This boy, age 13, brother of Ruth Minnick, was vaccinated from same capsule as sister who died; was very sick with symptoms “about like the girl,” but recovered with no serious consequences. It appears almost certain that this was what may be called an “abortive” or “arrested” case of infantile paralysis. The fact that he was vaccinated simultaneously with his sister, who died of a transparent case of infantile paralysis, is strong presumptive evidence of a common origin of the two cases in the vaccine. Cumulative evidence of this common origin in the virus, and of the possibility of transmitting infantile paralysis by means of the vaccine abrasion, is found in a _third case in the same house_, as follows: CASE No. 29 CHARLES S. MINNICK, son of S. V. Minnick, Carthage, N. Y. Age 6. Vaccinated Oct. 6. Commenced to complain Oct. 16,--10 days from vaccination. Recovered. Diagnosis, “Vaccination.” The first unfavorable symptom was kidney trouble. He was _unconscious and helpless for two weeks_. Breathing labored. Is recovering slightly crippled. This also seems to be a transparent case of infantile paralysis. These three cases in the same house, with identical symptoms, following vaccination in exactly the same period of time, furnish the most damaging evidence against vaccine that has been brought to light in the present investigation. MR. LOYSTER’S ARGUMENT AND PROOF THAT INFANTILE PARALYSIS IS CAUSED BY VACCINATION The theory of the possibility of conveying infantile paralysis through vaccine abrasions as well as the probability of the vaccine having contained the germs receives startling confirmation in three cases in the home of S. V. Minnick of Carthage, reported under numbers 27, 28, and 29. Ruth, 10½, and Hobart, 13, were vaccinated the same day _from the same tube of virus_. Both became very sick in just ten days from vaccination. The boy, being older, recovered, after a severe illness, with symptoms much like the girl. Ruth died after a plain case of infantile paralysis, which was so reported by her attending physician. Four days before the little girl’s death, in compliance with the demand of the school authorities, the little brother, Charles, age 6, was vaccinated. In precisely 10 days he, also, became very sick, with symptoms practically identical with the other two children. He was _unconscious and helpless_ for two weeks, but recovered with a slight residual paralysis. He was attended by another physician and the only diagnosis reported is “vaccination.” Simultaneous cases of infantile paralysis in the same family have hitherto been so rare as to excite comment. Many physicians with large practice have never had an instance in their entire practice. Here are _three_ in one house.
