Administering Flu Shot with Steroids in Asthma Patients

Yes, it is safe and recommended to administer the flu shot on the same day as steroid treatment in patients with asthma. 1

Safety and Efficacy Considerations

  • Influenza vaccination is specifically recommended for patients with asthma because they are at high risk for influenza-associated complications 1
  • Annual influenza vaccination is considered a preventative measure for all patients with asthma 2
  • The immune response to influenza vaccine in asthmatic patients receiving corticosteroids is comparable to healthy subjects 3
  • Studies have demonstrated that influenza vaccination does not trigger asthma exacerbations in patients with asthma 4

Corticosteroid Use and Vaccination Guidelines

  • For patients with asthma taking the equivalent of prednisone ≥20 mg daily, administering influenza vaccination is conditionally recommended 1
  • For patients taking lower doses of corticosteroids, there is no recommendation to delay influenza vaccination 1
  • The immune response to the A antigens of the inactivated influenza vaccine in subjects with asthma is not adversely affected by inhaled corticosteroid therapy 2
  • While high-dose inhaled corticosteroid therapy may slightly diminish the response to the B antigen of the vaccine, the overall protective effect remains sufficient 2

Type of Vaccine Considerations

  • Inactivated influenza vaccine (flu shot) is appropriate for patients with asthma on corticosteroids 1
  • Live attenuated influenza vaccine (nasal spray) should NOT be used in patients with asthma or those receiving immunosuppressive therapies 1
  • The Advisory Committee on Immunization Practices (ACIP) specifically lists asthma as a contraindication for live attenuated influenza vaccine 1

Timing Considerations

  • There is no need to time the influenza vaccination in relation to steroid administration for patients with asthma 1
  • Vaccination can be administered during routine visits beginning in September and throughout the influenza season 1
  • The optimal time for organized vaccination campaigns is usually from October through mid-November 1

Clinical Evidence

  • A study of 294 asthma patients showed that corticosteroid therapy did not significantly impair the immune response to influenza vaccination 2
  • Research has confirmed that influenza vaccination in asthmatic patients with inhaled corticosteroids achieved protective antibody levels comparable to healthy subjects 3
  • A double-blind study of 318 adult patients with chronic asthma found no difference in peak expiratory flow rate or clinical symptoms between those receiving active vaccine versus placebo, regardless of steroid use 4

Common Pitfalls to Avoid

  • Do not withhold influenza vaccination from asthma patients due to unfounded concerns about exacerbations - studies have shown vaccination is safe in this population 5, 4
  • Do not administer live attenuated influenza vaccine (nasal spray) to patients with asthma - use only the inactivated influenza vaccine (injection) 1
  • Do not assume that corticosteroid therapy will completely negate the benefits of vaccination - evidence shows adequate immune response even with corticosteroid treatment 2, 3

In conclusion, influenza vaccination should be administered to asthma patients regardless of same-day steroid treatment, as the benefits of protection against influenza-related complications outweigh any theoretical concerns about diminished vaccine response.
