With a "live" vaccine, you're given a very small dose of the actual disease virus, or an inactived form of the virus. You become mildly ill, your body develops anti-bodies and helps you get well.
If you're ever exposed to the disease again (full-force), your body already has anti-bodies developed and you do not get the disease again.
Some vaccines are actually small doses of a disease so that your immune system builds it's self up against it. When you come in contact with the disease later, you are less likely to become ill.
A vaccine is an antigenic substance (dead viruses) that help the bodies natural defences to build up anti-bodies, so being able to recognise and fight against any live viruses enter the body.
Polio
Vaccine
You can take the vaccine but it will not stop the disease. Vaccinations prevent disease but they do not cure them.
Hepatitis C and hepatitis E have no vaccine to prevent the disease. Although there is no vaccine to prevent hepatitis D, you can only get this type if you're also infected with type B. Therefore, hepatitis B vaccine indirectly prevents hepatitis D.
POLIO
the vaccine has a little bit of the disease in it so your body gets an atibody for the disease so when the disease trys to attack you body you have an immune system to it
they prevent diseases very well but it is very hard to completely cure a disease so most vaccines strongly prevent diseases but there are always cases where the disease will break through.
It is a vaccine for the prevention of bacterial meningococcal disease and meningitis (infection of the covering of the brain and spinal cord).From manufacturer package literature:"Menactra vaccine is indicated for active immunization to prevent invasive meningococcal disease caused by N meningitidis serogroups A, C, Y, and W-135. Menactra vaccine is approved for use in individuals 9 months through 55 years of age. Menactra vaccine does not prevent N meningitidis serogroup B disease. "
A DNA vaccine contains DNA from a pathogen but cannot cause disease. When the vaccine is injected into a patient, the DNA directs the synthesis of a protein. Antibodies are produced by the body against the protein. If the patient contracts the disease in the future, the antibodies in his or her body will be able to provide protection.
The smallpox vaccine is an injection to prevent one from contracting smallpox. It has been used to help the body to develop immunity against the disease.
Once you have had Hepatitis B there is no need for a Hepatitis B vaccine. The vaccine is only effective for those who have not had the disease, it is used to prevent a hepatitis B infection.
Polio is NOT hereditary. It is caused by a virus, poliovirus, that is highly contagious. A vaccine exists to prevent catching the disease.
