I'm not sure if AW has referenced this specific study, but it goes along with his posts about antibodies and other aspects driving how long we will retain some immunity from the virus. This is encouraging, at least!
Cellular, or “T-cell,” immunity against Covid-19 is likely to be present within most adults six months after primary infection, a new study said.
Research by the U.K. Coronavirus Immunology Consortium (UK-CIC), Public Health England and Manchester University NHS Foundation Trust has found “robust T-cell responses” to the coronavirus virus six months after infection.
thanks for posting! Yeah, the t cells are like the guard dogs that had been trained in my previous analogy. Once the t cells encounter the virus, they remember how to fight the virus and create antibodies where as the antibodies themselves fade away. The very exciting thing about t cells is the t cells from Sars-Cov-1 patients still recognize the virus nearly 20 years later (as well as the Sars-Cov-2 virus) and will produce antibodies when activated. It's very encouraging regarding long lasting immunity.
The downside is, from my very limited understanding, they don't prevent infection. They just enable the body to efficiently fight it off and do so almost immediately. But they don't activate early enough to prevent the virus from getting into cells early on. How big of a deal that is, I don'tknow. It would certainly prevent the virus from replicating uncontrolled for a week or so and reduce that time to maybe a day thereby limiting the damage it could do....but it's not a true immunity again from my very limited understanding.
Missouri sees one-day COVID-19 case record as hospitalizations continue to rise
Missouri recorded more than 3,500 new cases of COVID-19 Thursday, a new single-day record. The state's total now nears 200,000 since the outbreak began. The 3,553 new cases is a single-day record. The state did report 5,000 cases on October 10, however said that was due to a multi-day backlog in reporting.
The state also recorded 18 new deaths, bringing the death total to 3,106.
Across the state, hospitalizations rose, reaching a new 7-day record.
The state's positivity rate also continued to rise, topping 15% for the first time.
Second wave just came through my office. Was exposed to a positive case indoors but fairly distanced from last wednesday and thursday. Passed him in the hall once. I had a mask on. Don't recall if he did.
A guy in my office isn't feeling well and is asking around (not me) if he should get tested, because he heard it is kind of a pain in the ass to get tested.
If I have to go through a pain in the ass because it was too much of a pain in his ass to get tested, he will have a much worse pain in his ass.
