Earlier this week, Germany shocked the public when it reduced the time a person is regarded to have natural immunity after being infected: from 6 months to just 2 months (parliamentarians exempt!) – even when most experts say the natural immunity lasts a year or even much longer.
With just a stroke of a pen, suddenly hundreds of thousands of previously infected Germans were deemed to no longer have natural immunity.
This contradicts recent findings by the Paul Ehrlich Institute, which found antibodies in previously infected people even after more than 430 days:
Antibodies Post-SARS-CoV-2 Infection – New Insights into the Sensitivity and Detection Duration of Antibody Tests
The Paul Ehrlich Institute, in cooperation with the University of Frankfurt am Main, examined the long-term antibody response after SARS-CoV-2 infection in 828 people with different degrees of COVID-19. The study measured binding antibodies against a range of SARS-CoV-2 target antigens, neutralising antibodies, and antibody binding strength (antibody avidity). Sensitivity, kinetics, and the duration of antibody detection depended on the detected antibody type, test design, target antigen of the anti-SARS-CoV-2 antibody test, antibody avidity, and COVID-19 severity.
The Journal of Clinical Virology reported on the results in its online edition from 4 December 2021.
The detection of virus-specific antibodies via antibody tests can assist in the diagnosis of both acute and previous SARS-CoV-2 (COVID-19) infections, whereby acute infections are known to occur with or without symptoms. SARS-CoV-2 antibody testing can identify individuals who have been previously infected with SARS-CoV-2, thus helping to determine the extent of SARS-CoV-2 infection amongst the population and to estimate the number of unrecorded infections.
However, SARS-CoV-2 antibody test results are difficult to interpret. First of all, because test results can vary greatly from person to person. In addition, SARS-CoV-2 antibody test results vary greatly in terms of methodology. It is also unclear how long specific antibodies are still detectable after an infection. Therefore, the use of antibody tests for SARS-CoV-2 requires an in-depth understanding of the variations in test sensitivity as well as the time dependence and duration of antibody detection. This was the subject of the present study.
The in vitro diagnostics (IVD) Testing Laboratory at the Paul Ehrlich Institute, headed by Dr Heinrich Scheiblauer, in cooperation with the University Hospital Frankfurt am Main, measured antibody responses over a period of more than 430 days after SARS-CoV-2 infection. 828 samples from 390 patients with different degrees of COVID-19 severity were examined using twelve different tests. These tests measured various antibody types (total antibodies, IgG, IgA, IgM), different SARS-CoV-2 target antigens (receptor binding domain (RBD), spike protein (S), and nucleoprotein (N)), neutralising antibodies, and the binding strength of antibodies to antigens (antibody avidity). Test specificity was determined on 676 pre-pandemic samples.
The results show that there is a distinct pattern to the sensitivity and detection duration of anti-SARS-CoV-2 antibody tests. This depended on the test design, the target antigen of the test, the antibody binding strength and the severity of COVID-19 in the period covered by the study. A characteristic feature amongst most patients was increasing antibody binding strength (antibody avidity) over time for the immunogenic SARS-CoV-2 antigens RBD and spike protein. These tests demonstrated high sensitivity and long detection times with increasing antibody avidity. Antibodies could be detected more than 430 days after infection without a foreseeable end point. Surrogate virus neutralisation tests, which were used to determine neutralising antibodies that inhibit the binding of RBD (which was also used in all currently authorised vaccines) to the ACE2 receptors, also showed a long detection duration of neutralising antibodies of over 430 days.
In comparison, RBD-based or spike-based antibody tests, which only detect the IgG, IgA, and IgM antibody types, showed lower baseline sensitivity and decreasing antibody titres over time, although IgG and IgA tests had maintained relatively high sensitivity (test positivity) up to 430 days.
In contrast, nucleoprotein-based tests showed a drop in antibody levels after just 120 days, which also led to a loss of sensitivity in the N-based IgG and IgM tests. This was shown to be related to a corresponding decrease in avidity for the non-immunogenic nucleoprotein.
With the exception of IgA antibody tests (96%), the specificity of the antibody tests was high for all tests at >99% and there was no cross-reactivity with endemic human coronaviruses.
This data can contribute to a more targeted application of antibody tests and to correct interpretations of SARS-CoV-2 antibody results in daily diagnostic work. In addition, it can help to determine the duration of potential immune protection against SARS-CoV-2.

