More than 20 genetically distinct BCG vaccine strains are in use worldwide. Previous studies suggest that BCG vaccine strain influences the immune response and protection against TB. Current data on which BCG vaccine strain induces the optimal immune response in humans are insufficient.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>To compare the immune response to three different BCG vaccine strains given to infants at birth.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Newborn infants in a tertiary women's hospital were immunized at birth with one of three BCG vaccine strains.

Of the 209 infants immunized, data from 164 infants were included in the final analysis (BCG-Denmark, n = 54; BCG-Japan, n = 54; BCG-Russia, n = 57). The proportion of polyfunctional CD4 T cells was significantly higher in infants immunized with BCG-Denmark (0.013%) or BCG-Japan (0.016%) than with BCG-Russia (0.007%) (P = 0.018 and P = 0.003, respectively). Infants immunized with BCG-Japan had higher concentrations of secreted Th1 cytokines; infants immunized with BCG-Denmark had higher proportions of CD107-expressing cytotoxic CD4 T cells.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>There are significant differences in the immune response induced by different BCG vaccine strains in newborn infants. Immunization with BCG-Denmark or BCG-Japan induced higher frequencies of mycobacterial-specific polyfunctional and cytotoxic T cells and higher concentrations of Th1 cytokines. These findings have potentially important implications for global antituberculosis immunization policies and future tuberculosis vaccine trials.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1164\/rccm.201104-0714oc","type":"journal-article","created":{"date-parts":[[2011,11,3]],"date-time":"2011-11-03T22:56:16Z","timestamp":1320360976000},"page":"213-222","source":"Crossref","is-referenced-by-count":130,"title":["The Influence of Bacille Calmette-Gu\u00e9rin Vaccine Strain on the Immune Response against Tuberculosis: A Randomized Trial"],"prefix":"10.1093","volume":"185","author":[{"given":"Nicole","family":"Ritz","sequence":"first","affiliation":[{"name":"Department of Paediatrics, The University of Melbourne, Parkville, Victoria, Australia"},{"name":"Murdoch Children's Research Institute, Parkville, Victoria, Australia"},{"name":"The Royal Children's Hospital Melbourne, Parkville, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Binita","family":"Dutta","sequence":"additional","affiliation":[{"name":"Murdoch Children's Research Institute, Parkville, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan","family":"Donath","sequence":"additional","affiliation":[{"name":"Department of Paediatrics, The University of Melbourne, Parkville, Victoria, Australia"},{"name":"Murdoch Children's Research Institute, Parkville, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Casalaz","sequence":"additional","affiliation":[{"name":"The Mercy Hospital for Women, Heidelberg, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tom G.","family":"Connell","sequence":"additional","affiliation":[{"name":"Department of Paediatrics, The University of Melbourne, Parkville, Victoria, Australia"},{"name":"Murdoch Children's Research Institute, Parkville, Victoria, Australia"},{"name":"The Royal Children's Hospital Melbourne, Parkville, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc","family":"Tebruegge","sequence":"additional","affiliation":[{"name":"Department of Paediatrics, The University of Melbourne, Parkville, Victoria, Australia"},{"name":"Murdoch Children's Research Institute, Parkville, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roy","family":"Robins-Browne","sequence":"additional","affiliation":[{"name":"Murdoch Children's Research Institute, Parkville, Victoria, Australia"},{"name":"Department of Microbiology and Immunology, The University of Melbourne, Parkville, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Willem A.","family":"Hanekom","sequence":"additional","affiliation":[{"name":"South African Tuberculosis Vaccine Initiative, Institute of Infectious Disease and Molecular Medicine and School of Child and Adolescent Health, University of Cape Town, Cape Town, South Africa;
