Viil] AND SMALLPOX 63 the breast who were entirely free from the disease. The mother, when apart from the infant, had been exposed to infection and taken it, and had gone on nursing her infant until the rash of smallpox came out. Although these infants were then exposed to infection with extreme thoroughness, and it would seem inevitable for them to take smallpox, in point of fact a number of them never took it. Those who did not take it, differed from those who did, in having been successfully... vaccinated within three days of exposure to infection. Questions may often arise about the necessity of renewing and bringing vaccination up to date. The fact is that protection conferred by vaccina- tion wears out after a lapse of time which is uncertain and varies with each individual. No one can say, for any given individual, what the length of that lapse of time may be. Re- vaccination may be effective for a period of 20 years. Primary vaccination does not confer immunity for so long a period as this.
