Explanation
Immunoglobulin G (IgG) is the most abundant antibody in the human body.
It plays a crucial role in long-term immunity by recognizing and neutralizing pathogens.
IgG antibodies are produced after exposure to an antigen, such as a vaccine.
They persist in the bloodstream for an extended period, allowing the body to respond to subsequent infections with the same pathogen quickly.
IgG can also cross the placenta, providing passive immunity to newborns.
