No, autoimmune diseases are NOT a contraindication to receiving the flu shot—in fact, vaccination is strongly recommended.
Patients with autoimmune diseases should receive annual influenza vaccination because they face increased risk of severe influenza complications, and the vaccine is both safe and effective in this population. 1, 2
Why Vaccination is Particularly Important
Patients with autoimmune inflammatory rheumatic diseases (AIRDs) have:
- Higher susceptibility to infections due to both their underlying disease and immunosuppressive treatments 3, 4
- Increased morbidity and mortality from influenza compared to the general population 2
- 13 times higher incidence of invasive pneumococcal infection (in SLE patients) compared to healthy individuals 2
Evidence for Safety and Effectiveness
The most recent and comprehensive evidence demonstrates:
Vaccination reduces respiratory morbidity and mortality: A large 2020 study of 30,788 AIRD patients showed influenza vaccination reduced risk of influenza-like illness (HR 0.70), hospitalization for pneumonia (HR 0.61), and death due to pneumonia (HR 0.56) 3
No disease exacerbation: Prospective controlled trials consistently show influenza vaccination does not increase disease activity in patients with SLE, RA, or other autoimmune conditions 5, 4
Adequate immune response: While immunogenicity may be somewhat reduced in patients on certain immunosuppressive medications (particularly rituximab, abatacept, or high-dose methotrexate), protective antibody levels are still achieved in the majority of patients 5, 6
Which Vaccine Type to Use
Inactivated influenza vaccine (IIV) is recommended for all patients with autoimmune diseases 7, 1:
Live attenuated influenza vaccine (LAIV) is contraindicated in immunocompromised patients, including those with autoimmune diseases on immunosuppressive therapy 1
The 2024-25 ACIP guidelines specifically list "children and adults who are immunocompromised due to any cause, including immunosuppression caused by medications" as a contraindication to LAIV 1
Optimizing Vaccine Response
To maximize effectiveness:
- Vaccinate early in the season (October-November) when possible 8
- Consider withholding methotrexate for 1-2 weeks post-vaccination to improve immunogenicity without significantly increasing disease flare risk 9
- Use high-dose or adjuvanted vaccines when available for enhanced immunogenicity in immunosuppressed patients 10
Common Pitfalls to Avoid
Don't confuse autoimmune disease with a contraindication: The only true contraindications are severe allergic reactions to vaccine components or previous doses 1
Don't use LAIV in immunosuppressed patients: Always use inactivated vaccines 1
Don't delay vaccination due to mild illness: Minor illnesses with or without fever are NOT contraindications 7, 11
Don't withhold vaccination due to fear of disease flare: Multiple studies confirm vaccination does not trigger autoimmune disease exacerbations 5, 4
The Bottom Line
The evidence overwhelmingly supports that benefits far outweigh any theoretical risks 3, 4. The 2019 EULAR recommendations, 2024 ACIP guidelines, and 2013 IDSA guidelines all strongly recommend annual influenza vaccination for patients with autoimmune diseases 1, 2, 5. Healthcare providers should actively promote seasonal influenza vaccination in this vulnerable population rather than viewing autoimmune disease as a reason to avoid it 3.
