I don't know how are they even alive

Mockery of false anti-vaccine conspiracy theories

This is a 4-panel reaction meme using clips from the animated series Futurama. The first panel labels the character Leela as 'an illiterate Karen', who states the widely disproven conspiracy theory that vaccines cause autism in young children, so she has chosen not to vaccinate her children at all, while Bender looks at her. The second panel shows Bender laughing loudly, with the text 'Ha ha ha ha ha ha ha'. The third panel has Bender saying 'Oh wait, you're serious. Let me laugh even harder!'. The fourth panel shows Bender laughing even more intensely while Leela looks annoyed and crosses her arms. The meme mocks people who spread dangerous, false anti-vaccine misinformation, highlighting how absurd and irresponsible their beliefs are, as unvaccinated children are at high risk of contracting preventable, potentially life-threatening illnesses.

This meme originates from Reddit meme communities, as specified in the provided additional information. It uses a popular, long-running 4-panel meme template taken directly from a scene in the animated sitcom Futurama, where Bender reacts to an absurd, obviously wrong statement by laughing hysterically, then laughing harder when he realizes the speaker is being serious. This iteration of the template targets anti-vaccine activists and the 'Karen' stereotype of entitled, misinformed people who spread harmful public health misinformation.
