background: hepatitis b virus (hbv) fails to produce appropriate immune responses in some healthy individuals; thus, different strategies have been adopted to promote immune responses. the current study aimed at evaluating the efficacy of hbv vaccine coadministered with tetanus-diphtheria (td) vaccine compared with hbv vaccine in healthy individuals through measuring hepatitis b surface antibod...

In Hyderabad, India, diphtheria is common among children aged 5-19 years. On account of low coverage of diphtheria vaccine boosters recommended under the universal immunization programme, a large proportion of children were susceptible/partially immune against diphtheria and/or tetanus. We evaluated immunogenicity and safety of single dose of indigenously developed tetanus-diphtheria (Td) vacci...

This study was conducted to evaluate the immunogenicity and safety of diphtheria-tetanus (Td) vaccine in adults over 40 yr old who had never received a diphtheria-tetanus-pertussis (DTP) vaccination. A total of 242 subject completed three-doses of Td vaccination and subsequent assays for immunogenicity. Before vaccination, 33.9% and 96.7% participants showed antibody levels of diphtheria and te...

CONTEXT Increasing reports of pertussis among US adolescents, adults, and their infant contacts have stimulated vaccine development for older age groups. OBJECTIVE To assess the immunogenicity and reactogenicity of a tetanus-diphtheria 5-component (pertussis toxoid, filamentous hemagglutinin, pertactin, and fimbriae types 2 and 3) acellular pertussis vaccine (Tdap) in adolescents and adults. ...

Rise of diphtheria cases in adults is a cause of concern worldwide. Pertussis is also now affecting adults. We assessed serum levels of tetanus, diphtheria and pertussis antibodies in 62 adults in Pune, India, who had missed their primary immunization. All adults were then given three doses of tetanus-diphtheria (Td) vaccine at 0, 1, and 6 months. All adults were immune to tetanus but 78% had l...

In 2005, two tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccines were licensed and recommended for use in adults and adolescents in the United States: ADACEL (sanofi pasteur, Swiftwater, Pennsylvania), which is licensed for use in persons aged 11--64 years, and BOOSTRIX (GlaxoSmithKline Biologicals, Rixensart, Belgium), which is licensed for use in persons aged 10...

BACKGROUND Local reactions are the most commonly reported adverse events following tetanus and diphtheria toxoid (Td) vaccine and the risk of local reactions may increase with number of prior Td vaccinations. METHODS To estimate the risk of medically attended local reactions following Td vaccination in adolescents and young adults we conducted a six-year retrospective cohort study assessing 4...

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...

background: antibody production in patients with end-stage kidney disease impairs due to several mechanisms. there are different ways to improve response rate to hepatitis b (hb) vaccine. in this study we evaluated the effect of tetanus-diphtheria toxoid (td) vaccine on hbs antibody (ab) level while being given simultaneously with hb vaccine.  methods: we recruited 43 hemodialysis and 20 perito...
