The DTaP vaccine is administered to individuals who have experienced a spider bite because tetanus spores are present in the soil and environment and may be transferred into the patient’s bloodstream with the bite. This response most appropriately addresses the patient’s specific question and concerns. Although it is true that the DTaP is administered to all patients who have experienced a break in skin by a potentially contaminated object, this does not address the question as well as the previous response. The DTaP is important for protecting the elderly and small children from pertussis, but this does not address the patient’s question. DTaP boosters are necessary for continued immunity; however, this does not address the patient’s concerns.
