Antibodies From Hen Eggs for Human Healthcare

Abstract

The blood of almost all animals contains proteins known as antibodies. The types of antibodies differ from one animal to another, but the main purpose of all antibodies is to prevent animals from getting sick. Antibodies help animals to protect themselves against bacteria, viruses, and other dangerous invaders. Scientists have found a way to obtain antibodies from some animals and use them to improve human health. Antibodies from hens are especially promising because large quantities of hen antibodies, known as IgY, can be obtained from their eggs—a process that does not hurt the birds at all. IgY is a very stable antibody that has been used to treat human diseases like dental cavities and stomach ulcers. Soon, we may even have an IgY that can treat or prevent COVID-19 and other viral pandemics. Therefore, IgY is a very valuable resource that will continue to improve human healthcare.
