The process begins with an initial evaluation by an allergist, who will perform skin tests or blood tests to identify specific allergens. The shots are then administered in two phases: the build-up phase and the maintenance phase. During the build-up phase, which lasts 3 to 6 months, the child will receive shots 1 to 2 times per week. The maintenance phase involves receiving shots less frequently, usually once a month, for 3 to 5 years.
