The death of a child from measles in the UK has sparked a wave of misinformation on social media, especially from anti-vaccination influencers.

After the death of a child in Liverpool from measles, UK health authorities stepped up calls to vaccinate children, but were met with misinformation from the anti-vaccination movement. Influencers such as Ellie Grey spread false claims about the dangers of measles and the effectiveness of vaccines. Liverpool's director of public health highlighted the seriousness of the virus and the importance of vaccination, while the UKHSA stepped up communications to combat misinformation. The vaccination rate in Liverpool is around 74%, below the required 95% threshold for herd immunity. Misinformation continues to pose a threat to public health.
