the ability of the immune system to defend against the flu?

Question

influenza viruses undergo frequent genetic mutations and rearrangements that produce viruses with new combinations of surface antigens. how would this affect the ability of the immune system to defend against the flu

Answer 1

the immune system must recognize an antigen to mount a specific defense against it. If the virus is virulent enough, it can damage enough cells in replicating itself that the host dies before the system develops enough antibodies to kill it off.

Answer 2

Regular intake of natural Vitamin C keeps the immune system of the body in top form. As the influenza or any other virus can mutate, the Vitamin has the ability to ward off the infections and ensure effective antigens. Vitamin C (found in citrous fruits like lemon) is one of the best chemicals to build and sustain an effective immune system as proved by medical research so far.

"Not only does a high vitamin C intake markedly reduce the severity of a cold, it also effectively prevents secondary viral or bacterial complications. Vitamin C works by stimulating the immune system and protecting against damage by the free radicals released by the body in its fight against the infection".

In other words the immunity system responds to take on the challenges of the viruses or any other microbes causing infections and illness in our body when Vitamin C is present in the system.
