An Estimate of the True Value of Vaccination as a Security Against Small Pox

The pamphlet compiles and condenses the principal facts and medical evidence supporting vaccination as protection against smallpox, presenting that information in accessible form to address public doubts and prejudices. It reviews professional writings, acknowledges reported instances that have shaken confidence, and argues that the overall evidence indicates substantial protective benefit when vaccination is widely applied. It stresses the need for general cooperation, urging informed and influential members of society to persuade others — particularly among the poor — to have infants vaccinated, and it recommends public education and coordinated effort to extend vaccination’s benefits.
