Prevention had been long aged cherished than cure.
A cure can never be 100% efficient in as much as that ailment always forget a sign with the body, be it scars, phantom pain or permanent damage. Aside from that, Cure is sometimes painful, reticent and costlier than prevention.
However, some diseases exist that can’t be cured yet. Hence Vaccination. With continued immunization programmes, such diseases may no longer be a threat.
Immunization is one of the biggest health successes of the last century.
A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins.
The agent stimulates the body’s immune system to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future. Vaccines can be prophylactic (to prevent or ameliorate the effects of a future infection by a natural or “wild” pathogen), or therapeutic (to fight a disease that has already occurred, such as cancer). Some vaccines offer full sterilizing immunity, in which infection is prevented completely.
The administration of vaccines is called vaccination. Vaccination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the restriction of diseases such as polio, measles, and tetanus from much of the world.

Immunization helps in the prevention of disease. It is more easily and more cost-effective than treating it.
The benefits of immunization can be viewed as two sides of a coin
