title: [Combined vaccine against tetanus, diphtheria and polio. A randomized controlled study of immunogenicity and tolerance].
abstract: BACKGROUND, METHOD: Given the worldwide distribution of infection and the mobility of large parts of the population immunizations against tetanus, diphtheria and polio remain a challenge. This is especially true for adolescents and adults since antibodies tend to wane once immunized children enter adolescence and adulthood. A new combination vaccine against tetanus, diphtheria and polio (Td-IPV) for booster immunizations was subjected to a randomized, controlled and single-blind trial. Non-inferiority had to be demonstrated with regard to efficacy (immunogenicity) and safety in comparison to separate Td and IPV injections.
  
  
  RESULTS
  Almost 500 subjects from community practices and occupational/immunization clinics took part. Antibody titres were equivalent for all antigens. Local and systemic reactions were equal or even less marked in the intervention group.
  
  
  CONCLUSIONS
  From a public health perspective the new vaccine can make an important contribution to ensure adequate protection against tetanus, diphtheria and polio in adolescent and adult populations.
