DTP, Tetanus Vaccinations May Cause Allergy Symptoms
Chronic sinusitis, often associated with asthma and allergic rhinitis, is the most common chronic condition in the United States. These three conditions are among the five most common diagnoses given to children and adolescents (aged 15 and under), accounting for 9.4 million ambulatory care visits annually.
Previous research suggests that diptheria and tetanus toxoids and pertussis (DTP) and tetanus vaccinations induce allergic responses, an association examined further in this study of 13,944 children (two months to 16 years old).
Data from the Third National Health and Nutrition Examination Survey provided information on DTP or tetanus vaccination, allergy history, and allergy symptoms in the previous 12 months.
Vaccinated children were twice as likely to have a history of asthma, and 63% more likely to have an allergy-related symptom in the previous 12 months, compared with unvaccinated children. These associations were strongest among younger children (5-10 years of age).
These findings suggest that DTP and/or tetanus vaccination may produce delayed effects in children, specifically an
increased risk of asthma or allergy-related symptoms. The authors conclude that because nearly all children receive at least one dose of DTP vaccine, the number of allergies or allergy-related conditions attributable to vaccination may be high. As the authors state: "The well-documented public health benefits of the DTP and tetanus vaccines must be considered in light of these potential long-term risks..."
