Which operation may be turned on in the body if you contract the influenza virus?

In those with healthy immune systems, the exposure to the virus causing the flu will trigger an immune response. This is how our bodies disable the virus so it can not continue to infect us. See the related question in the related questions section for more information on how the immune system works in these situations.


Should you get a flu shot when you have bell's palsy?

It won't hurt; the flu vaccine is non-virulent and won't lower your immune system while it makes antibodies to the influenza virus. It will still be able to fight off the Bell's Palsy virus (herpes).


How does a flu vaccine work to protect against the influenza virus?

A flu vaccine works by stimulating the body's immune system to produce antibodies that can recognize and fight off the influenza virus. When a person is vaccinated, their immune system is trained to recognize the virus and respond quickly if they are exposed to it in the future, helping to prevent infection or reduce the severity of symptoms.

What type of immune cells are in the Swine Flu?

None. Swine flu is an illness caused by the pathogen known now as swine flu virus, A-H1N1/09 influenza. The illness contains no immune cells, nor does the virus. Your body responds to the presence of the virus with an immune response that sends your own immune cells to the area of your body where the flu virus has invaded. It is your body's immune cells that enter the "fight" and eventually get rid of the virus by constructing the type of immune cells called antibodies that are a perfect fit to inactivate the specific virus so it can no longer cause cell damage and symptoms of the flu. Your body then remembers the antibodies that worked to inactivate the virus so it can use them in the future if you are ever exposed to that virus again.
