This study is designed to allow cord blood sample collection from the cords of babies born in three gestational age windows: ≥37 gestational weeks, 32-36+6 gestational weeks and less than 32 gestational weeks to investigate whether the result obtained using a standard hSBA assay is comparable to that achieved using complement from a gestation matched population for meningococcal B and pertussis.

Seroimmunity 2007 and Sub Study of the Swedish Population Regarding Vaccine Preventable Disease...

DiphtheriaTetanus7 more

This is a randomized cross-sectional study of the Swedish population. Blood samples will be collected from a subpopulation in order to estimate the age specific sero-prevalence of the Swedish population for diseases included in the National Immunization Program (NIP), and to affirm the population's protection against polio. To be able to recommend complementary immunizations to immigrated children, a sub study focusing on foreign born teenagers will also be done and compared to children of the same age born in Sweden.

Pathogenic Bordetella Rapid Detection

Pertussis

A CPA platform based on the CRISPR technology is going to established to achieve the goal of detecting pathogenic bordetella and drug resistance genes in one step. The accuracy of this platform will be checked through prospective diagnostic test evaluation methods. Bordetella pertussis isolation culture and identification would be set as a gold standard method.

Bordetella Pertussis Carriage in College-aged Students

Carriage of Bordetella Pertussis

The objective in this observational cohort study of young adults sampled at three intervals during the academic year is to ascertain if there is carriage of B. pertussis in asymptomatic individuals. We hypothesize that in asymptomatic college students there is no carriage of B. pertussis detectable by polymerase chain reaction (PCR) assay.

Seroprevalence of Pertussis Among Healthy Children and Adolescents in Kazakhstan

Pertussis

Seroprevalence of pertussis among older children and adolescents in Kazakhstan: A cross sectional study. Justification: to describe the distribution of anti-pertussis toxin (PT) antibodies (IgA and IgG) in a population aged 10-18 years old according to sociodemographic characteristics, vaccination history, and risk factors of pertussis infection.

Pertussis Immunization During Pregnancy: Effect in Term and Preterm Infants

Pertussis

Young infants are most vulnerable to severe disease and even death when infected with Bordetella Pertussis. The current vaccines and vaccination programs do not guarantee protection of neonates. During the last weeks of pregnancy, maternal IgG antibodies are transferred actively to the fetus. Administration of a pertussis containing vaccine during pregnancy offers protection through high titers of maternal antibodies transferred to the child. Since transplacental transport is immature, infants who are born prior to 37 weeks of gestation, might be vulnerable to pertussis infection even though maternal vaccination was administered, but specific data are lacking. The primary aim of this observational study is to measure whether vaccination during pregnancy offers protection to preterm born infants through higher titers of maternal antibodies, despite immature transplacental transport. Four cohorts of mother-infant pairs will be recruited: term versus preterm born infants, born from either vaccinated women or not vaccinated women. These mother-infant pairs are recruited according to the vaccination status of the mother and to the gestational age at delivery. Pertussis specific antibody titers (anti-Pertussis Toxin, anti-Filamentous haemagglutinin, anti-Pertactin titers) will be monitored in blood samples of the mothers at delivery to measure the possible influence of both gestational age and maternal vaccination status. In order to measure the decline of maternal antibodies in the first weeks of life, blood will be taken from cords as well as from infants at 8 weeks of age, before the first infant pertussis vaccine is administered. Pertussis antibodies to the same antigens will be measured in all infants after a primary series of acellular pertussis vaccines administered at 8,12 and 16 weeks of age and before and after a booster dose in the second year of life. In addition, cellular mediated immune responses will be evaluated in a subgroup of infants before and after a primary series of infants vaccines. A last goal is to measure whether vaccination during pregnancy could offer additional maternal antibodies through breast milk. Again a comparison is made between preterm and term born infants, born from either vaccinated or unvaccinated women. The amount of lactoferrin and pertussis toxin specific IgA in breast milk samples will be measured in samples taken at birth (colostrum), and at several time points afterwards as long as breastfeeding is continued.
