Serums and Vaccines for the United States Army 



A Glimpse into the "Shop" 

 of the Laboratories 



This photograph shows the refrigerator in 

 the Bacteriological Laboratories of the 

 Department of Health of the City of New 

 York, where serums, vaccines and anti- 

 toxins are prepared for the use of the 

 United States Army. Much of this material 

 will be shipped to the front. In the con- 

 tainers and bottles which you see on the 

 shelves is $1 50,000 worth of material. 

 There is enough diphtheria antitoxin to 

 treat 75,000 men, enough tetanus antitoxin 

 for 200,000 men, enough smallpox vaccine 

 for a half million men, enough typhoid 

 fever vaccine for 25,000 men and enough 

 antimeningococcus serum to treat 2,500 

 men suffering from cerebrospinal meningitis 



Bleeding the Horse to Obtain 

 the Serum 



After the horse has been inoculated with 

 the disease poison in gradually increasing 

 doses he is bled and his serum is found 

 to be antitoxin. This is administered to 

 human beings and renders them immune 

 to the disease. The horses are kept in the 

 pink of condition. At periodic intervals 

 they are given a rest. During the rest 

 periods they are turned out to grass. When 

 thoroughly rested, they are inoculated 

 again. Some horses give more antitoxin 

 serum than others. The same horse may be 

 used at several different times for the prep- 

 aration of distinctly different antitoxins 



One of the 73 horses in 

 the stables of the De- 

 partment of Health of 

 the City of New York 

 at Ctisville. This horse 

 is being inoculated with 

 diphtheria toxin. Small 

 doses gradually in- 

 creased render the 

 horse immune to diph- 

 theria. Horses are used 

 in the preparation of 

 diphtheria, tetanus an- 

 titoxin and antimen- 

 ingococcus serum
