Enclosed for your consideration for publication in BMC Pediatrics is the original manuscript, “An open-label randomized clinical trial in children of prophylactic paracetamol co-administered with 7-valent pneumococcal conjugate vaccine and hexavalent diphtheria toxoid, tetanus toxoid, 3-component acellular pertussis, hepatitis B, inactivated polio virus, and Haemophilus influenzae type b vaccine.”

Samples from 20 lots of diphtheria-tetanus (adult use dT) vaccine and from 20 lots of diphtheria-tetanus-pertussis (DTP) vaccine were used to standardize and validate the in vitro toxin binding inhibition (ToBI) test for the immunogenicity test of the tetanus component. The levels of tetanus antitoxin obtained by ToBI test were compared to those obtained using the toxin neutralization (TN) test...

The nature of antibody activities associated with purified immunoglobulin fractions of serum, secretions (whole saliva, parotid secretion, and intestinal secretion), and urine of a volunteer after subcutaneous booster injections with rabies virus, poliovirus, diphtheria and tetanus toxoids, and typhoid-paratyphoid-cholera vaccines was investigated. The results showed that the pattern of antibod...

BACKGROUND Pertussis occurs in older children, adolescents and adults due to waning immunity after primary vaccination. Booster vaccination for pre-school children has been recommended in Italy since 1999. In this study (NCT00871000), the immunogenicity, safety and reactogenicity of a booster dose of reduced-antigen content diphtheria-tetanus-acellular pertussis-inactivated poliovirus vaccine (...

This open, randomised controlled trial studied the immunogenicity and reactogenicity of two combined low-dose diphtheria, tetanus and acellular pertussis vaccines (Td5aP-IPV, REPEVAX, Aventis Pasteur MSD; and Td5aP, COVAXIS, Aventis Pasteur MSD + OPV, GlaxoSmithKline) in comparison with a standard dose diphtheria pre-school booster vaccine (DT2aP-IPV, TETRAVAC, Aventis Pasteur MSD) in a populat...

The diphtheria epidemic in eastern Europe and the worldwide increase in diphtheria morbidity have sparked discussion on whether people in western Europe are adequately protected. 2 In western Europe, the effectiveness of long term protection afforded by immunisation programmes is under debate. In Belgium, the national immunisation programme against diphtheria was introduced in 1959. Vaccination...

DPT, a combination vaccine against diphtheria, tetanus and pertussis is available since many years and still continued in the national immunisation schedule of many countries. Although highly potent, reactions to DPT vaccine are well known, mainly attributed to the factors like Pertussis component, aluminum adjuvant and lower purity of tetanus and diphtheria toxoids. The latter most important a...

OBJECTIVE To describe the immune response of preterm infants to a diphtheria/tetanus/three component acellular pertussis (DTaP) vaccine, under an accelerated schedule, and the effects of steroids on this response. To compare responses with those of term infants. DESIGN Prospective observational study. SETTING Five Wessex neonatal units; Hertfordshire immunisation clinics. PATIENTS Infants...

A GroEL-like protein from Bordetella pertussis was purified. This protein was found to have the tetradecameric subunit structure typical of the GroEL family of proteins and to contain epitopes similar to those of other members of this family, including a human GroEL-like protein. Active immunization of neonatal mice with the B. pertussis GroEL-like protein provided little protection against an ...
