SARS-CoV-2 immunity persists for up to 11 months after natural infection

In the current study, the researchers followed 228 convalescence plasma donors between April and February 2021. They were assessed for levels of neutralizing antibodies and the total and immunoglobulin G (IgG)-specific S protein antibodies using a lab-developed fluorescent reduction neutralization assay (FRNA) and the VITROS anti-SARS-CoV-2 Total.

The team analyzed the data to determine the link between antibody levels and clinical characteristics, presenting a comprehensive view of SARS-CoV-2 antibody changes over 11 months after being infected with SARS-CoV-2. The purpose of the study was to better understand COVID-19 responses in individuals who obtained the virus in the community.

Before August 2020, the U.S. Food and Drug Administration recommended titers of at least 1:160 for investigational convalescent plasma, but a titer of 1:80 was accepted if higher-titer units were not available.

The study findings revealed that 97 percent of COVID-19 convalescent donors had anti-SARS-CoV-2 antibodies at baseline testing.

In the follow-up visits, 91.4 percent of the 116 donors presenting for repeat timepoints had detectable neutralizing levels up to 11 months after the onset of symptoms. In comparison, 63 percent had detectable neutralizing titers. However, about 25 percent of the donors drop titers of neutralizing levels until these become undetectable over time.

Further, the study showed that most CCP plasma donors, regardless of COVID-19 disease severity, develop antibodies to SARS-CoV-2, and more than 70 percent have neutralizing antibodies.

This means that the body generates sustained immunological memory for most of the first year following SARS-CoV-2 infection, even in mild COVID-19 cases. However, some people may experience a decline in the immunological response against SARS-CoV-2 over the first months following symptom resolution, especially in those who had an asymptomatic or mild illness.

If you had the CCP-1984 virus you acquired antibodies to the entire virus, not just the little fragment(s) contained by the vaccine.

Surviving the CCP-1984 virus would give you superior immunity compared to the CCP-1984 vaccine.

I assume a systemic infection confers longer immunity than a vaccination.

I would think so, but I’m no scientist. I know I’m not getting the vaccine. I had the virus.

Even if your body doesn’t have the Covid-19 anti-bodies running around your body, doesn’t mean your body forgets how to make them. People who had SARS-1 were immune to Covid-19/SARS-2 seventeen years later.

I like your name for the virus. I want a t shirt that reads “I survived the CCP-1984 Virus. “

“Even if your body doesn’t have the Covid-19 anti-bodies running around your body, doesn’t mean your body forgets how to make them. “

Exactly right. Your bone marrow can crank out those antibodies at a moments notice.

I expect a lifetime of immunity from one infection. It is still the way of biology. Those who get a second or third infection are the outliers, the one percenters.

Suspected early on. Some folks are already immune to this according to a study published in FraudXi’s NIH docs:

I read elsewhere that recovery imparts lifetime immunity. So, which one is lying?

I don’t see how anyone could predict lifetime immunity at this point; the virus hasn’t been around long enough for anyone to know that. The studies will be ongoing for years - this one shows that while titers decline somewhat in most participants, the level remains reasonable to predict immunity at 11 months.

I’ll take Lifetime Immunity for $1000

I got the fauci flu on 1/25/20 before it was fashionable and got a weak head cold for 2 days, first time sick with anything in around 30 years or so

“the fauci flu”

That is the first time I have seen it called that! Excellent! Jericho Green calls it the sweet n sour sniffles, but since it is severe for some people, that may a bit too far.

Exactly, it is like the entire world has forgotten how the human immune system works.

Based on the record of similar viruses, I assume.

I just tested positive for antibodies so apparently I had COVID but never knew it (no symptoms). A liberal friend told me I should still get the vaccine because he does not trust the science of antibodies. LMAO!

No way that anything is better than antibodies acquired via infection. Got that straight from a medical researcher, and it’s also just common sense.
