The cafe said this morning that the original comment and the replies did not come from the cafe themselves.
"It's not from us, it's from somebody else," the cafe's manager told the Herald this morning.
"A page was hacked by an anti-vaxxer, unfortunately. To make us look bad, that's what they do."
In a statement posted to Facebook this morning, the cafe's owner clarified their position, suggesting that the post was made by someone who had access to the Facebook page and confirming that they did not approve the message.
"In light of the recent activity on our Facebook page I want to let you know I do not hold the admin rights for my Facebook page, the recent posts made were not approved by me and are not views held by me or any members of my current team," he wrote.
"I am working with Facebook to get this rectified. I would like to thank the wonderful community of Green Bay for their ongoing support during this time."
