Interferon alfa-2a, also known as Roferon-A, and interferon alfa-2b, also known as Intron A, are manmade interferons manufactured by recombinant DNA technology. These interferons belong to the class of drugs called biological response modifiers. This class of medicines stimulates the body's response to infection and disease.
