One of the most interesting facts brought out by the hospital cases, (Small-pox Hospital Blackwell's Island,) is the value of vaccination as a prevention. The vaccination of childhood is of no value unless repeated at intervals of three years. This is proved by the fact that All, or nearly all, of the cases have good pock marks. Again, the fact of having had the disease does not preclude the possibility of again taking it; and should not preclude the necessity of re-vaccination. It not unfrequently happens that a patient enters who is strongly pitted.—Quoted in Public Opinion, March 13th, 1875.
