Chicken Egg Yolk-IgY: Passive Immunization Promising Targeted Therapy of COVID-19 Pandemic

The world is threatened by the lethal effects of Coronaviruses (CoVs) that associated with major respiratory disorders. The CoVs are large, enveloped, positive-stranded RNA and therefore, it is considered a complicated virus structure. The spike (S) is the major protein that exists in CoV’s structur...

The CoVs are large, enveloped, positive-stranded RNA and therefore, it is considered a complicated virus structure. The spike (S) is the major protein that exists in CoV’s structure regulates the viral access to the host using angiotensin-converting enzyme 2 (ACE2) receptor for both severe acute respiratory syndrome Coronaviruses-2 (SARS-CoV-2) and/or SARS-CoV initiates the animal/human disease and elevated immune responses. The receptor binding domain (RBD) in the S-proteins is essential for the CoVs-gene sequences; however the literature discussed CoV S-protein in relation to receptor-binding is little. Therefore, finding a natural antiviral to limit the spreading of CoVs is important. Herein, Immunoglobulin (Ig) Y is considered a kind of passive immunizations, represents 60% of the egg-yolk and can preventing many infectious diseases due to the particularities of IgY-molecule shape functional bioactivity to combat the pathogens. Comparing IgY to other Ig(s) antibodies, it makes the minimal animal stress, produces the lowest responses to mammalian factors.
