Urgent: Rare but Possible Vaccine Reactions Explained by Dr. Camille Braun
In a groundbreaking statement, Dr. Camille Braun from the Civil Hospices in Lyon has shed light on the rare but possible reactions to vaccines, providing crucial insights for both medical professionals and the general public. This breaking news is set to impact vaccination practices and public awareness globally.
Immediate Reactions: What You Need to Know
According to recent studies, immediate IgE-mediated allergies following vaccination are extremely rare, occurring in only 1 to 10 cases per 1,000,000 doses. Dr. Braun emphasizes that while these severe allergic reactions are uncommon, other immediate systemic reactions can occur, including fever, fatigue, headaches, hives, and even vasovagal reactions.
She clarifies the distinction between anaphylactic reactions, which typically happen within 30 minutes of injection, and vasovagal reactions, which are characterized by normal breathing, bradycardia, pallor, sweat, cold and moist skin, nausea, and vomiting.
Non-Immediate Reactions: Less Frequent but Notable
Non-immediate reactions are rarer and often involve skin symptoms, altered general condition, and joint pain. Dr. Braun explains that most local reactions, such as pain, redness, and edema, result from non-specific inflammation rather than allergic reactions.
She also discusses Arthus’ phenomenon, an inflammatory skin reaction mediated by IGG that can occur in subjects hyperimmunized by prior vaccine injections. This reaction typically develops within 6 to 12 hours and resolves within two to three days.
Subcutaneous Nodules and Other Rare Phenomena
Subcutaneous nodules, often associated with vaccines containing aluminum, can appear days to weeks after injection and resolve spontaneously within a year or more. These nodules do not reduce immunization and are generally not a cause for concern.
Allergies and Vaccinations: What You Should Know
Certain vaccine components, such as residual culture medium, conservatives, adjuvants, and stabilizers, can trigger allergic reactions. However, almost all these allergies do not constitute contraindications to vaccination.
Egg allergy is a concern for certain vaccines like yellow fever and tick encephalitis, requiring medical surveillance and sometimes consultation with an allergist. Gelatin allergy is also manageable, with alternative vaccines often available or skin tests recommended for prior assessment.
Expert Tips for Safe Vaccination
Dr. Braun advises that antibiotic allergies do not pose a problem for vaccination, as no cases related to antibiotic traces in vaccines have been described. Children under biotherapy can safely receive vaccines, often under hospital surveillance if necessary.
