EMPOWERING HUMANITY TO THRIVE AGAIN
Antigens are molecules capable of stimulating an immune response. Typically antigens are foreign proteins that enter the host body via infection. Bacteria and viruses contain antigens that are found on the surface.
Each virus has its own unique shaped antigen, that can be bound to by an antigen-specific antibody. When someone becomes infected with COVID-19, the immune system releases antibodies that bind to antigens to help eliminate the pathogen.
