Study subjects were evaluated for any association  between  preventive  immunization  against  rubella,  measles,  typhoid  fever, smallpox and incidence of atopic dermatitis, allergic rhinitis, and asthma.There was no increased risk of allergy incidence in the majority of vaccinated subjects against rubella, measles, typhoid  fever, or smallpox (OR  from 0.42 (ppppp=0.005), varicella (OR=1.18; p=0.003); rhinitis and AR following vaccination against measles (respectively OR=1.22; pp=0.0002).  No  higher risk of allergic  diseases  was  demonstrated  in vaccinated individuals diagnosed by doctor in an outpatient setting.These data do not demonstrate a causal relationship between vaccinations and allergic conditions. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/587 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/587/522
