Instagram is blocking hashtags linked to verifiably false information about vaccines in an attempt to prevent a public health disaster. It's responding to public pressure for social media platforms to take greater responsibility for the misinformation they host and help spread.

A growing awareness of fake news and the proliferation of sponsored posts on social media has seen the trustworthiness and authenticity of online influencers come into question. How are established experts, nano-influencers, and CGI characters rebuilding confidence and digital relevance?

As the anti-vax movement grows in the US, Gen Zers are turning to community-based networks such as Reddit to get accurate information on vaccinations. Though they may host plenty of 'fake news', social platforms can also provide a welcome source of support.
