Polio vaccine in the crossfire of misinformation

LIBREVILLE: As scientists around the world rush to find a vaccine to stem the spread of Covid-19, another deadly disease, polio, has become the latest target of misinformation campaigns online, reports AFP.

The World Health Organization (WHO) celebrated the announcement on August 25 that Africa had eradicated the wild poliovirus—a landmark in a decades-long fight against the crippling disease.

However, there still exists a version of the illness known as vaccine-derived polio, which occurs in rare incidents when the weakened virus in the vaccine mutates. It particularly affects countries with low immunisation rates and poor sanitation, health experts say.

Two days after the WHO’s announcement, the UN confirmed that more than a dozen cases of vaccine-derived polio had sprung up in nine states across Sudan.

The outbreak added further fuel to the already prolific spread of conspiracy theories pushing false claims about vaccination on social media.

Conspiracy theory groups promptly reported the outbreak in articles decrying “one of the biggest public health scandals of the decade”, singling out the WHO and billionaire Microsoft founder Bill Gates in their attacks.

A misleading article blaming a “Gates-funded vaccine” for “causing” the outbreak has been shared more than 8,000 times in Facebook groups from the US and Canada to Colombia.

The claims have also been circulating in Europe, with a French version of the article shared in various groups in France and Belgium.

But the article fails to mention that the cases involved people who had not been immunised themselves.

Gates, whose eponymous foundation has ploughed billions of dollars into making vaccines against diseases like polio, malaria and HIV, is a regular target for fringe groups accusing him of benefiting from vaccination or even using them for harm.

In spring, Facebook posts shared tens of thousands of times falsely claimed that a polio vaccine tested by the Bill and Melinda Gates Foundation paralysed 490,000 children in India.
