Cow’s milk allergy is a common diagnosis in infants and children, and it manifests as a hypersensitivity reaction to the allergenic

proteins in cow milk. Cow milk contains about 20 distinct protein components. The primary allergens are casein protein (alpha-s1-, alpha-s2-, beta-, and kappa-casein) and whey protein (alpha-lactalbumin and beta-lactoglobulin). There are several allergy treatments available, but they are just temporary. Developing a vaccine against milk allergy may appear utopian. Epitopes were found and exploited to build a multiprotein vaccine in this immunoinformatics study. Immunoinformatics techniques were used to predict T- and B-cell epitopes. Adjuvants were used to boost the vaccine’s antigenicity. The created vaccine design was shown to be soluble, antigenic, non-allergenic, and non-toxic.

Highlights

• Cow milk contains around 20 proteins which may cause allergy.
• Immunoinformatics approach is used to design vaccine.
• Allergens are identified and vaccine is constructed and tested in-silico.
