Do vaccinations make children allergic?
Townsend Letter for Doctors and Patients, Nov, 2001, by Alan R. Gaby
The association of DTP or tetanus vaccination with allergies and allergy-related respiratory symptoms was assessed among 13,944 U.S. children and adolescents (aged 2 months to 16 years) participating in the Third National Health and Nutrition Examination Survey. The odds of having a history of asthma was twice as great among vaccinated children as among unvaccinated children (adjusted odds ratio = 2.00; 95% confidence interval [CI], 0.59-6.74). The odds of having had any allergy-related respiratory symptom in the past 12 months was 63% greater among vaccinated than unvaccinated children (adjusted odds ratio = 1.63; 95% CI, 1.05-2.54).
Comment: The prevalence of allergic disorders has increased by 50-100% among adults and more than doubled among children during the past 20 years. While there are many possible explanations for this increase (such as more pollution and more additives in our food) widespread use of vaccinations may also be a contributing factor, Animal and human studies have shown that DTP and tetanus vaccinations induce allergic responses. While there is still no proof that vaccinations make people allergic, it is important to weigh all of the potential risks and benefits when making public-health and personal decisions about vaccination.
