<unk>  is a kind of health<unk>  that governments adopt in order to prevent the spread of infectious disease through vaccination. A wide variety of<unk> es have been developed over the approximately two centuries since the invention of vaccination with the purpose of creating herd immunity, or eradicating a disease altogether, for the population the government aims to protect. Vaccination advisory committees within each country are usually responsible for providing information to governments that is used to make evidence-based decisions regarding vaccine and immunization<unk> . Vaccinations are voluntary in some countries and mandatory in others, with mandatory<unk> es sometimes leading to opposition. Some governments pay for all or part of the costs of vaccinations in a national vaccination schedule. Cost-benefit analyses of vaccinations have shown that there is an economic incentive to implement<unk> es as vaccinations can save a significant number of lives and costs. Generally, vaccine supply is highly regulated by local government. Also, because of the large cost of developing a vaccine, the prices of vaccines are mostly high. Therefore, vaccine<unk>  is affected by regulations and competition.
