On February 12, 2009, the US Court of Federal Claims issued a trio of long-awaited decisions in its Omnibus Autism Proceeding.1 The 3 were representative cases chosen from more than 5500 pending MMR/autism cases by the Plaintiffs’ Steering Committee. Each presented the theory that the measles-mumps-rubella (MMR) vaccine in combination with thimerosal, a mercury-based ingredient contained in som...

BACKGROUND Vaccination against pertussis during pregnancy is recommended to protect newborns, yet there is limited information about the effectiveness of maternal tetanus toxoid, reduced diphtheria toxoid, acellular pertussis (Tdap) vaccine before the first infant dose of diphtheria, tetanus and acellular pertussis (DTaP) vaccine and during the first year of life in infants who have received DT...

Antibody production in mice after immunization with diphtheria-pertussis-tetanus (DPT) vaccine was investigated. Six lots of the vaccine produced in the same year by six manufacturers in Japan were chosen. Production of IgE antibody specific to either diphtheria or tetanus toxoid varied among vaccine preparations used, although there was no apparent difference in IgG antibody production after i...

Introduction Pertussis is re-emerging worldwide, despite effective immunization programs for infants and children. Epidemiological studies show a more limited duration of protection against clinical pertussis in adolescents primed with acellular pertussis (aP) vaccines during infancy than those who have been primed with whole-cell pertussis (wP) vaccines. This study aimed to determine whether m...

BACKGROUND Thimerosal is an ethylmercury-containing compound (49.6% mercury by weight) used as at the preservative level in vaccines (0.005% to 0.01%). METHODS Statistical modeling in a meta-analysis epidemiological assessment of the Vaccine Adverse Event Reporting System (VAERS) for neurodevelopment disorders (NDs) reported following Diphtheria-Tetanus-whole-cell-Pertussis (DTP) vaccines in ...

OBJECTIVE To evaluate the literature examining prophylactic use of acetaminophen and ibuprofen for prevention of adverse reactions associated with childhood immunization. DATA SOURCES Articles were identified via MEDLINE/PubMed/EMBASE (1966-March 2007) using the following key terms: vaccination, immunization, diphtheria-tetanus toxoids-whole pertussis (DTwP), diphtheria tetanus-toxoid, whole ...

Anti-N-methyl-d-aspartate (Anti-NMDA) receptor encephalitis is an acute autoimmune neurological disorder. The cause of this disease is often unknown, and previous studies revealed that it might be caused by a virus, vaccine or tumor. It occurs more often in females than in males. Several cases were reported to be related to vaccination such as the H1N1 vaccine and tetanus/diphtheria/pertussis a...

BACKGROUND Because of concern about safety and efficacy, no pertussis vaccine has been included in the vaccination program in Sweden since 1979. To provide data that might permit the reintroduction of a pertussis vaccine, we conducted a placebo-controlled trial of two acellular and one whole-cell pertussis vaccines. METHODS After informed consent was obtained, 9829 children born in 1992 were ...

Background: After substitution of Pentavalent vaccine with diphtheria, tetanus, pertussis (DTP) in the Iranian National Vaccination program with 3 Pentavalent (three times vaccination with Pentavalent vaccine at months 2, 4, and 6) in 2014 and the lack of published research in the field of immunogenicity of pertussis component of this vaccine, the efficacy of pertussis vaccine was studied 6 mon...
