Type 1 hypersensitivity occurs mainly due to action of which immunoglobulin?

Type 1 hypersensitivity occurs mainly due to action of which immunoglobulin? Correct Answer IgE

IgE antibody isotype molecules are bound to receptors on mast cells as well as basophils. When there is a cross-linking mechanism between IgE antibody isotype molecules, the degranulation mechanism gets triggered. This takes place as a clinical response of type 1 hypersensitivity which usually takes place after vaccine dosage supervision is attempted successfully.
