Assuming the question is a typo for "Why do antibiotics not work on a flu?", the reason is quite simple. Influenza (Flu) is caused by a virus, not a bacteria or parasite.
When you have an infection, and your doctor prescribes you antibiotics, they are working on a bacterial or parasitic infection, not a viral infection.
Put quite simply, antibiotics are not effective whatsoever against viruses.

Does the flu vaccine include antibodies?
No, a flu vaccine triggers our bodies to make our own antibodies. The vaccine includes dead or weakened viruses that can't make us sick, but they will cause the immune response that creates the correct antibodies.
Do mothers transfer flu through lactating?
No, but they can transfer antibodies they developed from having had the flu or from a vaccination. Breastfeeding is an important part of providing protection to an infant with an undeveloped immune system by giving the antibodies by way of the milk.
How to get rid of Flu?
You cannot get rid of the flu. It is a virus. The symptoms can only be treated, until your antibodies can destroy the viral structure. This is why you get a flu shot because it significantly reduces the risk of getting the flu.
If your body is full of antibodies from a recent bout of chickenpox could you still come down with the flu?
Yes. The antibodies are very specific to each type of infection. So, the chicken pox antibodies would not be any protection against influenza viruses, and you could still come down with the flu if exposed to that virus. Ask the doctor who has treated the chicken pox when it would be okay to get a vaccination against the flu after the chicken pox.
Do you have antibodies against Swine Flu?
If you have been exposed to the virus that causes H1N1 Pandemic Swine Flu, either from having had the flu or from getting a vaccination for it, then your body will have made antibodies to the virus, as long as you have a healthy immune system. Once your body has made antibodies to that virus, you are immune to the disease if exposed in the future, as long as it is the exact same virus and not a mutated form of it. This immunity is provided by the previously made antibodies.
Who recovers more quickly from the flu someone who had a flu shot or someone who had no flu shot and why?
After a person receives a vaccination the bodies immunity system starts to prepare antibodies hence the person with a flu shot has greater chances of fighting aganist the disease
What happens if the patient has antibodies against influenza virus?
They should not get sick with that specific flu (but could with others).
How do white blood cells fight swine flu?
Your body develops antibodies that fight the bug. That is why you get a fever.
What is in a flue shots?
Dead flu viruses to trigger you body into making antibodies to give you immunity to tht strain of flu. Oh, and tiny microchips so the government can track you.
Why an influenzae vaccine prevents you from becoming sick with the flu?
The vaccine puts dead flu cells into your body. Because the cells are very weak, you immune system can completely kill that virus. After you immune system kills the virus, antibodies are still left over in your blood stream. So, if you are exposed to the flu, the already made antibodies can kill the flu virus before it spreads and gets too serious for your immune system to overcome.
Will the flu shot decrease your immune system even more?
No, a flu shot tricks your immune system to think you have the flu and it makes and sends antibodies to fight the infection, if you have an otherwise healthy immune system. The immune responses do not "decrease" your system's ability to protect you and actually may help you respond more quickly to the next antigen (causative organism). A flu shot just introduces a "dead" or weakened flu virus to your system so it can work out how to make antibodies against that organism in advance of a real infection by a full-strength flu virus. The immune system in healthy individuals is ready and able to go to work to fight infections, and the more organisms it works against, the more patterns for antibodies there are in your immune system "memory". Some of the old patterns may match the new organism well enough to provide protection, or make it easier for your immune system to build slight variations in them to work on the new antigen. So, exposure to more organisms may actually help prime your immune system so it can respond more quickly to any "invasion".
Is there a new flu going around fall 2017?
Yes, and since the new flu that caused the pandemic in 2009 (H1N1/09 "Swine flu") there have been other new types identified (and even some new strains of avian flu have been identified) around the world. The viruses that cause the flu are mutating into new types of flu all the time. Cold viruses also mutate easily and quickly, this is a reason that vaccines can not be developed in time before they mutate again leaving the vaccine ineffective). Sometimes our immune systems have antibodies against older types of flu that will work to prevent the new types that are not that much different, but then other times the new influenza virus will have mutated into types for which our prior immunities will not be effective to prevent the new flu from making us ill. We will have to either get vaccines made as we did in 2009, or we will have to leave it to our bodies to make new antibodies that will block the new flu, but we will feel the symptoms of the flu in the interim.
