From the Guidelines

If you are allergic to the influenza vaccine, you may still be able to receive meningococcal vaccines (MenACWY or MenB), but you should consult with your healthcare provider first. The allergic reactions to flu vaccines are typically related to specific components like egg proteins, preservatives, or stabilizers that may not be present in meningococcal vaccines 1. These vaccines have different manufacturing processes and ingredients. Your healthcare provider will need to determine what specific component of the flu vaccine caused your allergic reaction and whether that component is also present in meningococcal vaccines. They may recommend skin testing before vaccination or administer the vaccine in a controlled medical setting where any potential allergic reactions can be immediately treated. Some key points to consider when deciding to receive the meningococcal vaccine if allergic to the flu vaccine include:

  • The severity and nature of the previous allergic reaction to the flu vaccine
  • The presence of any other allergies
  • The specific components of the flu vaccine that caused the allergic reaction
  • The ingredients and manufacturing process of the meningococcal vaccine It's essential to inform your provider about these factors, as meningococcal vaccination is crucial for certain high-risk groups, including adolescents, college students living in dormitories, military recruits, and individuals with certain medical conditions, as outlined in the recommendations for adolescent immunization 1. Finding a safe way to receive this protection is worthwhile, and your healthcare provider can help determine the best course of action.

From the Research

Meningococcal Vaccine and Flu Vaccine Allergy

  • The provided studies do not directly address the question of whether someone allergic to the flu vaccine can receive the meningococcal vaccine.
  • However, the studies suggest that the meningococcal vaccine and flu vaccine are different types of vaccines with different components and mechanisms of action 2, 3, 4, 5, 6.
  • The meningococcal vaccine is designed to protect against Neisseria meningitidis, while the flu vaccine is designed to protect against influenza viruses.
  • There is no clear evidence to suggest that an allergy to the flu vaccine would preclude someone from receiving the meningococcal vaccine.
  • It is essential to consult a healthcare professional for personalized advice on vaccine administration, especially in cases of known allergies or sensitivities.

Vaccine Components and Allergies

  • The flu vaccine contains components such as egg proteins, which can cause allergic reactions in some individuals 4.
  • The meningococcal vaccine, on the other hand, contains components such as conjugated polysaccharides and proteins 2, 3, 5, 6.
  • The difference in components suggests that an allergy to the flu vaccine may not necessarily affect the administration of the meningococcal vaccine.

Consultation with Healthcare Professional

  • It is crucial to consult a healthcare professional before receiving any vaccine, especially if there are concerns about allergies or sensitivities.
  • A healthcare professional can assess individual circumstances and provide personalized advice on vaccine administration.
