No, the "pneumonia vaccine" is to protect against several types of pneumonia that are common and will not protect against the A-H1N1/09 virus. See related questions below.
A vaccine works by producing antibodies to immunize the body against the virus that vaccine is intended to protect against.
In veterinary medicine, that is a vaccine against Distemper, Adenovirus type 2 and Parvo Virus
killed virus
A vaccine is essentially a weakened or dead version of the virus. This essentially "infects" you with the virus and causes the body's immune system to respond and create anti-bodies that will kill the real virus if it does ever get into your system.
The body reacts to a vaccine by producing antibodies to protect against the disease.
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.
how do vaccines help the bodys natural defences against viruses ??
Varicella Zoster is a type of herpes virus that is commonly the cause of chickenpox. The chickenpox vaccine, often called the Varicella vaccine, is a live virus vaccine to protect against chickenpox, as it can be extremely dangerous in adults. As shingles can also result from the same virus, the vaccine protects against that as well.
There is no known vaccination for the virus yet. Only experimental procedures have been used.
To corrupt a vaccine in Pandemic 2, you can use Genetic Hardening. This ability allows you to make the virus more resistant to any vaccine that is developed, thus hindering efforts to combat it effectively. Keep in mind that the vaccine can still be developed, but it will be less effective against your virus.
