Summary: The BNT162b2 vaccine induces transient activation of pDCs in SLE that enhances immune responses against SARS-CoV-2. Surprisingly, the vaccine also reduces circulating autoreactive T cells, suggesting a potential beneficial impact on SLE disease.

Surveillance of COVID-19 vaccine safety among elderly persons aged 65 years and older

Summary: This study evaluated the outcomes following COVID-19 vaccination in elderly persons and found a slight increase in the risk of pulmonary embolism, acute myocardial infarction, disseminated intravascular coagulation, and immune thrombocytopenia after receiving the BNT162b2 vaccine. However, after further evaluation, only the risk of pulmonary embolism still met the statistical threshold, while the risks of the other outcomes did not. More research is needed to determine the causal relationship between the vaccines and these outcomes.

Summary: This study aimed to evaluate the safety and immunogenicity of SCTV01C, a novel bivalent protein vaccine, as a booster for individuals who previously received two doses of mRNA vaccine. The results showed that SCTV01C vaccine had high cross-neutralizing antibody responses against Delta and Omicron variants, and was well-tolerated.

Class switch toward noninflammatory, spike-specific IgG4 antibodies after repeated SARS-CoV-2 mRNA vaccination

Pascal Irrgang et al.

Summary: RNA vaccines are effective in preventing SARS-CoV-2 infection, and high levels of neutralizing antibodies are crucial for vaccine-induced immunity. After the second mRNA vaccination, SARS-CoV-2-specific antibodies were increasingly composed of noninflammatory IgG4, which was further boosted by a third vaccination or breakthrough infections. This induction of IgG4 antibodies was not observed with adenoviral vectors. These findings have implications for the choice and timing of mRNA vaccine regimens, including booster shots.

COVID-19 Vaccination Did Not Increase the Risk of Potentially Related Serious Adverse Events: 18-Month Cohort Study in an Italian Province

Maria Elena Flacco et al.

Summary: This cohort study examined the incidence of potentially vaccine-related serious adverse events (PVR-SAEs) in the entire population of an Italian Province based on COVID-19 vaccination status. The findings showed that vaccinated individuals did not have an increased risk of death or PVR-SAEs compared to the unvaccinated. These results were consistent across different demographics, vaccine types, and infection statuses. Further research is needed to assess the long-term safety of COVID-19 vaccines.

Intervening early with anti-inflammatory drugs, especially NSAIDs, in the outpatient setting could prevent disease progression and long-term complications. Observational studies have shown promising results regarding the use of NSAIDs for early outpatient treatment of COVID-19.

Summary: SARS CoV-2 enters host cells by binding to ACE2 through its Spike protein, and COVID-19 mRNA vaccines produce Spike protein that follows the same route. Patients with myocardial injury from COVID-19 or mRNA vaccination showed similar gene expression changes associated with inflammation, coagulopathy, and myocardial dysfunction.

Summary: This study investigated a patient who developed persistent skin lesions for over 3 months following vaccination with mRNA COVID-19 vaccines. The results showed that the lesions were caused by VZV infection, and the vaccine-encoded spike protein was found in the affected skin. The discussion suggested that mRNA COVID-19 vaccines may induce persistent VZV reactivation by disrupting the immune system. Further investigation into the role of spike protein is needed.

Immune imprinting, breadth of variant recognition, and germinal center response in human SARS-CoV-2 infection and vaccination

Katharina Roltgen et al.

Summary: During the SARS-CoV-2 pandemic, different vaccines have been used globally. This study compares the antibodies generated by mRNA vaccines, infection, and other types of vaccines. It shows that mRNA vaccines result in a better antibody breadth against viral variants compared to infection. Infection leads to variant-specific antibodies, while mRNA vaccination imprints responses towards the original virus strain. mRNA vaccines also stimulate robust germinal centers in lymph nodes, enhancing the immune response.

Summary: Male patients aged 12-17 have an increased risk of myo/pericarditis after mRNA vaccination. A risk-benefit analysis shows that two-dose vaccination is beneficial only for nonimmune girls with comorbidities, while even one dose carries more risk than benefit for boys with prior infection and no comorbidities. In the context of the omicron variant, one dose may provide protection for nonimmune children, but the second dose does not appear to offer additional benefits at a population level.

The spike protein of SARS-CoV-2 induces endothelial inflammation through integrin α5β1 and NF-κB signaling

Summary: COVID-19 causes dysfunction of vascular endothelial cells, leading to edema, vascular inflammation, and coagulation. This study reveals that the spike protein of SARS-CoV-2 activates the inflammatory response in endothelial cells through binding with integrin alpha 5 beta 1, resulting in the expression of inflammatory and coagulation factors, as well as increased vascular permeability and leukocyte adhesion. These findings highlight integrin alpha 5 beta 1 as a potential target for treating vascular inflammation in COVID-19.

The findings suggest that vaccine effectiveness decreases over time, but the rate of waning varies by vaccine type. The effectiveness in preventing severe COVID-19 seems to be better maintained. The results provide support for administering a third vaccine dose as a booster.

Could SARS-CoV-2 Spike Protein Be Responsible for Long-COVID Syndrome?

Summary: SARS-CoV-2 infects cells through its spike protein binding to the surface receptor, resulting in acute symptoms known as COVID-19. Increasing evidence suggests the development of a chronic condition called long-COVID, characterized by fatigue and neuropsychiatric symptoms. Studies have found that the spike protein may have neurotoxic effects, causing perivascular inflammation and neuro-inflammation, contributing to long-COVID symptoms.

SARS-CoV-2 mRNA Vaccination and Graves' Disease: A Report of 12 Cases and Review of the Literature

The majority of the patients were female and most were able to receive the second dose of the vaccine without exacerbating their condition. Additionally, 21 other similar cases were reported internationally. The study suggests that clinicians should be vigilant of autoimmune thyroid disorders being precipitated or exacerbated in predisposed individuals after exposure to the SARS-CoV-2 vaccination. Further epidemiological and mechanistic studies are needed to understand the possible associations between SARS-CoV-2 vaccines and the development of thyroid autoimmunity.

Additionally, the damage to cardiomyocytes caused by spike proteins is enhanced when angiotensin II is added, resulting in potential cardiac dysfunction.

Adverse effects of COVID-19 vaccines and measures to prevent them

Kenji Yamamoto

Summary: A recent study published in The Lancet suggests that immune function among individuals who received two doses of COVID-19 vaccine becomes lower after 8 months compared to those who were unvaccinated. Therefore, frequent booster shots may not be feasible according to recommendations from the European Medicines Agency. The decrease in immunity could be caused by various factors and could explain the association found between COVID-19 vaccination and shingles. It is important to discontinue further booster vaccinations as a safety measure and to record the date of vaccination for patients' medical records.

Summary: This report presents a case of a 76-year-old man with Parkinson's disease who died three weeks after receiving his third COVID-19 vaccination. Post-mortem examinations confirmed Parkinson's disease and revealed signs of aspiration pneumonia and systemic arteriosclerosis. Histopathological analyses showed acute vasculitis and multifocal necrotizing encephalitis in the brain, as well as chronic cardiomyopathy and myocarditis in the heart. Immunohistochemistry testing detected only spike protein in the inflammation foci of the brain and the heart, suggesting the presence of spike protein is due to vaccination rather than viral infection.
