  https://www.ncbi.nlm.nih.gov/books/NBK538192/

  Egg allergy is IgE-mediated and healthy individuals are capable of generating antigen-specific IgE upon exposure to egg allergens. […] The consensus is that IgE responses are genetically controlled by MHC-linked genes that are found on chromosome six. […] The term egg allergy refers to an adverse immunological response to exposure to allergens found in egg white or egg yolk. It is the second most common food allergy in the United States after milk allergy. […] Estimating the prevalence of food allergies is challenging for several reasons. […] Hen egg allergies often present within a year of age with no distinction between either gender. […] As opposed to other food allergies such as tree nut, peanut, or fish, egg allergy typically resolves or improves relatively earlier in life. […] A significant majority of patients with hen egg allergy will develop tolerance to hen egg allergens by the time they reach school age. Some, however, build tolerance only in adolescence.

  Hen’s egg allergy is the second most common food allergy in infants and young children (cow’s milk is the most common). […] The epidemiology, pathogenesis, clinical features, and diagnosis of egg allergy are presented in this topic review. […] The prevalence of hen’s egg allergy confirmed by oral challenge was 1.6 percent of children three years of age in an unselected population in Denmark. […] A subsequent meta-analysis of the prevalence of food allergy estimated that egg allergy affects 0.5 to 2.5 percent of young children. […] An Australian population-based cohort study challenged children using raw egg white and reported an egg allergy prevalence of 9.5 percent at one year and 1.2 percent at four years. […] Challenge-proven egg allergy in South African toddlers (12 to 36 months) was 1.9 percent for raw egg white and 0.8 percent for cooked egg. […] New-onset egg allergy in adults is rare and is limited to case reports.

A subsequent meta-analysis of the prevalence of food allergy estimated that egg allergy affects 0.5 to 2.5 percent of young children. There were several limitations to the meta-analysis. There was significant variability in study design that made direct comparisons difficult. The majority of studies included in the meta-analysis were based upon self-reports of food allergy, which tend to overestimate the prevalence. Some studies used skin prick test and food-specific IgE levels to confirm sensitization to the allergen, but not all diagnoses were challenge proven. The form of egg used in challenges also contributes to the variability in egg allergy prevalence. An Australian population-based cohort study challenged children using raw egg white and reported an egg allergy prevalence of 9.5 percent at one year and 1.2 percent at four years. Challenge-proven egg allergy in South African toddlers (12 to 36 months) was 1.9 percent for raw egg white and 0.8 percent for cooked egg.

  Food allergies represent a significant global health concern, with increasing prevalence and diverse epidemiological patterns observed worldwide. […] The estimated global prevalence of food allergies is approximately 8% in children and 10% in adults. […] In the United States, large-scale population-based surveys have provided insights into the prevalence of food allergies, revealing rates of 7.6% among children and 10.8% among adults. […] Studies in Europe, involving birth cohorts of over 12,000 participants, have revealed country-specific differences in food allergy incidence. For example, among children 2 years of age, egg allergy had a mean incidence of 1.23%, with rates ranging from 0.07% in Greece to 2.18% in the United Kingdom. […] Regional variations were present as well, following an expected pattern fish and shrimp allergies were more commonly reported in the Mediterranean area and Iceland, while nut, fruit, and vegetable allergies were more commonly reported in Central Europe. […] Conversely, food allergies are considered relatively uncommon in many Asian and African countries. […] The development of food allergies is influenced by various risk factors, contributing to the variability in prevalence observed worldwide.

