Post-vaccination immunity against diphtheria, measles, tetanus and pertussis in children exposed to environmental chemical factors

An assessment of post-vaccination immunity against diphtheria, measles, tetanus and pertussis in children with increased levels of chemical toxicants, caused by environmental exposure was conducted. It was determined that the levels of post-vaccination 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. A true relationship between a decrease in the levels of specific post-vaccination antibodies and an increase in the levels of lead, chromium, manganese and o-cresol in the blood was identified.
