A virus-bound antibody binds to receptors, called Fc receptors, on the surface of phagocytic cells and triggers a mechanism known as phagocytosis, by which the cell engulfs and destroys the virus. Finally, antibodies can also activate the complement system, which opsonises and promotes phagocytosis of viruses.
The immune system's job: defend against disease-causing microorganisms. Its goal is to keep us healthy. The immune system is a vast and complex interconnected network of many different organs, cells and proteins that work together to protect the body from illness.

And a lot of your innate immune system's functionsMoreThere's something to be said for brute force. And a lot of your innate immune system's functions aren't exactly subtle for example your body's very first line of defense is a simple physical barrier.
Load up on water, soups, and warm broths. Adding ginger, pepper, and garlic to your soups will help your body fight the viruses. The allicin present in garlic has antibacterial, antifungal, and antiviral properties. Studies have shown that eating raw garlic every day can boost immunity against the virus.
Immunity to norovirus is short-lived A norovirus infection provokes a robust immune response that eliminates the virus in a few days. However, the response appears to be short-lived. Most studies have found that immunity guarding against reinfection with the same norovirus strain lasts less than six months.
The innate immune system is the body's first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the "nonspecific" immune system.
The first line of defence (or outside defence system) includes physical and chemical barriers that are always ready and prepared to defend the body from infection. These include your skin, tears, mucus, cilia, stomach acid, urine flow, 'friendly' bacteria and white blood cells called neutrophils.
skinThe first line of defence is your innate immune system. Level one of this system consists of physical barriers like your skin and the mucosal lining in your respiratory tract. The tears, sweat, saliva and mucous produced by the skin and mucosal lining are part of that physical barrier, too.
