Most children's hospitals are quarantined for some time each year on account of measles. When the service is active and there are many cases of pneumonia, especially when a large percentage of the patients are infants, the necessity of using measles prophylaxis is paramount. During the past year the pediatric service of Mt. Sinai Hospital was quarantined four times, and we were thus able to observe the efficacy of convalescent serum supplied for us by the New York Board of Health. The supply of convalescent serum was not always adequate, so that a parent's whole or citrated blood or serum was used in several cases.
REVIEW OF LITERATURE
The first successful immunization against measles by means of convalescent serum was carried out by Nicolle and Conseil1 in 1916, and reported by them in 1918. Reports of numerous successful immunizations have appeared subsequently by Richardson and Connor,2 Degkwitz,3
