Covid: chemicals found in everyday products could hinder vaccine

[LiberalArkie]

The successful uptake of any vaccine for Covid-19, a crucial step in returning a sense of normalcy after a year ravaged by the coronavirus pandemic, could be hindered by widespread contamination from a range of chemicals used in everyday products.

Small amounts of per- and polyfluoroalkyl (or PFAS) chemicals are commonly found in the bodies of people in the US, as well as several other countries. These man-made chemicals, used in everything from non-stick pans to waterproof clothes to pizza boxes, have been linked to an elevated risk of liver damage, decreased fertility and even cancer.

But scientists warn some of these chemicals can also cause another little-known but potentially significant defect by reducing the effectiveness of certain administered vaccines. This impediment could cast a shadow over efforts to roll out a Covid-19 vaccine to enough people that restrictions on day-to-day life are eased.

“At this stage we don’t know if it will impact a corona vaccination, but it’s a risk,” said Philippe Grandjean, an adjunct professor of environmental health at the Harvard School of Public Health. “We would have to cross our fingers and hope for the best.”

Seems like that would have been reflected in the testing Pfizer and Moderna have been doing...? If it reduced the efficacy by half you wouldn't be seeing numbers at 90% effective and higher.

2. I think the article was indicating maybe that they do not know, Maybe most of the test subjects

were out of the U.S.
