Explanation:
When a person is infected by a virus, the infected person's body develops antibodies as an immune response to act against the virus. Antibodies are produced as part of humoral immunity.
Antibodies work by neutralizing the viral activity, agglutination, phagocytosis or by complement system.
Antibodies are protein compounds which can recognize the invading pathogens and attack them.
