A Short Guide on how Vaccines Work
What is a Vaccine?
It is a product that stimulates a person's immune system to produce immunity to a specific disease, protecting the person from that disease. Vaccines are usually administered through needle injections, but can also be administered by mouth or sprayed into the nose.
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. The effectiveness of vaccination has been widely studied and verified for example, vaccines that have proven effective include the Influenza Vaccineand the Chicken Pox Vaccine. The World Health Organization (WHO) reports that licensed vaccines are currently available for twenty-five different preventable infections.
