The plethora of newly discovered vaccines implies that, in the future, many vaccines will have to be administered simultaneously to infants. We examined the potential interference with the immune response of several coadministered vaccines containing the same protein component, namely, tetanus toxoid (TT). Infants simultaneously receiving a tetravalent pneumococcal vaccine conjugated to TT (Pnc...

Tetanus is caused by the tetanus neurotoxin (TeNT) and is one of the most dreaded diseases especially in the developing countries. The current vaccine against tetanus is based on an inactivated tetanus toxin, which is effective but has many drawbacks. In our previous study, we developed a recombinant tetanus vaccine based on protein TeNT-Hc, with clear advantages over the toxoid vaccine in term...

BACKGROUND  Maternal vaccination with an acellular pertussis (aP)-containing vaccine is a recommended strategy in a growing number of industrialized countries, to protect young infants from disease. Little is known on the effect of this strategy in low- and middle-income countries. Following a previous report on the effect of adding a pertussis and diphtheria component to the tetanus vaccinatio...

introduction: neonatal tetanus is a highly fatal disease that can be prevented by immunization and improvement in obstetric practices. the aim of the present study was to assess the characteristics of cases of neonatal tetanus in two large tertiary hospitals (ghaem and imam reza hospitals) of mashhad -north east of iran between 1984- 2001. methods: all cases whose epidemiological and clinical c...

BACKGROUND The low uptake of tetanus vaccine and its resultant high burden of tetanus in Nigeria suggest the need to improve routine and booster vaccination in children and adolescents. However, epidemiological evidence for vaccination in the adolescent age group needed for effective strategy and policy formulation is lacking. This study was carried out to determine the prevalence of protective...

STUDY OBJECTIVE We determine tetanus seroprotection rates and physician compliance with tetanus prophylaxis recommendations among patients presenting with wounds. METHODS A prospective observational study of patients aged 18 years or older who presented to 5 university-affiliated emergency departments (EDs) because of wounds was conducted between March 1999 and August 2000. Serum antitoxin le...

BACKGROUND Antibody against CD40 is effective in enhancing immune responses to vaccines when chemically conjugated to the vaccine antigen. Unfortunately the requirement for chemical conjugation presents some difficulties in vaccine production and quality control which are compounded when multivalent vaccines are required. We explore here an alternative to chemical conjugation, involving the co-...

The effect of abatacept, a selective T-cell co-stimulation modulator, on vaccination has not been previously investigated. In this open-label, single-dose, randomized, parallel-group, controlled study, the effect of a single 750 mg infusion of abatacept on the antibody response to the intramuscular tetanus toxoid vaccine (primarily a memory response to a T-cell-dependent peptide antigen) and th...
