FRIDAY, Aug. 21, 2015 (HealthDay News) -- New mothers may inadvertently pass industrial chemicals along to their babies through breast-feeding, which might lower the effectiveness of some childhood vaccinations, researchers report.

The class of chemicals, called perfluorinated alkylate substances (PFASs), are widely used in consumer products to make them resistant to water, grease and stains.

A Harvard-led research team found that a baby's blood concentration of PFASs will increase by 20 percent to 30 percent every month they're breast-fed.

This phenomenon worries study co-author Dr. Philippe Grandjean, because earlier research has shown that PFASs can cause vaccinations to either fail or to be much less potent.

"This is absurd. We're trying to prevent diseases by vaccinations, and we also are encouraging mothers to breast-feed because human milk is the ideal nutrition for the child, and the child's immune system is also stimulated by components of human milk," said Grandjean, an adjunct professor of environmental health at the Harvard T.H. Chan School of Public Health in Boston. "And now we're finding that there are contaminants in the milk that have the opposite effect of breast milk that are decreasing the impact of childhood immunizations."

PFASs can be found on waterproof or water-resistant clothing, and on furniture or carpeting treated for stain resistance, Grandjean said. The chemicals are also used in food packaging such as microwave popcorn bags and takeout pizza boxes.

"There's no way that young women can actively prevent their own exposures to these substances," he said.

An earlier study published by Grandjean showed that 7-year-olds with twice the blood concentration of PFASs had about half of the levels of tetanus and diphtheria antibodies as children with average PFAS levels.

"We found that for each doubling in exposure to PFAS, the child has an increased risk that the vaccination will not take," he said. "The risk increases between two- and fourfold for each doubling of the child's exposure."

As a next step in their research, Grandjean and his colleagues decided to look at whether breast-feeding might be a source of PFAS exposure for babies.
