Blood samples from recovered patients suggest a powerful, long-lasting immune response, researchers reported.

Eight months after infection, most people who have recovered still have enough immune cells to fend off the virus and prevent illness, the new data show. A slow rate of decline in the short term suggests, happily, that these cells may persist in the body for a very, very long time to come.

The research, published online, has not been peer-reviewed nor published in a scientific journal. But it is the most comprehensive and long-ranging study of immune memory to the coronavirus to date.

“That amount of memory would likely prevent the vast majority of people from getting hospitalized disease, severe disease, for many years,” said Shane Crotty, a virologist at the La Jolla Institute of Immunology who co-led the new study.

In the back of my mind is thinking "Not enough info yet.  We'll see"  The front of my mind is thinking "Woohooo!"

COVID-19 reinfection unlikely for at least six months, study finds

During the study, 89 of 11,052 staff without antibodies developed a new infection with symptoms, while none of the 1,246 staff with antibodies developed a symptomatic infection.

Staff with antibodies were also less likely to test positive for COVID-19 without symptoms, the researchers said, with 76 without antibodies testing positive, compared to only three with antibodies. Those three were all well and did not develop COVID-19 symptoms, they added.

Thanks, how'd you do that? I've tried a few times with no success.

I have a couple of relatives involved in an antibody study currently.

My SIL caught it back in March and according to the testing her antibody level was down to single digits last month, so almost gone. I did choose to sit next to her at a small gathering a few weeks ago though, I think we're going to be surprised at how long immunity lasts for most people.

Got it. Thanks

My co-workers grandson is a teenager,  he has had it twice. He had it at in April and he has it again now.  My youngest daughter is 24, she thought she may have had in April but never tested,  she took an anti body test about 3 months ago and tested positive for antibodies. She is just now recovering from covid-19.
