One of the most common of all allergies has to be Cows’ Milk Protein Allergy (CMPA), which is one reason why DBV Technologies (www.dbv-technologies.com/en) has focused on this allergy amongst others.
CMPA affects 2 to 3% of infants and young children. Although many sufferers grow out of this particular allergy, it can still be very unpleasant while it lasts. Symptoms include vomiting, diarrhoea and skin rashes, not to mention, in more severe cases, anaphylactic shock. This is where the Viaskin Milk patch comes in. All you would have to do is place the patch on your arm, as shown in the photograph below, and the cows’ milk antigens contained in the patch will start to work on tolerizing your body to this foodstuff. Viaskin is what’s called an epicutaneous patch, which points to its mechanism of action, which works by delivering the antigens through the body’s epidermis or skin. This is done through a condensation chamber, which is created by the heat of the body and subsequent production of sweat which then solubilizes the dry powder containing the antigens. In this form, the antigens can pass through the skin.
