Vaccine Component Panel

Vaccine Component Panel

Vaccine ingredients often contain components that can be potential allergens to some individuals. The main components of a vaccine include: active immunizing antigens, conjugating agents, preservatives, stabilizers, antimicrobial agents, adjuvants and a culture media. Most allergens come from the culture and stabilizer proteins from egg, gelatin and yeast.

Anaphylaxis after immunization is rare in all age groups. However, personnel administering vaccinations need to be prepared for such emergencies. Most cases of anaphylaxis after vaccination occur in individuals with known history of anaphylactic episodes. If someone has a known allergy to eggs, chicken, gelatin or yeast, request an ingredients list prior to any vaccination.
