Facebook and Instagram will refer users who search for information about vaccinations via the social media to the World Health Organization (WHO) website, Facebook announces on its blog on Wednesday.

Disinformation about vaccinations and measles is regularly distributed on Facebook. For example, at the beginning of September a message is circulating in which an unreliable investigation about vaccinations is being shared, NUcheckt notes - that Facebook is checking for untruths - on Wednesday.

Facebook has been taking measures to combat disinformation about vaccinations for some time. For example, anti-vaccination groups and pages appear lower in the search results since March. Anti-vaccination advertisements are also prohibited.

In August, the social medium Pinterest already took measures to refer measles and vaccination searches to the WHO. Measles can be fatal, but the disease can be countered with two safe and effective vaccinations for children.
