The global prevalence of food allergy (FA) during the nursing period is 6–8 percent, with Turkey reporting a rate of 5.7 percent. The goal of this research is to see if the prevalence of food allergies (FA) increases in children who have been vaccinated against rotavirus. The data of 681 newborns who are still being followed up on were reviewed retrospectively. Children who did not attend all of their well-child follow-up visits at our clinic were omitted from the research. Furthermore, children who had already been diagnosed with allergy or who had a known gastrointestinal system condition were excluded from the trial.

Twelve patients were diagnosed with food allergies after being immunised against rotavirus. Three of the children had a history of allergies in their family. Three of the 12 patients detected after immunisation were vaccinated with pentavalent vaccine and nine with monovalent vaccine. Food allergy was discovered in 9 children in the monovalent vaccination group and 3 children in the pentavalent vaccine group. The difference in food allergy prevalence between the two immunisation groups was not statistically significant. Although it is widely assumed that food allergy, and particularly cow’s milk protein allergy (CMPA), increases in newborns vaccinated against rotavirus, no significant increase in food allergy prevalence was detected in this study.
