Combined pertussis-diphtheria prophylactic antigens: An experimental study to determine the specific immunizing value of these antigens used in combination
Published online by Cambridge University Press: 15 May 2009
Extract
1. Experiments in laboratory animals are described, which were made to determine the specific antibody production following injections of diphtheria and pertussis antigens separately or in combination.
2. Agglutinins to H. pertussis vaccine were not increased or otherwise changed by combining H. pertussis vaccines with either diphtheria anatoxine or A.P.T.
3. A striking enhancement of diphtheria antitoxin production occurred when diphtheria prophylactics were used combined with pertussis vaccine. Such improvement in antitoxin production was most marked in the case of diphtheria anatoxine, but was also shown following the use of A.P.T. in combination with pertussis vaccine.
4. Diphtheria anatoxine combined with H. pertussis vaccine gave no better antitoxin response than did a.p.t. alone.
