Blood Clots & Fibrous Clots

• COVID-19 Vaccines: A Risk Factor for Cerebral Thrombotic Syndromes
  https://www.preprints.org/manuscript/202406.1236/v1
  (Study compares the rates of cerebral thrombosis among COVID-19 vaccine recipients to the large number of individuals who take an influenza vaccine annually. Compared to influenza vaccines given over 34 years, COVID-19 vaccines in 36 months of use had over 1000-fold increased risk of most blood clot events, and compared to all vaccines combined administered over 34 years, this risk remained at over 200-times greater with COVID-19 vaccination.

  (“in 72% of cases, no other cause for SVT could be identified following SARS-CoV-2 vaccination. These cases were different from patients with nonvaccine–related SVT, with lower incidence of prothrombotic conditions, higher rates of bowel ischemia, and poorer outcome.” Explanatory article here.)

• Sialylated Glycan Bindings from SARS-CoV-2 Spike Protein to Blood and Endothelial Cells Govern the Severe Morbidities of COVID-19

  (Spike protein causes the clumping of blood cells, whether by infection or vaccine injection. Explanatory video here.)

• Safety Profiles of mRNA COVID-19 Vaccines Using World Health Organization Global Scale Database (VigiBase): A Latent Class Analysis
  https://link.springer.com/article/10.1007/s40121-022-00742-5
  ("We found five distinguished clusters of serious AEs following mRNA COVID-19 vaccination, with a high proportion of vascular disorders, including pulmonary embolism, deep vein thrombosis, and thrombosis, along with respiratory disorders. Mainly, the number of COVID-19 vaccines administered due to the pandemic resulted in a massive number of AEs following COVID-19 vaccination.")

• Adverse events following COVID-19 mRNA vaccines: A systematic review of cardiovascular complication, thrombosis, and thrombocytopenia
  https://onlinelibrary.wiley.com/doi/10.1002/iid3.807
  (“Cardiovascular (CV) events such as thrombosis [most common], thrombocytopenia, stroke [most common after Moderna], and myocarditis frequently occur with the mRNA vaccines studied. A significant number of studies included in our review reported BNT162b2 events, which presses the need to conduct more research into the CV implications of mRNA-1273 (Moderna) vaccine.” Keep in mind usually <50 deaths with a widely used, novel product prompts a worldwide recall. To have 284 well described deaths in one year as a result of cardiovascular and or thrombotic complications is a striking finding in the medical literature for products that are still on the market and promoted by public health agencies all over the world. Explanatory article here.)

• Thrombosis Development After mRNA COVID-19 Vaccine Administration: A Case Series

  (“Thrombosis associated with mRNA-derived vaccines is not yet recognized as a separate entity by formal societies. As a result, no clear guidelines or expert opinions exist on the ideal management.”)

• Thromboembolic Events after COVID-19 Vaccination: An Italian Retrospective Real-World Safety Study
  https://www.mdpi.com/2076-393X/11/10/1575
  (Both Pfizer and Moderna cause blood clots at similar rates, although Moderna causes more pulmonary emboli and Pfizer more leg clots. For Pfizer & Moderna, women account for 70% of blood clots. Moderna had 7.1 thromboembolic events per 100,000 doses, Pfizer 7.6 per 100,000. [J&J and AstraZeneca were 5-6x that amount.] “We may have underestimated rates of thrombotic adverse events”)

• Incidence and outcomes of splanchnic vein thrombosis after diagnosis of COVID-19 or COVID-19 vaccination: a systematic review and meta-analysis
  https://link.springer.com/article/10.1007/s11239-022-02732-3
  (Because the Spike protein on the surface of SARS-CoV-2 causes blood clotting, most venous thromboembolic syndromes are seen in both COVID-19 patients and those who took the vaccines. It is likely that the highest risk patients are those who have cumulatively been exposed to the Spike protein via multiple injections and one or more occurrences of COVID-19 illness. Explanatory article here.)

• Factors associated with stroke after COVID-19 vaccination: a statewide analysis
  https://www.frontiersin.org/journals/neurology/articles/10.3389/fneur.2023.1199745/full
  (A statewide study that followed 5 million people living in Georgia found that those who contracted COVID-19 within 21 days of vaccination were at the highest risk of stroke.)
