A vaccine is defined as the preparation of a biological combination which is said to cause immunity to a disease or a condition. A vaccine usually contains agents which are similar to disease causing micro-organisms. These are made from the weakened or dying forms of the microbe that is responsible for the disease or some of the toxins that are related to the disease itself. The agent is used to stimulate the immune system so that it recognizes that agent as a risk or a foreign matter. This causes the body to destroy it and memorize it, allowing the body to be able to defend itself if it comes into contact with the agent again in the future. Vaccines are known to be used to prevent a future infection or therapeutic to help fight against conditions which are still being investigated. It is important to understand that the use of a vaccine does not mean that an individual may be completely immune from the disease itself. In fact, it is possible to have positive results from a vaccine but still become ill or affected by the disease itself when the individual has come into contact with the agent again in the future. Sometimes the body is also not able to respond to the vaccine the way that it was supposed to work. Although some vaccines work positively for some people, other people may experience that there is no positive result at all. Even if someone develops antibodies against a disease or condition, the immune system may not be able to fight off the infection instantly. In this situation, the vaccine just allows the body to be able to experience the infection in a less severe manner and helps the immune system to respond to the infection faster, leading to a quicker recovery rate. The overall efficiency of a vaccine depends on many different factors. These can include the disease itself and its severity, the strain of the vaccine being use, if the individual was on a vaccination schedule and followed it correctly, if the individual is considered to have a body which simply doesn’t respond to vaccinations, and other factors such as age or genetic issues. It has been proven that some individuals are almost immune to the use of vaccines because their bodies are not able to generate antibodies even when they have been vaccinated. Even if an individual is not immune, the goal is that the individual who has been vaccinated should be able to experience a more mild case of the disease as a result.
