What does the body make more of when you have an infection?

The first that comes to mind is: White Blood Cells (WBC), these blood cells work with our immune systems to fight infections and many are created to fight the infection. There are many other things the body makes more of when fighting infections, another example is the antibodies that are created by our immune systems that can neutralize microbes when made to fit them perfectly. These are made also when we get immunizations so they can prevent infections, like a flu vaccination.


Why do some people who receive flu vaccines still get the flu?

Unless you are exposed to the flu before the vaccination is effective, it would not actually be the flu that causes these flu-like symptoms after a vaccination. It is not uncommon for symptoms that are flu-like (mild fever, achy muscles, headache, malaise, etc.) to occur immediately after receipt of a flu vaccination. This is not an indication of a viral infection, but, rather, these symptoms are due to the body's normal immune response to the vaccine and should go away within a couple of days. Since it is the normal body reaction to a vaccination, you would not be contagious to others who are healthy, either. Vaccines trick the body into thinking there is an infection when there isn't. This causes the immune response that begins the process of creating the antibodies that will be able to inactivate the type of pathogen contained in the vaccine if you should be exposed to the same one in the wild after the vaccination has taken effect. [This takes usually around two weeks time after the inoculation in otherwise healthy people who are adults or children over 10 years old. Children 6 months old up to 10 need a series of vaccinations that take longer before effective. Babies under 6 months old cannot be vaccinated because their immune systems are too immature.] The immune response not only causes antibody production, but also results in the other germ-fighting mechanisms (which can include slight fever and the other flu-like symptoms). Otherwise healthy people are not able to catch the flu from flu vaccinations because the pathogen in the vaccine is either totally inactivated/"dead" or is severely weakened so that it is not able to cause the infectious disease. See also the related questions below for more information about the processes of an immune response.

What is the meaning the immunity?

Our immune systems are designed to keep track of the various infections that can be caused by pathogens once they encounter them. This helps to increase our immunity as this information helps the bodies immune system to fortify itself against further attacks by the same pathogen. If immunity is increased by means other than acquiring the disease, then it is known as passive immunity. e.g. Vaccination( in this weak pathogens are injected in the body and this helps the body's immune system to remember and then identify it to fortify the body for any future attacks by that pathogen)