The epidemiology, pathogenesis, clinical features, and diagnosis of egg allergy are presented in this topic review. The prevalence of hen’s egg allergy confirmed by oral challenge was 1.6 percent of children three years of age in an unselected population in Denmark. A subsequent meta-analysis of the prevalence of food allergy estimated that egg allergy affects 0.5 to 2.5 percent of young children. There were several limitations to the meta-analysis. There was significant variability in study design that made direct comparisons difficult. The majority of studies included in the meta-analysis were based upon self-reports of food allergy, which tend to overestimate the prevalence. Some studies used skin prick test and food-specific IgE levels to confirm sensitization to the allergen, but not all diagnoses were challenge proven. The form of egg used in challenges also contributes to the variability in egg allergy prevalence. An Australian population-based cohort study challenged children using raw egg white and reported an egg allergy prevalence of 9.5 percent at one year and 1.2 percent at four years. Challenge-proven egg allergy in South African toddlers (12 to 36 months) was 1.9 percent for raw egg white and 0.8 percent for cooked egg.

[…] OBJECTIVE: To establish the incidence and course of challenge-confirmed HEA in children, from birth until the age of 24 months, in different European regions. […] RESULTS: Across Europe, 12 049 newborns were enrolled, and 9336 (77.5%) were followed up to 2 years of age. In 298 children, HEA was suspected and DBPCFC was offered. HEA by age two was confirmed in 86 of 172 challenged children (mean raw incidence 0.84%, 95% confidence interval (95% CI) 0.67-1.03). Adjusted mean incidence of HEA was 1.23% (95% CI 0.98-1.51) considering possible cases among eligible children who were not challenged. Centre-specific incidence ranged from United Kingdom (2.18%, 95% CI 1.27-3.47) to Greece (0.07%).

  Food allergies represent a significant global health concern, with increasing prevalence and diverse epidemiological patterns observed worldwide. […] The estimated global prevalence of food allergies is approximately 8% in children and 10% in adults. […] In the United States, large-scale population-based surveys have provided insights into the prevalence of food allergies, revealing rates of 7.6% among children and 10.8% among adults. […] Studies in Europe, involving birth cohorts of over 12,000 participants, have revealed country-specific differences in food allergy incidence. For example, among children 2 years of age, egg allergy had a mean incidence of 1.23%, with rates ranging from 0.07% in Greece to 2.18% in the United Kingdom. […] Regional variations were present as well, following an expected pattern fish and shrimp allergies were more commonly reported in the Mediterranean area and Iceland, while nut, fruit, and vegetable allergies were more commonly reported in Central Europe. […] Conversely, food allergies are considered relatively uncommon in many Asian and African countries. […] The development of food allergies is influenced by various risk factors, contributing to the variability in prevalence observed worldwide.

  Hen’s egg allergy is the second most common food allergy in infants and young children (cow’s milk is the most common). The epidemiology, pathogenesis, clinical features, and diagnosis of egg allergy are presented in this topic review. The prevalence of hen’s egg allergy confirmed by oral challenge was 1.6 percent of children three years of age in an unselected population in Denmark. A subsequent meta-analysis of the prevalence of food allergy estimated that egg allergy affects 0.5 to 2.5 percent of young children. There were several limitations to the meta-analysis. There was significant variability in study design that made direct comparisons difficult. The majority of studies included in the meta-analysis were based upon self-reports of food allergy, which tend to overestimate the prevalence. Some studies used skin prick test and food-specific IgE levels to confirm sensitization to the allergen, but not all diagnoses were challenge proven. The form of egg used in challenges also contributes to the variability in egg allergy prevalence. An Australian population-based cohort study challenged children using raw egg white and reported an egg allergy prevalence of 9.5 percent at one year and 1.2 percent at four years. Challenge-proven egg allergy in South African toddlers (12 to 36 months) was 1.9 percent for raw egg white and 0.8 percent for cooked egg. New-onset egg allergy in adults is rare and is limited to case reports.

