Japanese researchers published a study warning of the risks associated with using blood from Covid vaccinated people for transfusions. They also claim that healthcare professionals must be made aware of these risks.
“ The health damage caused by genetic vaccinations is already extremely serious, and it is high time that countries and relevant organizations jointly take concrete steps to identify, control and eliminate the risks, ” said the scientists .
The study by Jun Ueda et al was published as a preprint entitled “ Concerns regarding Transfusions of Blood Products Derived from Genetic Vaccine Recipients and Proposals for Specific Measures.” specific measures) published.
The injections, which use a modified mRNA encoding the spike protein and lipid nanoparticles as the delivery system, have resulted in thrombosis and subsequent cardiovascular damage following vaccination. They have also been linked to a variety of diseases affecting all organs and systems, including the nervous system.
Based on these reports and the wealth of evidence that has come to light through their work, the researchers are alerting medical professionals to the various risks associated with blood transfusions using mRNA-contaminated blood.
They are now calling for the use of blood from people who have received Covid mRNA jabs to be suspended. But the problem doesn't just affect blood, as the scientists discovered.
The researchers warn medical professionals: "It should also be emphasized that the issues discussed here concern all organ transplants, including bone marrow transplants, and not just blood products."
Table 1 of the paper summarizes the six key concerns the researchers identified related to the use of blood products from Covid mRNA vaccine recipients.
1. Spike protein contamination
The spike protein, the antigen of the SARS-CoV-2 and the genetic vaccine, has already shown various toxic effects, including on red blood cells and platelet aggregation, amyloid formation and neurotoxicity, the researchers write in their paper.
It is important to know that the spike protein itself is toxic to humans. It has also been reported that the spike protein can cross the blood-brain barrier. Therefore, it is essential that the spike protein derived from the genetic vaccine be removed from the blood products.
2. Contamination with amyloid aggregates and microthrombi formed by spike proteins
It is not yet clear how the amyloid aggregates and microthrombi formed by the spike proteins develop into visible thrombi. However, once formed, amyloid aggregates may not be easily broken down and therefore must be removed from blood products.
3. Events due to weakened immune system of the donor and immune abnormalities due to immune imprinting or class switching to IgG4 etc. resulting from the administration of multiple genetic vaccines
If a donor's immune function is impaired by genetic vaccination, there is a risk that the donor has a (subclinical) infectious disease or is infected with a pathogenic virus and has developed viremia or other conditions, even if the donor has no subjective symptoms.
For this reason, healthcare professionals who perform surgical procedures, including blood collection and organ transplantation, and use blood products should handle the blood of genetic vaccine recipients with caution to prevent blood-borne infection.
Additionally, all healthcare professionals must be informed of these risks.
4. Lipid nanoparticles (“LNP”) and pseudouridinated mRNA (mRNA vaccines only)
In the case of mRNA vaccines, LNPs and pseudouridinated mRNA may remain in the blood of recipients if blood is drawn after genetic vaccination without sufficient delay.
LNPs are highly inflammatory and have been shown to be thrombogenic themselves, posing a risk to transfusion recipients. LNPs themselves have strong adjuvant activity and can trigger adjuvant-induced autoimmune syndrome (“ASIA syndrome”).
An additional risk is that if the pseudouridinated mRNA is absorbed into the recipient's blood while still packaged in LNPs, additional spike protein may be produced in the recipient's body.
5. Contamination with aggregated red blood cells or platelets
The spike protein causes red blood cells and platelets to aggregate, so these aggregates will enter the recipient's blood if they are not removed from the blood product.
6. Memory B cells producing IgG4 and IgG4 produced by them
Large amounts (serum concentration typically above 1.25-1.4 g/L) of non-inflammatory IgG4-positive plasma cells can cause chronic inflammation such as fibroinflammatory diseases.
IgG4 is an antibody and the acronym for immunoglobulin G4.
Earlier, the authors wrote that “long-term exposure to a specific identical antigen (in this case spike protein) causes immunoglobulins to become IgG4, and some of the B cells [or lymphocytes] that produce them are likely to differentiate into memory B cells that survive in the body for a longer period of time, so immune dysfunction in genetic vaccine recipients would be expected to last longer (Table 1, items 3 & 6). It is expected that more details on these points will emerge in the future.
The researchers also make suggestions for specific tests, testing methods and regulations to deal with these risks.
In their conclusion the authors write:
“The effects of these genetic vaccines on blood products and the actual harm they cause are currently unknown.
“Therefore, in order to avoid these risks and prevent further spread of blood contamination and aggravation of the situation, we strongly urge that the vaccination campaign with genetic vaccines be suspended and a benefit-harm assessment be carried out as early as possible.
“As we have repeatedly stated, the health damage caused by genetic vaccination is already extremely serious and it is high time that countries and relevant organizations jointly take concrete steps to identify the risks and control them and to eliminate.
Rumors that the Red Cross in the US sorts blood donations by vaccination status are false , according to reports . In Europe, too, there is no sign that the major blood donation organizations are making a distinction. However, there are private initiatives.
