In Japan, the morbidity rate for pertussis per 100,000 population was 147.6 in 1950 when whole cell pertussis vaccine was introduced but dropped to 0.2 in 1972 when routine immunization with a combined vaccine consisting of diphtheria toxoid, tetanus toxoid, and whole cell pertussis had been widely accepted. Thereafter, adverse reactions to the whole cell pertussis vaccine became a social probl...

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...

PURPOSE Active reduced dose tetanus-diphtheria-acellular pertussis (Tdap) vaccination for adolescents and adults is necessary because waning immunity after primary diphtheria-tetanus-pertussis vaccination is related to the recent emergence of pertussis. This study was conducted to compare the immunogenicity and protection efficacy against Bordetella pertussis between a new GCC Tdap vaccine and ...

To determine if inactivated poliovirus vaccine combined with diphtheria and tetanus toxoids and whole-cell pertussis vaccine interferes with the immunogenicity of pertussis vaccine, we performed a randomized trial of diphtheria and tetanus toxoids and pertussis vaccine combined with inactivated poliovirus vaccine given as a single injection or as two separate injections at the same visit to inf...

Vietnam plans to replace the routine childhood diphtheria, pertussis and tetanus combination (DPT) vaccine with a pentavalent vaccine. The present study was performed to assess the immunogenicity and safety of the combined diphtheria, tetanus, whole-cell pertussis, hepatitis B (HepB), and Haemophilus influenzae type b (Hib) (DTwP-HepB-Hib) Quinvaxem® vaccine in children. A total of 131 infants ...

sised the capacity of the immune system to respond effectively to numerous simultaneous antigens. Using data linkage, Miller et al found no evidence for an increase in admissions to hospital for serious bacterial infections following MMR vaccination. 9 One disadvantage of giving vaccines in combination is that it may not always be clear which component is responsible for a particular adverse ev...

Transplacentally transferred antibodies induced by maternal pertussis vaccination interfere with infant immune responses to primary vaccination. We evaluated whether this interference remains in toddlers after booster In a prior phase IV, observer-blind, placebo-controlled, randomized study (NCT02377349), pregnant women Australia, Canada and Europe received intramuscular tetanus-reduced-antigen...

background: immunization against diphtheria, tetanus and pertussis (dtp) has long been applied in iran using whole cell vac­cine. despite the role of whole cell dtp (dtwp) vaccine in reduction of mortality as a result of disastrous diseases such as diphtheria, tetanus, and pertussis, serious local and systemic complications have been attributed to these vaccines. this study was performed to det...

INTRODUCTION In England, antenatal pertussis immunization using a tetanus/low-dose diphtheria/5-component acellular-pertussis/inactivated-polio (TdaP5/IPV) vaccine was introduced in October 2012. We assessed infant responses to antigens in the maternal vaccine and to those conjugated to tetanus (TT) or the diphtheria toxin variant, CRM. METHODS Infants of 141 TdaP5/IPV-vaccinated mothers in S...

Vaccination prevents around 2–3 million deaths worldwide every year from infectious diseases such as diphtheria, tetanus, pertussis, influenza and measles​[1]​. Despite the efficacy of vaccines, vaccine hesitancy — belief that a may be unnecessary, ineffective or unsafe is common (reported in more than 90 countries, at all income levels), growing to […]
