Actor in anti-vaccine protest on Twitter comes under fire after attaching picture, but apologises after contact from boy's family

Jim Carrey has been forced to apologise after tweeting a picture of a child suffering from autism and tuberous sclerosis without his family's permission.

Carrey tweeted the picture of Karen Echols' son Alex as part of a protest against recent legislation in California that removed the personal-belief exemption from public health vaccination programmes.
