An Australian anti-vaxxer mom is in quite a spot after giving trick-or-treaters lollipops infected with chicken pox for Halloween.

Posting in a private Facebook group “Stop Mandatory Vaccination,” Sarah Walker claimed that her son had recently come down with the pox. She said, tainting Halloween candy would help give the kids chicken pox, making them immune for life, according to a Australia’s popular news site news.com.au.

“So my beautiful son [redacted] has the chickenpox at the moment and we’ve both decided to help others with natural immunity this Halloween!” Walker reportedly wrote in the group. She was also willing to sell the infected lollies. “If anyone else would like some for their children happy to send via post for $1 plus postage to your location.”

Police are reportedly investigating Walker’s claim, according to report by The Hill.

Walker’s story mimics the idea of “pox parties.” The parties saw parents put their healthy children in the same room as kids that were sick with chicken pox, in the hope that their kids would contract the disease and “be immune for life.” Although this trend was popular before 1995 when a vaccine for chicken pox did not yet exist, it has now seen a bizarre comeback, with the The World Health Organization recognizing “vaccine hesitancy” as one of the top threats to global health in 2019.
