For rubella, where the vaccination insurance among moms differed by almost 50% however the difference in contact with natural infection will need to have been much less, we found no significant difference in the duration of protection by maternal antibodies. decay rate for maternal rubella antibodies was 7.01 per year (Supplementary Table 4); this corresponds to a half-life of about 1 month. The duration of protection against rubella was 3.9 months for newborns in the general population and those in the orthodox Protestant communities. Projection of the existing 1.1-fold difference between women of childbearing age onto a difference in duration of protection among infants revealed that infants in the general population would be guarded for 0.8 months less than infants in the orthodox Protestant communities. For varicella, no participants were GR 103691 vaccinated. The level of varicella antibodies did not differ between the 2 study groups. The decay rate for maternal varicella antibodies was 7.36 per year (Supplementary Table 4). The duration of protection against varicella was 3.4 months for newborns. We did not find differences between the maternal antibody level in infants at birth and those of women at childbearing age for any of the infections analyzed. The decay rate of antibodies in newborns did not differ between infants in the general populace and those in the orthodox Protestant community (Supplementary Table 4). Conversation In our analysis of maternal antibodies against measles, mumps, rubella, and varicella in a cross-sectional serologic study of the Dutch populace, we found that the average age at which infants lose protection lies well before 14 months, when the first dose of MMR vaccine is usually administered. We compared individuals sampled from the general populace with a group of individuals randomly selected from orthodox Protestant communities (the Dutch Bible belt), where the vaccination protection among mothers is much lower than that in the general populace. This comparison suggests that, as vaccination protection among mothers increases, the level of maternal antibodies at birth among infants and the duration of the protection afforded by maternal antibodies among newborns decrease. The most likely explanation for this is usually that MMR vaccine induces lower GR 103691 antibody levels than natural contamination with measles, mumps, and rubella and that antibody levels of vaccinated cohorts are no longer boosted by exposure to wild-type contamination. For measles, in which the vaccination protection among mothers differed by almost 40% between groups, we found that the period of maternal antibody protection among infants in the general populace was 2 months shorter than that among infants from orthodox Protestant communities. For rubella, in which the vaccination protection among mothers differed by almost 50% but the difference in exposure to natural infection must have been much less, we found no GR 103691 significant difference in the period of protection by maternal antibodies. However, if the significant difference between the adult women is usually carried onward to the infants, we observe that infants in the general populace were guarded for 0.8 month less by maternal antibodies than infants in orthodox Protestant communities. For both mumps, in which the vaccination protection among mothers differed by only 15% between groups, and varicella, we found no statistically significant difference in the period of protection by maternal antibodies. We assessed the duration of protection by maternal antibodies, using a cross-sectional study. The overall response was 33.5% (33% for the national sample and 35% for the low-immunization-coverage sample), which nowadays is relatively high for cross-sectional studies. Because of the large number of participants, we do not expect a self-selecting bias. Additionally, the advantage of this study design is usually that we have a large number of individuals who are representative of a large populace. A possible disadvantage is the risk of obtaining associations between infants and women of childbearing age that do not exist between pairs of infants and mothers when using a longitudinal design. We address the potential for such spurious associations in each step of our argument. First, we observed little difference between antibody levels among seroconverted women of childbearing age and the initial levels among newborns within each of the 2 defined groups. This suggests that the Rabbit polyclonal to ERCC5.Seven complementation groups (A-G) of xeroderma pigmentosum have been described. Thexeroderma pigmentosum group A protein, XPA, is a zinc metalloprotein which preferentially bindsto DNA damaged by ultraviolet (UV) radiation and chemical carcinogens. XPA is a DNA repairenzyme that has been shown to be required for the incision step of nucleotide excision repair. XPG(also designated ERCC5) is an endonuclease that makes the 3 incision in DNA nucleotide excisionrepair. Mammalian XPG is similar in sequence to yeast RAD2. Conserved residues in the catalyticcenter of XPG are important for nuclease activity and function in nucleotide excision repair level of antibodies is usually passed on from mother to child. This is in line with previous studies that showed that levels of GR 103691 maternal antibodies among children at birth were highly associated with the antibody levels of their mothers [11, 28]. Some previous studies reported an increase in antibody levels in infants at birth, compared with levels in their mothers; our study suggests this increase must be small, but this.
