According to researchers, everyday objects could interfere with the effectiveness of the vaccine against the Coronavirus. We explain why.
To date, many countries are struggling to find the ideal formula for a 100% effective vaccine. Yes, since early 2020, the Covid-19 strikes full force and continues to create second waves since the first containment last spring.
In recent days, several laboratories have announced an efficiency of more than 90% on their vaccine trials. Pfizer-BioNTech, AstraZeneca, or even Moderna, nearly 95% effective according to the latest information. Many are currently in phase III and ready to be put on the market by the end of 2020 or early 2021. A ray of hope for the world, which has no less than 55 million cases since the start of the pandemic.
No to chemicals
Unfortunately, according to information from our colleagues from The Guardian, researchers would be quite pessimistic about the effectiveness of a vaccine. The reason ? The presence of chemicals in many everyday objects. Which will you tell us? These are theperfluorés et polyfluorés (PFAS).
Reported by the French authorities, they remain very dangerous for health, according to information relayed by Yahoo Newss. But initially, these substances are found in many products that we use every day.
A less effective vaccine?
According to The Guardian, if the possible effects of these products have been identified for years now, others, more recent, have just been unveiled. They could “cause another little-known but potentially important fault by reducing the effectiveness of certain vaccines given“,
“At this point, we don’t know if this will have an impact on a Covid-19 vaccination, but it is a risk. Fingers crossed, ”said Philippe Grandjean, professor of environmental medicine at the University of Southern Denmark and the Harvard School of Public Health.
In 2018, the same professor made it clear through new research that the antibodies exposed to PFAS had been reduced, after being vaccinated against tetanus and diphtheria.
“People at high exposure to PFAS have unprotective and very low levels of antibodies after four vaccinations against diphtheria and tetanus. So if a vaccine for Covid-19 is similar, PFAS will likely inhibit a response from one. vaccine. But that’s an unknown at this point “.
