From Immunization to Autoimmunity: A Deep Dive Into Post-COVID-19 Vaccine Reactions-A Narrative Review

Area of Science:

• Immunology
• Vaccinology
• Autoimmunology

Background:

• COVID-19 vaccines have been crucial in controlling the pandemic.
• Rare autoimmune adverse events post-vaccination require careful consideration.
• Understanding these events is vital for healthcare providers.

Purpose of the Study:

• To review current evidence on autoimmune events after COVID-19 vaccination.
• To explore potential immunological mechanisms.
• To inform diagnosis and patient management.

Main Methods:

• Comprehensive literature search of PubMed, Scopus, and Google Scholar.
• Prioritized studies on mechanisms, manifestations, and management.
• Qualitative synthesis of diverse study types (case reports, cohort studies).

Main Results:

• Increasing reports of COVID-19 vaccine-associated autoimmune events noted.
• Examples include vaccine-induced immune thrombotic thrombocytopenia (VITT), Guillain-Barré syndrome (GBS), Graves' disease (GD), and autoimmune hepatitis (AH).
• Clinical manifestations, risk factors, and management strategies were reported.

Conclusions:

• Autoimmune reactions to COVID-19 vaccines are rare but significant.
• Personalized risk assessment and management are essential.
• Future research should focus on risk factors and mechanistic pathways, potentially using AI-driven predictive biomarkers.
