A sixth dose of tetanus, diphtheria, acellular pertussis (Tdap) vaccine in adolescents might
produce a differing reactogenicity and/or immunogenicity response depending on the …

235 healthy 10–12 years old school children were randomly immunized with either a
booster dose of diphtheria-tetanus-acellular pertussis (dTap) or diphtheria-tetanus (dT) …

Objective. To determine whether gender, race (black or white), or level of parental education
influenced serologic responses or reporting of clinical reactions after immunization with …

Background: Large injection site reactions commonly follow booster doses of diphtheria-
tetanus-acellular pertussis (DTaP) vaccines at 4–6 years of age. A vaccine with lower …

Concerns about the safety of whole-cell pertussis vaccines prompted development of
acellular vaccines that are less likely to provoke adverse events because they contain …

The objective of this open study was to monitor the long-term effectiveness of the Lederle-
Takeda diphtheria and tetanus toxoids and acellular pertussis antigen (s)(DTaP) vaccine …

Extensive efforts on the part of the National Institutes of Health (NIH), vaccine manufacturers,
and other investigators in the United States and Europe have generated important new …

Objective. To evaluate the immunogenicity and reactogenicity of an acellular pertussis
vaccine (pa) either formulated with diphtheria and tetanus toxoids (dTpa) or administered …

Objectives: The primary objective was to assess the nature and incidence of adverse events
after a fourth dose of a tricomponent acellular pertussis-diphtheria-tetanus vaccine given in …

Background. Diphtheria and tetanus toxoid combined with acellular pertussis (DTaP)
vaccines are less reactogenic than diphtheria and tetanus toxoid combined with whole cell …
