Explanation:

Vaccines aim to stimulate the immune system to produce antibodies. IgG is the most abundant antibody in the bloodstream and plays a crucial role in long - term immunity. IgA is mainly found in mucosal areas (e.g., respiratory and digestive tracts), IgD has a less - clear function in immunity, and IgE is associated with allergic reactions and defense against parasites. Since vaccines are often designed to provide broad - based and long - lasting immunity (systemic immunity), they usually target the enhancement of IgG.

Answer:

IgG
