g. wound healing) and to manipulate maternal physiology to enhance resource transmission to offspring (e. Fathers were less susceptible than other household members (estimated relative susceptibility of fathers = 0.

To evaluate pregnancy outcomes of women who received tetanus, diphtheria, and acellular pertussis (Tdap) vaccination at or after 32 weeks of gestation.Additionally, the association of fetal cells with breast cancer may be subtype‐specific, as higher levels of fetal cells were reported in the tissue of women diagnosed with HER‐2 subtype of breast cancer, while lower levels of fetal cells were associated with estrogen receptor/progesterone receptor positive tissue 53. Testing multiple loci will likely also improve the ability to detect extremely low levels of fetal cell microchimerism. Below we expand upon our predictions and then review the current literature regarding the presence of fetal cells in tissues involved in resource allocation and the association of these cells with maternal health or disease. Recently, the Dutch Health Council advised that all pregnant women in the Netherlands be vaccinated against pertussis in a vaccination programme.

In this review, we use an evolutionary framework to make testable predictions about the role of fetal microchimerism in lactation, thyroid function, autoimmune disease, cancer and maternal emotional, and psychological health.In the fetal circulation a continuous rise in the level of both IgG and IgA was observed between 17 and 41 WG. However, a murine model of breast cancer found that high‐grade tumors harbored significantly more fetal cells than low‐grade tumors 58 and fetal cells have also been found in the tumor stroma of human females 59. Fetal cells increase in frequency in the maternal body with increasing gestational age 7, 8 and have been identified in maternal blood and tissues for decades following birth 9, 10. Fetal level of IgG at 17-22 WG was only 5-10% of the maternal level and at term exceeded the maternal level reaching a value of 11. A review of the published data on duration of immunity reveals estimates that infection-acquired immunity against pertussis disease wanes after 4-20 years and protective immunity after vaccination wanes after 4-12 years.

Maternal‐fetal conflict not only predicts the evolution of fetal adaptations to enhance resource flow to offspring, but also maternal countermeasures to limit that flow 3. Further, fetal cells have been detected at sites of inflammation in the maternal body, including skin lesions of women with polymorphic eruptions of pregnancy (PEP) 85, rheumatoid nodules of patients with RA 86, and in the goiter of a patient with thyroid disease 68. If fetal cells are able to migrate to the breast and up‐regulate milk production either through producing factors that manipulate maternal mammary glands or by differentiating into mammary gland themselves, this could benefit offspring fitness. One likely candidate mechanism for maternal countermeasures is the targeting and elimination of fetal cells by maternal immune cells. In countries with no pertussis booster until school age, continued monitoring of protection against pertussis is essential.

Infants younger than 3 months were also the only age group in which there were fewer cases in 2013 than in 2011 (118 cases in 2011 vs 72 cases in 2013), before the resurgence. Recommending immunization from the second trimester onwards would widen the immunization opportunity window and could improve seroprotection. A casual role of fetal cells (and maternal immune response to fetal cells) in maternal health or disease has not yet been definitely shown. We included six efficacy trials with a total of 46,283 participants and 52 safety trials with a total of 136,541 participants.
