What are the key differences between human and humanized monoclonal antibodies in terms of their effectiveness and safety profiles in treating diseases?

Human monoclonal antibodies are derived from human cells and are less likely to cause immune reactions in patients. Humanized monoclonal antibodies are partially derived from non-human sources and may have a higher risk of immune reactions. In terms of effectiveness, both types of antibodies can be effective in treating diseases, but human monoclonal antibodies may have a slight advantage due to their fully human origin.
