Interferon are small proteins (cytokines) that enhance the immune system and defense against viruses and bacterial infections.
Interferon stimulates the infected cells and those nearby to produce proteins. These proteins prevent the virus from replicating within them. Further production of the virus is inhibited<span> and the infection is stemmed.
