In Japan, mass vaccination for diphtheria, pertussis, and/or tetanus has been mandated by the Vaccination Law since 1948. In order to evaluate the efficacy of this vaccination policy, we conducted seroepidemiological studies on pertussis, diphtheria, and tetanus among individuals aged 0 - 80 years. The pertussis toxin seropositive rates of the vaccine-eligible groups and vaccine-ineligible grou...

Lichen planus is an inflammatory dermatosis with a prevalence of approximately 1%. Recent meta-analyses show that patients with hepatitis C virus have a 2.5- to 4.5-fold increased risk of developing lichen planus. Lichen planus has also followed vaccinations and has specifically been attributed to the hepatitis B vaccine, the influenza vaccine, and the tetanus-diphtheria-acellular pertussis vac...

OBJECTIVE To evaluate the safety of a combined diphtheria-tetanus-whole cell pertussis-Haemophilus influenzae type b vaccine used on the Brazilian National Immunizations Program, chiefly the incidence of hypotonic-hyporesponsive episodes. METHOD Follow-up of a cohort of 21,064 infants (20,925 or 99.7% adhered to the study protocol), within 48 hours of vaccination with diphtheria-tetanus-whole...

Serogroup B Neisseria meningitidis (MenB) is a major cause of invasive disease in early childhood worldwide. The only MenB vaccine available in Brazil was produced in Cuba and has shown unsatisfactory efficacy when used to immunize millions of children in Brazil. In the present study, we compared the specific functional antibody responses evoked by the Cuban MenB vaccine with a standard vaccine...

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....

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...

Whooping cough and diphtheria are vaccine preventable diseases. Diphtheria, due to Corynebacterium diphtheriae or Corynebactium ulcerans, two Gram positive bacteria, is a serious upper respiratory tract disease with high morbidity and mortality rates. Vaccination, via an acellular vaccine composed only of purified, detoxified diphtheria toxin, has significantly reduced the incidence of the dise...

Recombinant cholera toxin B subunit (rCTB) which is produced by Bacillus brevis carrying pNU212-CTB acts as a mucosal adjuvant capable of enhancing host immune responses specific to unrelated, mucosally co-administered vaccine antigens. When mice were administered intranasally with diphtheria-pertussis-tetanus (DPT) combination vaccine consisting of diphtheria toxoid (DTd), tetanus toxoid (TTd)...

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...
