[Autoimmune connective tissue diseases and vaccination]

Area of Science:

• Immunology
• Rheumatology
• Epidemiology

Background:

• The potential link between infectious agents, vaccinations, and autoimmune diseases is a long-standing topic.
• Increased autoimmune disease incidence and widespread childhood vaccinations raise questions about vaccine safety.
• Case reports and media discussions often link vaccination to autoimmune events, necessitating evidence-based evaluation.

Purpose of the Study:

• To explore potential mechanisms connecting infections, vaccinations, and autoimmunity.
• To review case reports of autoimmune diseases temporally associated with vaccination.
• To analyze findings from case-nested studies on vaccination and autoimmunity.

Main Methods:

• Literature review of case reports, focusing on systemic connective tissue diseases.
• Analysis of case-nested studies investigating vaccination and autoimmune disease links.
• Evidence-based medicine approach to assess vaccination safety.

Main Results:

• Currently, no conclusive evidence establishes a causal relationship between vaccination and autoimmune diseases.
• The sensitivity of existing studies to detect a potential link remains a question.
• The debate on vaccination safety and autoimmunity is ongoing, requiring more data.

Conclusions:

• Prophylactic vaccination is crucial for patients with autoimmune rheumatic diseases.
• The notion that vaccines are contraindicated in this population is a myth that needs to be dispelled.
• Continued research is necessary to fully understand autoimmunity pathogenesis.
