detectable herd immunity - asymptomatic people and hospitalized patients may not have herd immunity. However, asymptomatic (infected) people must have had effective immune response to remain asymptomatic! Perhaps, mildly infected people and asymptomatics have the same immune response, but the "debris" of only mild infection is still detectable in those studies. :roll:

:study: Re: https://www.japantimes.co.jp/news/2020/ ... infection/

"Hong Kong reports first coronavirus reinfection"

"The 33-year-old’s second SARS-CoV-2 infection was detected via airport screening on his return to Hong Kong from Europe this month. Researchers at the University of Hong Kong used genomic sequence analysis to prove that he had been infected by two different strains. The information technology worker didn’t develop any symptoms from his second infection, which might indicate any 'subsequent infections may be milder,' the researchers said."

:idea: This suggests that a vaccine targeting one strain may not be so effective against another strain. However, it may be somewhat protective, depending on one's immune response in both cases. Unfortunately, "asymptomatic" the second time may still mean "contagious" (once more).

"Renowned European scientist: COVID-19 was engineered"

"It will not be possible for the Dr. Fauci’s of the world to dismiss Professor Giuseppe Tritto as a crank. Not only is he an internationally known expert in biotechnology and nanotechnology who has had a stellar academic career, but he is also the president of the World Academy of Biomedical Sciences and Technologies (WABT) ... a man of considerable stature in the global scientific community." 8)

:bana: Good reading to end the mystery of source, but the critters escaped long ago (relative to "pandemic") and life goes on, making good progress all over the globe (when societal virus control participation is serious & significant). Whereas, the research (and where) is becoming well known, it's alleged military detour will probably remain unproven ... if those who know can keep enforcing the secrecy. :roll:

"a small study suggests, providing a clue to why COVID-19 tends to be more severe in men. Among 98 mostly older adults who were hospitalized with mild or moderate COVID-19, women overall had more 'robust' and 'sustained' attacks on the virus by their immune systems' T cells, researchers reported on Wednesday in Nature. Poor T cell responses in men were linked with worse outcomes"

"There were also gender differences in production of signaling molecules - known as chemokines and cytokines - that recruit immune cells to sites of inflammation. On average, men had higher levels of these molecules, but when women did have high levels, they tended to do poorly ... Men may benefit from therapies that boost their T cell responses, whereas women may benefit from therapies that dampen the signaling molecule response"

"Maine overnight camps hosted over 1,000 kids and counselors, and only 3 contracted the coronavirus."

"By assigning campers and counselors to small, stable cohorts, the camps cut down on scenarios that could spread the virus and set clear expectations for mask-wearing. Those cohorts acted essentially and functionally as family units. The groups initially quarantined together, and campers were allowed to not wear a mask while within their cohort."

"The cohorts dined together, bunked together, and used the same bathrooms. The camps limited mixed-cohort indoor activities where the virus might spread, and encouraged sports that allowed physical distance between cohorts, according to the CDC report. Blaisdell said the camps were able to create a 'culture of compliance' around mask-wearing within the larger camp community, and they didn't have any issues with people not wearing masks."

"In the eight months since scientists identified the coronavirus, we're still learning how its many symptoms can ravage the body. The one thing doctors know for sure is that it can attack any and every cell of the body so there isn't one symptom that connects the dots to one or another treatment that will be effective for everyone." :o

"Farmers Fresh Market supporters rallied outside the Ignacio grocery store Saturday in a show of support for the store’s free-choice mask-wearing policies. But Farmers Fresh continues to violate a public health order intended to reduce the spread of the coronavirus."

:idea: Apparently, only those infected with the coronavirus need to wear masks (according to months of worldwide feedback on how to best control the virus). But no-mask asymptomatics would not know of their infection, so shopping by proxy (or elsewhere) is best for those "at risk". ;)

:study: Re: https://www.dailymail.co.uk/health/arti ... study.html

"An unnamed 25-year-old man from Reno, Nevada, first tested positive in April after developing a mild illness including a sore throat and headache. In May, he fell sick again, but this time developed more severe symptoms of COVID-19 such as a fever and dizziness"

"He tested positive on April 18. His symptoms resolved by April 28 and he received two two negative tests on May 9. Just a few weeks later, on May 31, the man reported symptoms including all the symptoms he had before as well as a fever and feeling dizzy. Five days later, the patient's condition worsened so much that he was hospitalized, and tested positive for SARS-CoV-2 (COVID-19)."

"Bloodwork run by hospital staff showed that the man had antibodies against the virus."

:idea: This second infection within a few months suggests (IMO) that the first infection did not resolve ... despite the two negative tests. Perhaps, medical intervention more than his immune system was the explanation for the seeming first recovery? Or testing is not precise enough to know that infection still lurks? Or ... :?:

And having antibodies against the virus only proves that the immune system is aware of coronavirus presence. This may relate to a vaccination not being sufficiently effective to prevent a bout of seasonal flu. ;)

"If you don't have a system to track, trace and quarantine localized clusters, it's really difficult. This virus is very contagious"

" 'I don't think the country can survive another lockdown. And to be frank, there is no reason to,' said Ranieri Guerra, a World Health Organization assistant director general who is advising the Italian Health Ministry. 'It's very unlikely we'll see anything like it was in the past.' "

:idea: A brief recap of the news about the coronavirus ...

It is "very contagious" and still spreading wherever it exists ... when permitted by society. On the other hand, management of this virus is better now - worldwide - with fewer deaths, partly because of slowly increasing herd immunity ... apparently. Those "at risk" need remain cautious since complications from an infection can still be deadly. And some of those not at risk (including the young) are still vulnerable ... apparently. ;)

"Research Shows Coronavirus Vaccine May Not Work on Obese People"

"Obesity carries a number of risks when it comes to COVID-19. New research from the University of North Carolina at Chapel Hill shows that obese people are 48% more likely to die of COVID-19, and more than double may land up hospitalized. The recent study found that the excessive sugar in the blood, and excess swelling of blood vessels of those who are obese may interfere with immune cells, which makes them poor candidates for a vaccine."

:idea: Considering that a vaccine might help - when no alternative exists - even "poor candidates" are still candidates! Besides, NO vaccine - worldwide - has yet been LARGE-group proven to be effective for months. Also, blood vessel swelling might be moderated with blood thinners, etc., benefiting both vaccine-generated antibodies and distribution of such anti-viral components when the time arrives.

Bottom line: Inflammation is common to many diseases, well known by medical experts, and has long-proven solutions. 8)

[a comment] "Of course it is in the air. Along with everything else. The coronavirus is 100 nm in diameter. In other words, 3.5 million billion of them can fit in a teaspoon. A new virus dies out, when people become immune and no longer spread it. All the talk of vaccines is useless, most of the immunity is generated by T4 cells, which will not be activated by a vaccine. And, the virus continues to mutate, like they all do. That is why there is no vaccine against the common cold."

:idea: Interesting comment, but overstating* "useless vaccines" (science proves that vaccines work ... but not perfectly). Besides, what happens when the virus to which people have become immune dies out ... after it has mutated? How do people get immunity to the mutation? Only from T4 cells? Varying rates of infection - worldwide - suggest varying levels of immunity (or none significant) are generated by humans.

* "no longer spread it" is understatement! (people are still spreading this virus) ;)

Bottom line: Get a good immune system ... and maintain it! Comorbidities are counter-productive - avoid them!
