The theory behind the vaccine is that it is made up of weakened viruses but that form antibodies, which in turn build up the immune system that will fight the introduction of any pathogen the vaccine is intended to prevent.

It depends in what form the vaccine is given. If it is FluMist (through the nose) or a single-dose pre-filled syringe, then it does not contain thermisol (mercury). If it a multiple dose vaccine, then it contains therimosol to help preserve the vaccine. The FDA has suspended the limits of mercury in the H1N1 vaccine, which means the multiple dose vaccine may contain amounts of mercury higher than the FDA has previously allowed.
The DPT vaccine is injected into the muscle of body generally in arms.
A vaccine contain an inactivated virus ( a frequently situation), a preservative and an excipient.

Vaccine is a minidisease of which you want your body to be immune against. When you take the vaccine, your body destroys the virus and "remembers" it. You will then be able to get rid of the disease instantly.
A vaccine works by producing antibodies to immunize the body against the virus that vaccine is intended to protect against.
A vaccine works on the principle of stimulating the host's innate immune system. As such, a weakened form of a bacteria/virus is introduced and the body's reaction to it allows it to then fend off any later exposure to the full-strength form.
No, the H1N1 virus does not contain carcinogens.
no there is not any liophilized vaccine , but currently live attenuated vaccine that contain Theileria infected lynphoblast is used and is using in many country .
A vaccine contains the pathogen ( a foreign body which causes diseases/illnesses) which the virus is designed to provide protection for ie: a flu vaccine will contain a flu virus, measles has the measles virus etc... - but they have been treated so they are in effect dead and so will cause no symptoms, your body can only recognise a pathogen, it does not know that it is dead and can not harm you,so your body produces antibodies ( cells that fight off and remove pathogens from the body) to fight this vaccine, the antibodies remain in the body forever (unless you have an autoimmune/immunodeficiency illness) so when you come into contact with say the flu your body already has the antibodies and you don't get sick because your body removes the pathogen before it gets chance to take hold.
