Post-vaccinal Immunity to Diphtheria, Measles, Tetanus and Pertussis in Children Exposed to Environmental Chemical Factors1

چکیده
An assessment of post-vaccination immunity against diphtheria, measles, tetanus and pertussis in children with increased levels of chemical toxicants, caused by environmental exposure, determined that the levels of postvaccination antibodies in this group of children were significantly lower than those in children living in environmentally favorable areas and that disorders in the development of post-vaccination immunity were observed 1.5 to 2.4 times more often. We identified a true relationship between a decrease in the levels of specific postvaccination antibodies and an increase in the levels of lead, chromium, manganese and o-cresol in the blood.

BACKGROUND Pertussis occurs in older children, adolescents and adults due to waning immunity after primary vaccination. Booster vaccination for pre-school children has been recommended in Italy since 1999. In this study (NCT00871000), the immunogenicity, safety and reactogenicity of a booster dose of reduced-antigen content diphtheria-tetanus-acellular pertussis-inactivated poliovirus vaccine (...

The Centers for Disease Control (CDC) defines vaccination as the injection of weak disease-causing agents that help the body develop immunity against specific infectious diseases (CDC, How Vaccines Prevent Disease 2009). Scientists hope that "through vaccination, children develop immunity without suffering from the actual diseases that vaccines prevent" (CDC, How Vaccines Prevent Diseases 2009)...

BACKGROUND Measles vaccines (MV) have sex-differential effects on mortality not explained by protection against measles infection. OBJECTIVE The authors examined whether whole-cell diphtheria-tetanus-pertussis (DTP) vaccine has sex-differential and non-specific effects. DATA SOURCES AND ELIGIBILITY Following previous reviews and a new search, the effect of DTP on mortality up to the next va...
