Antibodies persisting doesn't mean immunity and the levels of antibodies vary too much from person to person.

Having antibodies for 12 months still might mean you're only immune for 6 months and that can vary from one to six months or from one to 12 months which winds up not being useful enough information to build policy around.

Maybe I should ask what level of accuracy you think has been used to build public policy up until now. I mean, the current public policy is to recommend the bivalent booster to everyone over the age of 5 that is at least 2 months out from their last vax.

What level of information you think was used in making that recommendation? I seriously doubt they have accurate information and modeling showing antibody levels and corresponding immunity over a 12-month period for a large population.

Damn. I must be super unlucky. I've had it four times now. Twice in the last 4 months. The last time it was just a few annoying cold-like symptoms, so less intense for sure.

Read up on T-cell exhaustion.

[deleted] t1_j03gbpe wrote

Describes a condition in which T cells (a type of immune cell) lose their ability to kill certain cells, such as cancer cells or cells infected with a virus. This can happen when cancer, chronic infection, or other conditions cause the body’s immune system to stay active for a long time. Exhausted T cells have high amounts of immune checkpoint proteins on their surface, which may keep the activity of the T cells suppressed. In cancer treatment, drugs that target these proteins may be given to allow the T cells to better kill cancer cells. Learning more about T-cell exhaustion may help in the development of new types of immunotherapy to treat cancer.

Okay, so I'm a hypochondriac already. Are you telling me I have cancer now???!!!

No, but covid may make your more susceptable to it, and any subsequent infections. Funguses, bacteria, viruses... Including other strains of covid.

It may mostly resolve in a few months. Protect yourself.

And then get cd4 and cd8 counts checked

My bloodwork always comes up with a few things out of normal range, but my doctors always say that when not combined with other skewed results it's not anything to worry about. If I get this checked, it will probably be off but they will tell me it's nothing to worry about. I'll then continue to be a hypochondriac and look up every type of cancer I probably have.

I am praying for you

I'm not a religious person, but I think I do need some prayers. Especially this week. I'm usually the most optimistic person anyone knows but on the inside I'm crumbling and am in shambles. I exersize daily to run away from my troubles. Thanks for your prayers. I think all broken people could use a little something. Anything. Thanks again.

Didnt for me. Had Covid in May and then again in August. And i had already had 3 shots by May

Antibodies could persist, but it doesn't mean you wouldn't get infected again.

Probably had two different strains. Different enough to evade previous immunity.

Sounds about right. A room mate has had it three times now, and it was a different strain each team. Alpha, Delta, and Omicron in the beginning of November.

I've never had a positive test or any of the classic symptoms, but round about January of last year I had a week of weird leg cramps, and my antibody levels reached Reactive + at my platelet donation, giving me a good indication that I fought off a systematic infection without it touching my respiratory system (where it would be detected by a nasal swab.)

I got the new bivalent booster in November then promptly got Covid 2 weeks later for the first time…. This thing mutates like crazy

I got the latest booster mid-October in preparation for vacation.

Stupid me got on an airplane end of Oct and promptly got Covid. I was mildly sick for two weeks and had secondary symptoms (shortness of breath, vertigo, diarrhea) for another two.

> Abstract

> Objective:

>To evaluate dynamics of antibody levels following exposure to SARS-CoV-2 during 12 months in Dutch non-vaccinated hairdressers and hospitality staff. > > Methods:

>In this prospective cohort study, blood samples were collected every three months for one year, and analyzed using a qualitative total antibody ELISA and a quantitative IgG antibody ELISA. Participants filled out questionnaires, providing information on demographics, health and work. Differences in antibody levels were evaluated using Mann-Whitney U and Wilcoxon Signed Rank tests. Beta coefficients (B) and 95% confidence intervals (95%CI) were calculated using linear regression. > > Results:

>Ninety-five of 497 participants (19.1%) had ≥1 seropositive measurement before their last visit using the qualitative ELISA. Only 2.1% (2/95) seroreverted during follow-up. Of the 95 participants, 82 (86.3%) tested IgG seropositive in the quantitative ELISA too. IgG antibody levels significantly decreased in the first months (p<0.01), but remained detectable up to 12 months in all participants. Higher age (B, 10-years increment: 24.6, 95%CI: 5.7-43.5) and higher BMI (B, 5kg/m² increment: 40.0, 95%CI: 2.9-77.2) were significantly associated with a higher peak of antibody levels. > > Conclusions:

>In this cohort, SARS-CoV-2 antibodies persisted for up to one year after initial seropositivity, suggesting long-term natural immunity.
