The viruses that are put into flu vaccines must first be grown in a lab to produce enough to make a vaccine. The virus is grown in eggs during that culturing process. Most commonly they are grown in chicken eggs. The vaccines are not made from the eggs, but rather from the virus particles that are grown in the eggs along with the medium for administration, etc. See related questions below for more information.

What is the source of the flu shot?
The seasonal flu vaccine and the H1N1 flu vaccine are made by several independent manufacturers. Basically they grow the active ingredient in labs, then for large scale production, they grow it in chicken eggs. They extract it from the eggs and process it to make the vaccine. Most of the vaccines carry a warning that they may include some egg protein, so those who are allergic to eggs should not receive the commonly available vaccines.
What is a killed virus vaccines?
Cholera Vaccine. Flu vaccines formulated for injection use inert/inactive virus particles ("dead"), while flu vaccines for nasal mist are made as a LAIV (live attenuated influenza vaccine), which means they are "alive" but weakened chemically to prevent them from being able to cause illness.
If you are allergic to a lot of antibiotics should you get the H1N1 vaccine?
I just had the vaccination and the only thing the nurse asked me was if I am allergic to eggs (I'm not). As I understand it, flu vaccines are made from chicken eggs so this is a standard question. I am allergic to lots of things actually - including dust, pollen, some fruit and penicillin and I've had many seasonal flu vaccines over the years with no reactions. Just ask your doctor or nurse if you are concerned about an allergic reaction.
What is attenuated flu vaccine?
Attenuated simply means "weakened". An attenuated flu vaccine refers to vaccines made with live viruses (so you get a good immune response), but they have been weakened chemically so that they are unable to give you the flu. There are two types of flu vaccines available in the US. What is called inactivated, inactive or "dead" vaccine and what is called "live", weakened/attenuated vaccine. The injectable vaccines (intradermal and intramuscular) are made with "dead" viruses and the nasal spray is made with "live" attenuated viruses.
What medicine kills Swine Flu?
There are some vaccines,but there are no such medicines that kills swine flu.
What is the best way to ship the following products Explain your answer Flu vaccine?
The best way to ship flu vaccines is by a company such as FedEx. FedEx would be the best way to ensure the flu vaccines get to where they are going.
Can vaccines work on viruses?
Yes, a large percentage of vaccines are for viral infections, there are not many vaccines for bacterial infections but there are a few. The flu is caused by a virus, vaccinations against the flu work very well, for example.
Who can administer flu vaccines?
The answer varies by state law.
What is a vaccine that contains live weakened pathogens?
They are called live attenuated vaccines. Attenuated means weakened. The nasal mist flu vaccine is an example of a live attenuated vaccine. The vaccines for flu that are injected are made from pieces of viruses or "dead" viruses. See the related question below for more information on these two types of vaccines.
Does vaccination for flu cover you for all flu?
No. Each year for the US, the CDC has epidemiologists who study the flu viruses in other parts of the world and pick the three most likely to be causing illness in our part of the world in the next flu season. Those three are then made into vaccines to include in the "regular" flu shot. It is called a trivalent vaccine, because it contains three types of flu vaccines. Usually they predict very well in choosing the right viruses to use in the vaccines, but sometimes something totally unexpected comes along from a rapid mutation that is not in the vaccine (like with the 2009 Pandemic swine flu).
What side effect are you going to get after 3 years of having Swine Flu vaccinations?
You likely won't be able to get swine flu. As for any bad side effects, there are very few untoward side effects from flu vaccines. They have been proven safe and effective over decades of use of vaccines made in the same way with mostly all the same ingredients (with only the virus contained in the vaccines varying from year to year with each seasonal flu vaccine). Usually only a severe allergy to an ingredient in the vaccine is a serious side effect in these vaccines.
Vaccines against the flu are different every year why is this?
The most prevelent strains of the flu are used to develop the vaccines. These may not be the same strains as the year before. Also, the flu symptoms change due to the atmosphere and climate.
