Endocrine disruptors, such as those of the perfluorinated family (PFAS), reduce the levels of certain antibodies present in our body. The big unknown for researchers right now is whether PFAS could wipe out Covid-19 antibodies.

- Future vaccines against Covid-19 could be less effective because of endocrine disruptors.
- Certain families of endocrine disruptors reduce the number of antibodies present in the body.
- For the moment, it is still too early to know if the antibodies that we will develop with the vaccine against Covid-19 will be viable in sufficient numbers not to be weakened by endocrine disruptors.
The solution against Covid-19 could be less effective than expected because of the pollutants around us. Endocrine disruptors, which are present in most of the objects that make up our daily lives, can disrupt the proper reception of the treatment by our body.
As described The Guardian in one article, per- and polyfluoroalkyl substances (PFAS) are everywhere: in pizza boxes, in the waterproofing of a jacket, in certain fire-fighting foams or on the non-stick coatings of stoves. These endocrine disruptors can increase cancer risk, reduce fertility and cause liver damage.
Reduces diphtheria and tetanus antibodies
The British daily followed a study conducted by Philippe Grandjean, assistant professor of environmental health at Havard, in order to know the harmfulness of PFAS on our daily lives. In their conclusion, the researcher points out that children who are exposed to PFAS have a markedly reduced concentration of antibodies against diphtheria and tetanus. Other tests have been conducted on adults with similar results. Philippe Grandjean conducted an experiment on another type of other endocrine disruptors, PFBAs, which could accumulate in the lungs and increase the severity of Covid-19 infections.
If the vaccines made by the couple Pfizer / BioNTech and Moderna have nothing to fear because they use messenger RNA, other vaccine compositions will be more problematic, especially for those who rely on peaks of proteins to help the body. “People with high PFAS exposure have non-protective and very low antibody levels after four vaccinations against diphtheria and tetanusemphasizes Philippe Grandjean. So if a vaccine for Covid is similar, PFAS will likely inhibit a vaccine response. But that’s an unknown at this point..”
At least 200 million people affected in the United States alone
Endocrine disruptors have an extremely long lifespan in the body, especially if they make up objects that we use every day. In the United States alone, an estimated 200 million people eat and drink food that has come into contact with PFAS.
In his program, President-elect Joe Biden promised to crack down on these endocrine disruptors, in particular so that they no longer end up in the water.
