Purpose and Benefits of Annual Flu Vaccination

The concept of herd immunity is the foundation for all vaccinations. Herd immunity can be defined as immunity in a significant portion of a population, usually at least 80 percent, to a given disease. Whether they are immune because they have been vaccinated or because they have already encountered the illness and built their own natural immunity, they provide protection to others who are not immune because the illness has little chance of spreading in the population.

    It is too late in the century for women who have received the benefits of co-education in schools and colleges, and who bear their full share in the world’s work, not to care who make the laws, who expound and who administer them.
    J. Ellen Foster (1840–1910)

    No annual training or muster of soldiery, no celebration with its scarfs and banners, could import into the town a hundredth part of the annual splendor of our October. We have only to set the trees, or let them stand, and Nature will find the colored drapery,—flags of all her nations, some of whose private signals hardly the botanist can read,—while we walk under the triumphal arches of the elms.
