Currently, there are three Hib conjugate vaccines licensed in Canada for use in infants 2 months of age and older. The Bureau of Biologics recently approved two new vaccine products that allow single-needle administration of (a) polyribose ribitol phosphate-tetanus toxoid (PRP-T) with diphtheria toxoid-pertussis vaccine-tetanus toxoid-inactivated poliovirus vaccine (DPT-IPV), and (b) oligosacch...

In October 2011, a child who had arrived in Sweden from Somalia presented with atypical tonsillitis, was treated with penicillin and the symptoms resolved. A throat swab was positive for toxigenic Corynebacterium diphtheriae. The child's family were then vaccinated with diphtheria, tetanus and pertussis vaccine and screened for C. diphtheriae. No secondary cases were found. A high level of adhe...

BACKGROUND Diphtheria and tetanus toxoid combined with acellular pertussis (DTaP) vaccines are less reactogenic than diphtheria and tetanus toxoid combined with whole cell pertussis (DTwP) vaccines. However, local reactions increase in rate and severity with each successive DTaP dose, and swelling of the entire injected limb has been reported after booster doses. METHODS We reviewed reports o...

Acellular vaccines against diphtheria-tetanus-pertussis (acellular pertussis) (DTaP) are being progressively introduced into vaccination programs worldwide, with the aim of reducing T-helper 1 (Th1)-associated reactogenicity associated with the cellular diphtheria-tetanus-pertussis (whole-cell pertussis) (DTwP) vaccine. The DTaP vaccine has an improved safety profile in infants, but little info...

Recommendations for routine vaccinations in children and adolescents have changed multiple times in recent years, based on findings in clinical trials, licensure of new vaccines, and evidence of waning immunity. Despite the overwhelming success of vaccinations, vaccine delay and refusal are leading to pockets of vaccine-preventable diseases. Schedules for diphtheria and tetanus toxoids, and ace...

On July 11, 2016, state and local health departments in Kentucky were notified of a case of obstetric tetanus in an unvaccinated woman. Obstetric tetanus, which occurs during pregnancy or within 6 weeks of the end of pregnancy, follows contamination of wounds with Clostridium tetani spores during pregnancy, or the use of contaminated tools or practices during nonsterile deliveries or abortions....

AIMS To describe the immune response of preterm infants to combined diphtheria/tetanus/5 component acellular pertussis-Haemophilus influenzae type b inactivated polio vaccine (DT5aP-Hib-IPV) and meningococcal serogroup C conjugate vaccine (MCC) under accelerated schedule. To compare results with term infants immunised with DT5aP-Hib-IPV and with historical data from preterm infants immunised wi...

Background and Objectives: HIV infected patients are at risk for vaccine-preventable infections such as tetanus and diphtheria (Td). In these patients, these antibodies tend to decline faster. Due to the limited data, this study assessed the seroprevalence of tetanus and diphtheria antibodies in HIV infected patients in Tehran, Iran. Materials and Methods: This case-control study was carried o...
