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 ...

Administration of diphtheria and tetanus toxoids and pertussis vaccine adsorbed (DTP vaccine) or endotoxin (LPS) resulted in marked alterations in hepatic drug-metabolizing enzymes in endotoxin-responsive (R) and non-endotoxin-responsive (NR) mice. A single human dose (0.5 ml) of DTP vaccine increased hexobarbital-induced sleep times to 1.6- to 1.8-fold above those of controls in both strains o...

Introduction Autoimmune diseases have been linked to COVID-19 vaccines. An increasing number of cases reported de novo immune thrombocytopenia (ITP) following mRNA This study aims investigate the incidence ITP vaccine in comparison other non-mRNA vaccines and COVID-19. Methods Data were collected from TriNetX global health research network, which covers over 117 million patients. Four different...

Evidence-based guidelines for immunization of infants, children, adolescents, and adults have been prepared by an Expert Panel of the Infectious Diseases Society of America (IDSA). These updated guidelines replace the previous immunization guidelines published in 2002. These guidelines are prepared for health care professionals who care for either immunocompetent or immunocompromised people of ...

OBJECTIVE Data on the effectiveness of the diphtheria-tetanus-acellular pertussis (DTaP) vaccine in the first 4 years of life are sparse. We evaluated the vaccine effectiveness (VE) of 1 and 2 doses of DTaP before 6 months of age and of 3 doses from 6 months of age in Australia, where, since 2003, a fourth dose is not given until 4 years. METHODS We matched reported pertussis cases aged 2 to ...

BACKGROUND The number of cases of pertussis reported has increased gradually in the last decade. Pertussis vaccination is the most effective strategy for the prevention of infection. Despite the fact that young infants are at the highest risk for pertussis, the rate of tetanus-diphtheria-acellular pertussis (Tdap) vaccination is presumed to be very low among women of childbearing age in Korea. ...

We conducted a prospective study to compare the development of fever (axillary T ≥ 37.9 °C) within 4 hours of vaccination, determine the proportion of children who develop high fever (T ≥ 39°C) and evaluate parental days missed from work due to their children's vaccination with either the diphtheria-tetanus-whole cell pertussis (DTwP) or diphtheria-tetanus-acellular pertussis (DTaP) vaccine. Th...

introduction the extended program of immunization (epi) in iran is started in 1984, and it played an important and effective role in controlling many infectious diseases in community. the objective of this study was to determine the time trends of vaccination coverage by the type of vaccine among children, in the age group of 0-24 months, in iran from the beginning of epi (1984) to 2013. materi...

We evaluated the immunogenicity and reactogenicity of diphtheria, tetanus, whole-cell pertussis and hepatitis B (DTPw-HB) combination vaccine manufactured by Shantha Biotechnics Pvt Ltd, Hyderabad, India in healthy infants between 6 and 8 weeks of age. Overall 123 infants (male:female ratio, 1:1.3) were recruited, of which 112 received all three doses of the vaccine at 6, 10 and 14 weeks of age...
