Concerns | Description | References | |
---|---|---|---|
1 | Spike protein contamination | The spike protein, which is the antigen of SARS-CoV-2 and genetic vaccines, has already been found to have various toxicities, including effects on red blood cells and platelet aggregation, amyloid formation, and neurotoxicity. It is essential to recognize 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 to remove the spike protein derived from the gene vaccine itself from blood products. | [22,29,55,56,57,58,59,60] |
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 readily cleared and therefore need to be removed from blood products. These amyloid aggregates have also been shown to be toxic. | [51,52,98] |
3 | Events attributable to decreased donor immune system and immune abnormalities due to immune imprinting or class switch to IgG4, etc. resulting from multiple doses of genetic vaccines | When the immune function of a donor is impaired by gene vaccination, there is a risk that the donor has some (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 sampling and organ transplantation, as well as using blood products, should manage the blood of genetic vaccine recipients with care to prevent infection through blood. It will also be necessary to inform all healthcare professionals of these risks. | [63,64,65,68,69,70,71,76,77,78,79,80,82,83,84,85,86,87] |
4 | Lipid nanoparticles (LNPs) 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 collected without a sufficient deferral period after gene vaccination. LNPs are highly inflammatory and have been found to be thrombogenic themselves, posing a risk to transfusion recipients. LNPs itself has potent adjuvant activity and is at risk of inducing Adjuvant-Induced Autoimmune Syndrome (ASIA syndrome). An additional risk is that if the pseudouridinated mRNA is incorporated into the recipient’s blood while still packaged in LNPs, additional spike protein may be produced in the recipient’s body. | [23,40,44,99,100,101,102,103,104,105] |
5 | Contamination with aggregated red blood cells or platelets | The spike protein causes red blood cells and platelets to aggregate and therefore these aggregates will be carried into the recipient’s blood unless they are removed from the blood product. | [7,8,9,10,11,49] |
6 | Memory B cells producing IgG4 and IgG4 produced from 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 disease. | [73,74,75,106,107] |

1 | Spike protein content in blood | Immunochemical techniques include enzyme-linked immunosorbent assay, immunophenotyping, mass spectrometry, liquid biopsy, and a combination of liquid biopsy and proteomics. First, we propose mass spectrometry that can directly measure the protein itself. | [28,29,122,123,124,125,126] |
2 | Spike protein mRNA | PCR and/or liquid biopsy are the options. If mRNA for the spike protein is detected, LNPs may be present (mRNA vaccines only). | [124,127,128] |
3 | Spike protein DNA | PCR and liquid biopsy are the options. This test is necessary because AstraZeneca’s viral vector is a DNA vaccine. For mRNA vaccines, it is believed that pseudouridinated mRNA is not reverse transcribed, but this test is required if the spike protein remains for a prolonged period. | [124,128] |
4 | Markers associated with autoimmune disorders | Long-term persistence of the spike protein in the blood increases the risk of autoimmune disease. Therefore, it would be useful to test for autoimmune disease using antinuclear antibodies as biomarkers in people who are positive for the spike protein, taking into account the results of interviews regarding the subjective symptoms. | [27,105,129,130] |
5 | Interview | A history of genetic vaccination and COVID-19, current and previous medical history, and subjective symptoms (e.g. headache, chest pain, shortness of breath, malaise) should be obtained from blood donors and formally recorded. The types of questions included in the interview are critical to facilitate diagnosis and treatment of COVID-19 PVS, as more people are complaining of psychiatric and neurological symptoms after genetic vaccination. | [15,131,132] |
6 | Proteins resulting from frameshifting of pseudouridinated mRNA | Although it is not yet clear whether proteins other than the spike protein are translated from pseudouridinated mRNAs, mass spectrometry may be useful in confirming this. | [133] |
7 | Components of amyloid aggregates and thrombi | Common markers of thrombosis, such as D-dimer, are used first. Once the major components of amyloid aggregates and thrombi have been identified, their use as biomarkers is proposed. Understanding the composition of amyloid aggregates will be important in the future, as amyloid aggregates have been reported to be toxic. Understanding the composition of amyloid aggregates may provide clues to how amyloid is broken down. | [51,52,98,134] |
8 | Components of SARS-CoV-2 other than the spike protein gene | This test will help determine whether the spike protein is from the genetic vaccine or from SARS-CoV-2. Potential candidates include nucleocapsid. | [4,5,41,128] |
9 | Immunoglobulin subclasses | It may be necessary to analyze immunoglobulin subclasses (the amount of IgG4) if immunosuppression from multiple doses of the genetic vaccine is a concern. | [68,69,70,71] |
10 | Anti-nucleocapsid antibodies | The presence or absence and amount of anti-nucleocapsid antibodies as well as antibody isotypes may be an indicator(s) in distinguishing whether genetic vaccination or long COVID is the cause. | [135,136,137] |
11 | Other | Myocarditis and pericarditis after genetic vaccination have been reported in various countries. Therefore, those with subjective symptoms may also be tested for myocarditis marker, such as cardiac troponin T. | [18,19,29,138,139,140] |
