Which vaccine is an example of killed vaccines?
Are there helpful bacteria in the H1N1 09 vaccine?
No, the vaccines are purified and treated to remove any such contaminants. Any bacteria mixed in with the virus and vaccine medium would not be helpful, the multi-use vials of vaccines contain preservatives to prevent bacterial growth. The H1N1/09 influenza is caused by a virus. Some particles of "dead" H1N1/09 virus (or in some types of the vaccines-weakened live virus), are the active ingredient in the vaccines that make our bodies become immune to that specific virus. Bacteria play no role in this process.
Asked in Vaccinations
What are the types of vaccines?
Killed vaccines: These are preparations of the normal (wild type) infectious, pathogenic virus that has been rendered non-pathogenic, usually by chemical treatment such as with formalin that cross-links viral proteins. Attenuated vaccines: These are live virus particles that grow in the vaccine recipient but do not cause disease because the vaccine virus has been altered (mutated) to a non-pathogenic form; for example, its tropism has been altered so that it no longer grows at a site that can cause disease. Sub-unit vaccines: These are purified components of the virus, such as a surface antigen. DNA vaccines: These are usually harmless viruses into which a gene for a (supposedly) protective antigen has been spliced. The protective antigen is then made in the vaccine recipient to elicit an immune response

What antivirus is in the swine flu vaccine?
Why is it difficult for scientist to develop a vaccine that is effective against HIV?
Asked in Science, Biology, Lymphatic System, Immune System
How does the immune system respond to a vaccine?
vaccines contain either live or killed antigen .live vaccines contain attenuated (weakened)viruses which do not have the ability to cause disease.when the vaccine is injected the body produces anti-bodies against it .next time when the virus enters by that time the body has enough anti-bodies to fight the disease causing virus successfully.
Asked in Similarities Between
What is the relationship between viruses and vaccines?
What are the effects of H1N1 vaccines?
The effects are to make you immune to the virus by stimulating your immune system to respond to the tiny amount of virus in the vaccine and build up a defense for if you are ever exposed to the virus in the "wild". The way the effects are created by vaccines is described in the related question below.
Asked in Lymphatic System, Immune System
How vaccines help the immune system?
Vaccines contain a 'dead' or weakened form of a virus. The immune system will still respond as if the virus were a threat (when it is completely harmless) and will destroy it, generating lymphocytes that will 'recognise' the virus if it ever enters the body again, allowing rapid destruction if the virus ever enters the body again.
