摘要

What good is vaccination? Obviously it is good for the person receiving the vaccine, if he is thus prevented from suffering from a nasty disease. More subtly, it can be good for an entire population since, if enough of its members are vaccinated, even those who are not will receive a measure of protection. That is because, with only a few susceptible individuals, the transmission of the infection cannot be maintained and the disease spread. But in the case of many vaccines, there are non-medical benefits, too, in the form of costs avoided and the generation of income that would otherwise have been lost. These goods are economic.
