Reduced-antigen-content pertussis vaccines designed initially for booster vaccination of adolescents and adults can also be used to vaccinate pre-school age children. Combination vaccines, which reduce the number of administered injections, combine multiple antigens including inactivated poliovirus (IPV), which is recommended in this age group in some(More)
German adolescents (n=123) without previous pertussis vaccination, no history of pertussis and low IgG-anti-pertussis-toxin (PT) levels received one dose of the Tdap vaccine Boostrix. Blood samples were taken before, and 5-12 days and 29-49 days after vaccination. IgG- and IgA-anti-PT, IgG- and IgA-anti filamentous hemagglutinin, IgG-anti-pertactin,(More)
Booster vaccination with a reduced-antigen-content dTpa, pediatric DTPa or adult Td vaccine in DTPa-primed children aged 4-6 years was evaluated. Immunogenicity and CMI was assessed one month and 3.5 years after vaccination. Symptoms were solicited for 15 days post-vaccination. There were no differences between groups in diphtheria or tetanus seroprotection(More)
High rates of pertussis disease in adolescents suggest that additional boosting against pertussis would be beneficial. A combined acellular-pertussis-containing booster vaccine (dTpa-IPV; Boostrix™ Polio, n =440) was compared to separately administered dTpa (Boostrix™) and inactivated polio virus (IPV; Imovax Polio®, n =219), and to DTPa-IPV (Infanrix™ IPV,(More)
Many countries recommend diphtheria, tetanus and/or poliomyelitis boosters in adolescents or adults and the need for pertussis booster vaccination beyond childhood is increasingly recognized. A new combined reduced-antigen-content dTpa-IPV vaccine provides booster vaccination against all four diseases in one single injection. The immunogenicity and safety(More)
The reduced antigen content diphtheria, tetanus and pertussis (dTpa) vaccine (Boostrixtrade mark) has been shown to induce a strong booster response to all the vaccine components in 4-6 year olds. However, anti-diphtheria antibody levels were observed to be lower when compared to the "full strength" paediatric DTPa vaccine. To assess the impact of this(More)
BACKGROUND We conducted a 5-year follow-up study on the persistence of pertussis-specific antibody and cell-mediated immunity after booster immunization of adolescents aged 11-13 years with a tricomponent acellular pertussis vaccine (Boostrix; trials diphtheria-tetanus-acellular pertussis [Tdap]-004/030). METHODS Cellular and humoral immunity to pertussis(More)
We evaluated pertussis-specific cell-mediated immunity (CMI) and humoral immunity in adolescents 3 years after they received an acellular pertussis booster immunization. Two hundred sixty-four adolescents were examined for immunoglobulin G antibodies, and 49 were examined for CMI against Bordetella pertussis antigens 40 months after receiving the booster. A(More)
In this study, we set out to determine if home intravenous (i.v.) antibiotic therapy in adult patients with cystic fibrosis (CF) is a feasible, effective and less costly alternative to hospitalization, and to assess the impact of home therapy on quality of life. The study was a prospective, randomized, two-factor mixed design involving adults presenting(More)
OBJECTIVES Because young infants are at highest risk of pertussis complications, this study assessed whether neonatal acellular pertussis (aP) vaccination could provide earlier immunity. STUDY DESIGN Neonates (n = 121) were randomly assigned (1:1) to receive either aP or hepatitis B vaccine (HBV) (controls) vaccine at birth, followed by vaccination with(More)
