USE OF THE PERTUSSIS AGGLUTINOGEN SKIN TEST IN A WELL BABY CLINIC
1 The A. Jacobi Division for Children of the Lenox Hill Hospital, New York City.
Intradermal skin tests with pertussis agglutinogen were performed on 234 infants.
In one group of 100 infants skin tested with this material, at least three months after pertussis prophylaxis, it was found that 92% had positive (immune) skin reactions.
In a second group of 134 infants skin tested prior to pertussis vaccination, 83% (111) had negative skin reactions. In 66 of these 111 infants tested after pertussis prophylaxis, 92% developed a positive skin response.
The pertussis skin agglutinogen test can be used to determine the efficiency of materials used for pertussis prophylaxis.
The pertussis skin agglutinogen test is a reliable indicator of the immune response of an infant to H. pertussis immunization and is recommended as an effective agent for determining the susceptible infantone lacking the minimal clinical protection against pertussisafter pertussis vaccination.
