It’s just one, thankfully rare incident. But it’s a symptom of the creeping misinformation hitting some of Brazil’s most remote communities.

But rather than being a vestige of traditional ideas or village life, rumours about health and vaccines are being spread in a very modern way.

Mobile phone operators in Brazil often include free data in their user plans, but the package is limited only to select social media platforms. These plans, popular in poorer, rural and indigenous communities, allow Brazilians to spend hours online for free – but limit access to other apps and alternative sources of online information.

It means Brazil’s poorest can find themselves unable to check what they’re reading on chat apps – and stuck in a misinformation bubble.

And the fact that some religious and political leaders – including President Jair Bolsonaro – have been spreading falsehoods and anti-vax messages doesn’t help either.

In Brazil, the uptake of vaccines in indigenous communities is now significantly lower than expected – but the news isn’t all bad. We meet indigenous people trying to convince their families to take the jab.
