Mark Zuckerberg's Facebook page is quickly becoming a collection of feel-good family moments - peppered with Oculus Rift promotions.

The Facebook chief executive has become a stay-at-home dad to daughter Max, his profile page reflecting his new-found joy in fatherhood as he shares his baby's milestones.

The latest of these was a trip to the doctor last week for wee Max, dressed in a colourful hooded onesie, to get vaccination shots.

But this latest post incurred much more than a string of "aww"s from Zuckerberg followers.


Collecting over 74,000 comments, it was quickly flagged as an expression of support for vaccinating by the social media billionaire.

Anti-vaccination crusaders shared enraged comments such as: "Vaccine is poison for human kind. It kills more people than it helps. I wish people don't take it as an example here."

Another wrote: "I am sorry to see you unnecessarily putting your kid at risk by responding to faux science and propaganda."

Zuckerberg has, and I'd bet the farm, that he has no intention of vaccinating and dumbing down his child. However, what he, Bill Gates, and other elites, wants [sic] for your children, and a whole generation, is much, much different than what they want [for] their own kids. It saddens me you people can't see how blatant this post is."

In February last year, Zuckerberg indeed posted about a book he was reading on the topic.

Almost a year later, he's signed up to go ahead with vaccinating his daughter, a move many of his followers applauded.

""Thanks for protecting your child, and other children who can't be vaccinated, and for supporting science!", wrote one user.

"What a little cutie!! Thanks for taking care of your baby (and other peoples' babies!)", echoed another.