Natural immunity as protective as vaccine induced immunity
It must be quite obvious by now that the aim of government bureaucracies is to get everyone vaccinated. There is absolutely no aim to cure people, or understand how this pandemic spreads – they have a simple single aim and will not waver. Even if one in two persons died 5 minutes after receiving it.
I have rarely met so single-minded a pursuit of a failed policy…
Just like climate change, wokeism, genderism, PC and much else the covid ‘pandemic’ is a political construct enacted for reasons we as ordinary people are not privy to. They are most certainly means to an end or to steps on the road to that end. But because we do not know what those aims that they are actually pursuing are we are left to rage impotently against obviously flawed, contradictory and down right stupid policies and make wild guesses as to what they intend. All of which is part of the ‘plan’ of course.
It will save a lot of money and inconvenience if everybody just dies now.

Thus showing, at a stroke, that this is NOT about medical science (verified observations and figures). NO! All this government blather about COVID is just a bureaucratically convenient method of controlling the populous.
Very similar things are happening in England for the same POLITICAL (not medical) reasons.

The large percentage of infections these days are Omicron infections.
Omicron is a new coronavirus common cold, not a Covid variant.
That’s why vaccines and antibodies from a prior Covid infection
have little or no effect to prevent Omicron infections.
Omicron has 30 mutations of the spike protein versus Delta Covid
A new Covid variant would have had just one or two.
Omicron has the same symptoms as a common cold.
A new Covid variant would have symptoms similar to Delta Covid,
which can be much more serious.
In plain English, a disease that has the sane symptom as
a common cold is a common cold. Omicron is a common cold.
Omicron may seem more dangerous than a common cold for two reasons:
(1) Omicron spreads so rapidly there will be more hospitalizations and deaths simply because of the huge quantity of infections. Common colds rarely cause hospitalizations or deaths, That’s true for Omicron too. But so many people get infected with Omicron so rapidly it seems to be more dangerous, and
(2) The PCR and other tests detect a virus, which could be Delta Covid, influenza, Omicron, any other coronavirus common cold virus and more than one dozen others. A person in a hospital claimed to have Omicron could actually have Delta Covis or influenza, both of which are more deadly than Omicron.
The hospitalization numbers are distorted because half the people in hospitals called Covid patients actually entered the hospital for something else and may not even have Covid symptoms, or they may have mild symptoms not noticed and far less important than the reason they are hospitalized. For NYC about half of Covid patients did NOT enter the hospital because of Covid. The hospital, however, makes extra money for each Covid patient, so they test everyone who comes in.
If Omicron keeps “crowding out” Delta Covid, this pandemic will
be over by Summer 2022, if not sooner. That’s my prediction on January 26, 2022. I rarely make predictions — this will probably be the only prediction I make this year.
Is there any testing being done to differentiate omicron from delta? Apparently not in the US. CDC uses modelling.
In Canada it is the vaccinated getting mass infected. Fully vaccinated employers are having trouble operating. The post office and medical clinics canot stay open. The ski industry cannot maintain operations.
There is no real proof that this is due to omicron.
Blatant doublespeak, it’s the shots which only last 2 months.
Seems there’s a problem.
Israel signs deal to procure 5 million Novavax COVID vaccine doses
‘Alternative’ non-mRNA coronavirus shot still subject to regulatory approval; shipment to arrive in coming months, with option for another 5 million shots.
Has anyone noticed how the “pandemic” has taken peoples’ minds off of CO2, and the warming the chicken littles want us to think it causes? Well, it seems they have found a way to make the gullible obsess over both at the same time.
Never underestimate the resourcefulness of pathological liars.
