Final answer:
For individuals with an egg allergy, it is generally safe to receive any licensed flu vaccine; however, live attenuated flu shots are not recommended due to the risk of severe allergic reactions. Those with severe allergies should be vaccinated under medical supervision and may consider an egg-free, recombinant vaccine.
Step-by-step explanation:
Individuals with an egg allergy should consult with a healthcare provider, but generally, they can receive any licensed flu vaccine that is appropriate for their age and health status . This includes inactivated influenza vaccine (IIV) or recombinant influenza vaccine (RIV). A live attenuated influenza vaccine (LAIV) is not recommended as it is contraindicated for those with a history of severe allergic reactions to any component of the vaccine.
The traditional inactivated flu shot is manufactured using influenza virus particles grown in chicken eggs. These particles are harvested, chemically treated to be noninfectious, then purified for use in vaccinations. Although these shots contain a small amount of egg protein, the CDC states that those with a history of egg allergy of any severity can receive any licensed, recommended, and age-appropriate influenza vaccine. If an individual has experienced severe allergic reactions to egg proteins, the vaccination should be administered in a medical setting and supervised by a healthcare provider capable of managing severe allergic reactions.
However, if individuals are reluctant to be vaccinated with an egg-based vaccine due to a history of egg allergy or if a healthcare provider recommends against it, they may opt for an egg-free vaccine, such as a recombinant flu shot, which does not use chicken eggs in the production process.
It remains crucial to note that allergic reactions can occur from components of a vaccine other than egg proteins and that consultation with a healthcare provider is essential for a safe immunization experience.
