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.
The flu shot is typically made from inactivated flu viruses that have been grown in chicken eggs. These viruses are then purified and broken down to create the vaccine that helps protect against the flu. So, in short, the source of the flu shot is a bunch of chicken eggs and some dead flu viruses.
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.
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.
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.
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.
There are some vaccines,but there are no such medicines that kills swine flu.
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.
The answer varies by state law.
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.
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).
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.
Originally in 2009 the vaccine for the pandemic swine flu was a monovalent vaccine, which means it was made to only prevent that one type of flu. Then for the 2010-2011 flu season, a trivalent vaccine was made for the regular flu just like every year. Trivalent means it is made to cover/prevent three different kinds of influenza virus infections. For the most recent flu season in the Northern Hemisphere, the "regular" flu shot contained the vaccine for swine flu and two others. So, the monovalent H1N1 vaccine covered only one type of flu: the pandemic swine flu. But the trivalent seasonal flu vaccines cover three types of flu (one of which, for the 2010 - 2011 flu season, is Swine flu H1N1/09).