  Egg allergy is IgE-mediated and healthy individuals are capable of generating antigen-specific IgE upon exposure to egg allergens. […] The consensus is that IgE responses are genetically controlled by MHC-linked genes that are found on chromosome six. […] The term egg allergy refers to an adverse immunological response to exposure to allergens found in egg white or egg yolk. It is the second most common food allergy in the United States after milk allergy. […] Estimating the prevalence of food allergies is challenging for several reasons. […] Hen egg allergies often present within a year of age with no distinction between either gender. […] As opposed to other food allergies such as tree nut, peanut, or fish, egg allergy typically resolves or improves relatively earlier in life. […] A significant majority of patients with hen egg allergy will develop tolerance to hen egg allergens by the time they reach school age. Some, however, build tolerance only in adolescence.

  Epidemiology […] General surveys report that as many as 25-30% of households consider at least 1 family member to have a food allergy. However, this high rate is not supported by controlled studies in which oral food challenges are used to confirm patient histories. […] Comprehensive studies that include oral food challenges are few in number. Considering allergy to milk, egg, peanut, and seafood in a meta-analysis of 6 international studies using oral food challenges, estimated rates of 1-10.8% were obtained. […] In a meta-analysis including allergy to fruits and vegetables (excluding peanut), only 6 international studies included oral food challenges, and estimates of allergy varied widely from 0.1-4.3% for fruits and tree nuts to 0.1-1.4% for vegetables to under 1% for wheat, soy, and sesame. […] Among children, males appear to be more affected; among adults, females are more frequently affected. The prevalence of food allergies has been estimated to be up to 8% in infants and children and 3.7% in adults. […] However, variations in prevalence have been reported according to method used (self-report, testing, physician evaluation), geographic region, and foods included in the assessment. […] In a population-based survey study of 40,443 US adults, an estimated 10.8% were food allergic at the time of the survey, whereas nearly 19% of adults believed that they were food allergic.

  Vaccination of egg-allergic individuals has been a historical concern, particularly for influenza and measles-mumps-rubella-varicella vaccines that are developed in chicken egg embryos or chicken cell fibroblasts. […] Local epidemiological studies have shown that 0.4%-0.7% of Hong Kong children were reported by their parents to have had an adverse reaction to intake of a hens egg. […] A recent United Kingdom multi-centre study found that more than a third of patients with suspected egg allergy who were referred to a tertiary allergy centre for vaccination were not actually egg allergic, and all were vaccinated successfully. […] Despite the paucity of evidence, there remains some concern that administration of vaccines that could contain egg proteins, notably ovalbumin, might cause allergic reactions in egg-allergic subjects.

[…] The median time to develop tolerance has been reported to be from 3 to 9 years of age, and 5%-10% of children reported that their egg allergy persisted until 18 years of age. […] The prognostic factors associated with the egg allergy tolerance acquisition have been reported to include the following: characteristics of the initial reaction at the time of egg consumption, baseline egg skin prick test wheal size, and baseline egg-specific IgE level at diagnosis. […] We propose EWsIgE12mo as an early predictor for future tolerance. […] It is important to predict which children with egg allergy are likely to have persistent allergy because it is necessary to identify the candidates for emerging food allergy therapies including oral immunotherapy, which can carry risks and be costly.

However, this high rate is not supported by controlled studies in which oral food challenges are used to confirm patient histories. […] Comprehensive studies that include oral food challenges are few in number.

[…] In a meta-analysis including allergy to fruits and vegetables (excluding peanut), only 6 international studies included oral food challenges, and estimates of allergy varied widely from 0.1-4.3% for fruits and tree nuts to 0.1-1.4% for vegetables to under 1% for wheat, soy, and sesame. […] Among children, males appear to be more affected; among adults, females are more frequently affected. The prevalence of food allergies has been estimated to be up to 8% in infants and children and 3.7% in adults. […] However, variations in prevalence have been reported according to method used (self-report, testing, physician evaluation), geographic region, and foods included in the assessment. […] In a population-based survey study of 40,443 US adults, an estimated 10.8% were food allergic at the time of the survey, whereas nearly 19% of adults believed that they were food allergic. Nearly half of food-allergic adults had at least 1 adult-onset food allergy, and 38% reported at least 1 food allergy-related ED visit in their lifetime.
