Teen Mom Mackenzie McKee slammed for claiming her body is ‘messed up’ by being close to vaccinated MTV crew members

One person wrote: "Imagine not understanding birth control and trying to tell people about 'science'. She is dumb as a box of rocks."

Another said: "Omg. Antivaxers are so stupid."

Many people defended the science behind the vaccines, as one person said: "I fully support people who choose not to get the vaccine - it is their choice, just as it was my choice to decide to get the vaccine.

"However, I cannot support these IDIOTS who support and spread these ridiculous theories and rumors about the vaccine. It is so reckless of her to put this uneducated opinion out there when she has so many followers, some of whom are, unfortunately, easily swayed.

"What a slap in the face to our education system and SCIENCE."

Others wondered if Mackenzie's body is "messed up" because she's pregnant, as one person commented: "I’ll wait for the pregnancy announcement."

Mackenzie is no stranger to backlash and is regularly criticized by MTV fans.

She married husband Josh in 2013, while the couple share kids Gannon, nince, Jaxie, seven, and Broncs, four.

Mackenzie has been open about her troubled relationship with Josh and recently adding: “Baby, I know my self-worth.”
