The S1 protein of SARS-CoV-2 crosses the blood–brain barrier in mice

(While this is a problem both for natural spike as well as vaccine-induced spike, it is a more serious problem for vaccine-induced spike, because natural spike clears from the body in days in most cases, whereas mRNA-infected cells can continue to produce spike for months, or even longer with repeated booster shots.)

Immune imprinting, breadth of variant recognition, and germinal center response in human SARS-CoV-2 infection and vaccinationhttps://www.cell.com/cell/fulltext/S0092-8674(22)00076-9
(Vaccine spike antigen and mRNA persist for at least two months in lymph nodes—which was as long as the study looked for them. Protein production of spike is higher than those of severely ill COVID-19 patients. Vaccinated people infected with variants of Sars-Cov-2 produce antibodies biased toward the original and now extinct variant rather than the one that has actually infected them.)

Previous COVID-19 infection but not Long-COVID is associated with increased adverse events following BNT162b2/Pfizer vaccination

(This research suggests that serious side effects from these vaccines are more common in those who already possess natural immunity.)

On COVID vaccines: why they cannot work, and irrefutable evidence of their causative role in deaths after vaccination

(Pathology results show that 93% of people who died after being vaccinated were killed by the vaccine. Explanatory video here.)

("Since translation of the mRNA occurs potentially and—most importantly—unpredictably in any tissues and organs, and it can be easily hypothesized that inappropriate production in vulnerable tissues may represent a major risk factor for local tissue damage, leading to myocarditis, central and peripheral neuropathies, vasculopathies, myopathies, endocrinopathies and other disease, depending on the location and amount of S protein expression.”)

Inability to work following COVID-19 vaccination–a relevant aspect for future booster vaccinations

("Among 1704 health care workers enrolled, 595 (35%) were on sick leave following at least one COVID-19 vaccination, leading to a total number of 1550 sick days. Both the absolute sick days and the rate of health care workers on sick leave significantly increased with each subsequent vaccination. There is a risk of additional staff shortages due to post-vaccination inability to work, which could negatively impact the already strained healthcare system and jeopardise patient care.")

The anti-SARS-CoV-2 BNT162b2 vaccine suppresses mithramycin-induced erythroid differentiation and expression of embryo-fetal globin genes in human erythroleukemia K562 cells

(Increasing doses of Pfizer mRNA vaccine cause dramatic suppression of globulin gene expression in bone marrow stem cells. Also: “searching for circulating Spike in plasma might help in understanding unexpected adverse effects following COVID-19 mRNA vaccination." Conclusion: “SARS-CoV-2 S-protein, COVID-19 mRNA vaccines and SARS-CoV-2 infection might have dramatic effects on the hematopoietic [blood cell production] compartment.” )

US COVID-19 Vaccines Proven to Cause More Harm than Good Based on Pivotal Clinical Trial Data Analyzed Using the Proper Scientific Endpoint, “All Cause Severe Morbidity”https://www.scivisionpub.com/pdfs/us-covid19-vaccines-proven-to-cause-more-harm-than-good-based-on-pivotal-clinical-trial-data-analyzed-using-the-proper-scientific--1811.pdf
(Paper analyzed the clinical trial data for all three US vaccines and confirmed the lack of any overall benefit. There was an increase in morbidity which was highly statistically significant in all three vaccines. It concluded, “Based on this data it is all but a certainty that mass COVID-19 immunization is hurting the health of the population in general. Scientific principles dictate that the mass immunization with COVID-19 vaccines must be halted immediately because we face a looming vaccine induced public health catastrophe.”)

Brief research report: impact of vaccination on antibody responses and mortality from severe COVID-19
https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2024.1325243/full
(Ohio State University researchers published a stunning finding. Vaccinated Covid patients hospitalized with respiratory failure were more likely to die than the unjabbed: 70% died, compared to 37%.)

Long-term adverse events of three COVID-19 vaccines as reported by vaccinated physicians and dentists, a study from Jordan and Saudi Arabia

(Study followed 498 vaccinated physicians and dentists showed that around 6 percent reported long-term fatigue post-vaccination.)
