Vaccines don't provide immunity from disease for some people. But if most people get vaccinated against a disease, such as measles, then the population achieves "herd immunity," which means that there are so few cases of the disease that even people for whom vaccinations are ineffective are unlikely to contract the disease. An article in the Economist magazine argues that, "herd immunity is a classic public good." This statement is A. not true, because not everyone can consume herd immunity whether or not they pay for it. B. true, because immunity is nonexcludable, and everyone can simultaneously enjoy the? "herd immunity." C. true, because a person receives some immunity from the disease by being vaccinated, even if other people are not vaccinated. D. not true, because immunity is nonexcludable, but in order for it to occur there must be a herd, and there is no guarantee that enough people will get vaccinated.

True or false? vaccination not only keeps the individual from contracting a disease but also makes it harder for the pathogen to find susceptible hosts.

Herd immunity only occurs in a population in which all individuals are immune. occurs in a population in which a large percentage of the population is immune. only provides protection to those that are already immune. is responsible for dramatic increases in childhood diseases. occurs in a population in which a large percentage of the population is immune AND is responsible for dramatic increases in childhood diseases.
