From the Guidelines

You can still receive the Tdap vaccine if you are allergic to Tetanus Immunoglobulin, as the two are fundamentally different substances. The Tdap vaccine contains inactivated toxins (toxoids) from the bacteria that cause tetanus, diphtheria, and pertussis, whereas Tetanus Immunoglobulin is a blood product containing antibodies against tetanus 1. However, it is crucial to inform your healthcare provider about any allergies before receiving the vaccine, as they may recommend additional monitoring after vaccination as a precaution. According to the recommendations of the Advisory Committee on Immunization Practices (ACIP), a severe allergic reaction to a previous dose of any tetanus-containing vaccine is a contraindication to receiving Tdap 1. Key points to consider include:

  • Informing your healthcare provider about any allergies before receiving the vaccine
  • The difference between Tetanus Immunoglobulin and the Tdap vaccine
  • The importance of the Tdap vaccine in preventing serious diseases
  • The recommendation for adults to receive the Tdap vaccine every 10 years, with one dose replaced by Tdap if they haven't received it previously. It's essential to weigh the benefits and risks of vaccination, and your healthcare provider can help make an informed decision based on your specific situation 1.

From the Research

Allergy to Tetanus Immunoglobulin and Tdap Vaccine

  • The Tdap vaccine is a combination vaccine that protects against Tetanus, Diphtheria, and Pertussis.
  • If an individual is allergic to Tetanus Immunoglobulin, it is essential to assess the risk of receiving the Tdap vaccine.
  • According to the study 2, immediate allergy to tetanus toxoid vaccine is rare, with an incidence of anaphylactic responses of 0.001%.
  • The study 2 also found that patients allergic to TT vaccine produced IgE and IgG antibodies, which decreased at different rates but remained for at least 5 years.

Safety of Tdap Vaccine in Individuals with Allergy to Tetanus Immunoglobulin

  • There is no direct evidence in the provided studies that specifically addresses the safety of administering the Tdap vaccine to individuals with an allergy to Tetanus Immunoglobulin.
  • However, the studies 3, 4, 5, and 6 demonstrate the safety and immunogenicity of the Tdap vaccine in various populations, including adults and healthcare personnel.
  • These studies suggest that the Tdap vaccine is generally well-tolerated and effective in preventing pertussis, but they do not provide specific guidance on its use in individuals with an allergy to Tetanus Immunoglobulin.

Considerations for Vaccination

  • Individuals with an allergy to Tetanus Immunoglobulin should consult their healthcare provider to discuss the risks and benefits of receiving the Tdap vaccine.
  • The healthcare provider may recommend alternative vaccination strategies or precautions to minimize the risk of an allergic reaction.
  • Further research is needed to determine the safety and efficacy of the Tdap vaccine in individuals with an allergy to Tetanus Immunoglobulin, as the current evidence is limited 2, 3, 4, 5, 6.
