The purpose of this study is to evaluate the safety of Adacel vaccine among pregnant individuals exposed to Adacel at any point between the 1st day of the 27th week of gestation up to the end of pregnancy and their offspring (ie, Adacel-exposed cohort), in comparison with pregnant individuals not vaccinated with any Tdap vaccines during pregnancy and their offspring (ie, Tdap-unvaccinated comparator cohort). The primary objectives are to estimate incidence rates and relative risks for each prespecified pregnancy outcome in Adacel-exposed and Tdap-unvaccinated comparator cohorts and for each prespecified adverse birth outcome in the offspring of both cohorts. The secondary objectives are to estimate incidence rates and relative risks for each prespecified adverse fetal and neonatal outcome in the offspring of Adacel-exposed and Tdap unvaccinated comparator cohorts and for each prespecified adverse outcome for pregnant individuals in both cohorts.
This study is a randomized, blinded, active-controlled phase I clinical trial to evaluate the safety and preliminary immunogenicity of the Diphtheria-Tetanus-acellular Pertussis Component Combined Vaccine (DTacP) in subjects (aged 2 months to 6 years). Primary safety endpoints are the occurrence of solicited adverse events within 30 minutes after each dose, the occurrence of solicited adverse events within 7 days after each dose, the occurrence of unsolicited adverse events within 30 days after each dose, and the occurrence of adverse events 30 days after immunization. The secondary safety endpoint is the occurrence of serious adverse events (SAEs) within 12 months after immunization. Secondary immunogenicity endpoints are the geometric mean concentration (GMC), geometric mean fold increase (GMFI), seropositive rates, seroconversion rates, or 4-fold increase rates of anti-DT, anti-TT, anti-PT, anti-FHA, and anti-PRN antibodies 30 days after immunization. The exploratory endpoints are the GMC, GMFI, seropositive rates, seroconversion rates, or 4-fold increase rates of anti-DT, anti-PT, and anti-FHA neutralizing antibodies 30 days after immunization in all groups, the GMC and seropositive rates of anti-DT, anti-TT, anti-PT, anti-FHA, and anti-PRN antibodies 12 months after primary immunization in the infant group, the seropositive rates and geometric mean tie (GMT) of anti- type I, type II, type III poliovirus neutralizing antibodies 30 days after immunization in all groups, the seropositive rates and geometric mean tie (GMT) of anti- type I, type II, type III poliovirus neutralizing antibodies 12 months after primary immunization in the infant group.
The goal of this randomized control trial is to assess if prenatal vaccine education and in-office vaccination administration for non-birthing partners of pregnant patients increases Tdap vaccination rates compared to usual care. The main question[s] it aims to answer are: - To assess whether compared to standard prenatal care, targeted prenatal education regarding Tdap vaccination recommendations with and without in office vaccination opportunities improves Tdap uptake among non-birthing partners of pregnant patients. - To assess whether non-birthing partners presenting for Tdap vaccination are willing to accept dual vaccination with Tdap and influenza. Participants will receive direct verbal and written education at the time of enrollment on cocooning and recommendation for partner Tdap vaccination prior to delivery with or without the option to receive Tdap at their convenience at the WIH obstetric care clinic. If there is a comparison group: Researchers will compare "Upfront Education" and "Upfront Education and Vaccination Administration" to "Usual care" to see if education and/or the offer for vaccination in the office increases Tdap vaccine acceptance for non-birthing partners.
Pertussis is an acute respiratory infectious disease caused by Bordetella pertussis, diphtheria is an acute upper respiratory infectious disease caused by Gram-positive Corynebacterium diphtheriae, and tetanus is a highly fatal disease caused by Clostridium tetani infection. Currently, there is no clinical trial registration of Diphtheria, tetanus, and pertussis (DPT) vaccine applicable to ≥6 years of age in China, therefore, the five-component acellular DPT combination vaccine developed by our research has a promising future.
The aim of this study is to evaluate the safety profile of Diphtheria Antitoxin
This is a single-center, randomized, active-controlled, parallel-design, double-blind, phase I study to evaluate the safety and immunogenicity of a single dose of APV006 in healthy adults.
The combined pertussis, diphtheria and tetanus vaccine, the first vaccine to be included in the Expanded Programme of Immunization(EPI) of World Health Organization(WHO), has played an important role in the prevention and control of these three infectious diseases. The (diphtheria，tetanus and acellular pertussis combined vaccine，DTaP) vaccine was successfully developed in China in 1993, and its safety and serological effects were confirmed by the observation of human safety, with mild vaccination reactions and good immunization effects.The (Diphtheria-tetanus-component acellular pertussis vaccine, DTcP) vaccine is suitable for immunization against pertussis, diphtheria and tetanus infections in people between 2 and 24 months of age.
Toxigenic cutaneous diphtheria is a notifiable disease that is re-emerging in the world and particularly in France. A better description of the epidemiological characteristics, as well as a refinement of the clinical characteristics of patients with cutaneous diphtheria, are essential to better understand this pathology, which has important public health issues and whose diagnosis absence can have catastrophic consequences for the patient and their contacts. Microbiological data (species identification, toxigenicity or not, resistance profile...) will be transmitted by the national reference center for corynebacteria of the diphtheriae complex and then caregivers who have managed the corresponding patients with cutaneous diphtheria will be contacted.
This is an open-label Phase Ia/Ib clinical study of tagraxofusp-erzs, a novel cytokine-drug conjugate that links interleukin-3 with a truncated diphtheria toxin, in combination with gemtuzumab ozogamicin for patients with relapsed/refractory AML. The primary objective of the study is to determine the recommended phase 2 dose (RP2D) of tagraxofusp-erzs in combination with gemtuzumab ozogamicin in this patient population. Then, once RP2D is determined, to determine the safety and tolerability of combination gemtuzumab and tagraxofusp-erzs when administered at the RP2D.
