The chemical, perfluorooctanoic acid, or PFOA, has been linked to kidney cancer, birth defects, immune system disorders and other serious health problems.
Their initial gut communities more closely resemble that of their mother's (and father's) skin, which is less than ideal and may account for higher rates of allergy, asthma and autoimmune problems in C-section babies: not having been seeded with the optimal assortment of microbes at birth, their immune systems may fail to develop properly.
In the weeks after birth, babies' immune systems aren't fully functional and they're very vulnerable to infection.
At birth the immune system has genetically inherited mechanisms, but it lacks data.
41 In fact, the subsequent addition of bacteria to germ-free animals after birth influences immune development, improves sociability, and reduces anxiety, 43– 45 emphasizing the importance of the microbes.
NCER programs also support prevention and/or treatment of childhood asthma, preterm births, leukemia, immune system disorders, neurodevelopment problems, autism spectrum disorder and obesity.
This intriguing finding confirms that immunization at birth primes the immune system.
After Kasper's researchers injected pregnant mice with antibodies from immunized women, the mice gave birth to pups immune to GBS. "The characteristics of the antibody were what we had hoped for," says Kasper, who with Carol Baker of Baylor College of Medicine in Houston detail the clinical trial in the latest issue of the Journal of Clinical Investigation.
However, population ageing and consequent replacement of immune birth cohorts by cohorts with low natural immunity, and the relative increase of the size of the elderly population (for whom the risk of developing symptomatic infection and associated morbidity and mortality is greatest), had a compensatory effect with respect to the estimated future burden.
His legacy lies in medicinal chemical discoveries we continue to count on for medicating glaucoma, rheumatoid arthritis, chemical birth control, and immune suppressing medicines for organ transplants.
