Explanation / Answer
Immunoglobulin A is rapidly produced after a vaccinated individual's re-exposure to the exact same antigen. Immunoglobulin A has a role in immune response in mucus membrane and gastrointestinal tract. There are two subtype of IgA, IgA1 and IgA2. Immunoglobulin A provide immunity against microbes which are present and multiply in body secretions like mucus, tears etc.
