Vaccination is the administration of antigenic material (a vaccine) to stimulate an individual's immune system to develop adaptive immunity to a pathogen. Vaccines can prevent or ameliorate morbidity from infection. When a sufficiently large percentage of a population has been vaccinated, this results in herd immunity. The effectiveness of vaccination has been widely studied and verified; for example, the influenza vaccine, the HPV vaccine, and the chicken pox vaccine.

A business strategy is the means by which it sets out to achieve its desired ends (objectives). It can simply be described as a long-term business planning. Typically a business strategy will cover a period of about 3-5 years (sometimes even longer). A business strategy is concerned with major resource issues e.g. raising the finance to build a new factory or plant. Strategies are also concerned with deciding on what products to allocate major resources to - for example when Coca-Cola launched Pooh Roo Juice in this country.
