Aluminum content of vaccines used in Turkey

Aluminum salts have been used in the preparation of a number of vaccines, toxoids, and allergen injectants as an adjuvant for many years. Although aluminum allergy is rare, there are many reported cases caused by aluminum-precipitated vaccines or hyposensitization therapy. Therefore, determination of the aluminum content of these vaccines is necessary information regarding adverse reactions related to these vaccines. In the present study, the aluminum contents of several vaccines (n = 19) routinely used in Turkey were, determined by electrothermal atomic absorption spectrophotometry. We found that aluminum levels in the vaccines ranged from 0.0 to 1438 mg/L.
