'Sister Wives' star Gwendlyn says it's 'ironic' that Kody and Robyn 'don't believe in vaccines' despite their strict COVID rules

• Gwendlyn Brown said that her dad Kody and his wife Robyn are unvaccinated. 
• She called their choice "ironic" considering the strict COVID-19 rules they followed. 
• Kody did not immediately respond to Insider's request for comment. 

TLC's "Sister Wives" star Gwendlyn Brown said in a YouTube video on Thursday that her father Kody Brown's strict COVID safety rules were "ironic" considering he and his wife Robyn remain unvaccinated.

Gwendlyn, 21, posts weekly videos reacting to recent episodes of her family's reality show since public interest in their lives has increased now that Kody is only romantically involved with his fourth wife,, Robyn Brown.

"So, of my parents, I'm pretty sure all of them except for Robyn and my dad are vaccinated," Gwen said at the end of the video during a segment answering fan questions. "Those two don't believe in vaccines, which is really ironic considering everything that's been going on on the show." 

During the pandemic, Kody's strict COVID rules included requiring everyone to change clothes immediately upon arriving home if they went out in public and disinfecting their mail, among other things.

Kody's second wife Janelle Brown, and his ex Christine Brown, who was married to him at the time, refused to follow his guidelines and visited their adult children who lived outside of Flagstaff, Arizona, during the pandemic. Viewers saw this cause tension between Kody and both women starting in season 15 of "Sister Wives."

Kody is currently "divorced" from Christine and "separated" from Janelle — he was spiritually but not legally married to both. His first wife, Meri Brown, complied with his COVID rules, but the former couple announced the end of their "spiritual marriage" in January 2023. 

Differing views about COVID-19 also caused tension between Kody and some of his children with Janelle and Christine, including Gwendlyn, Christine's biological daughter. 

In her recent video, Gwendlyn also responded to a fan who wondered why Kody spent so much time with Robyn and failed to reach out to his other wives and children as much.

"I have no idea, genuinely," she replied. "I think that it would've been so simple to do that. We did do that a few times and it was super easy and very uncomplicated. I think that it's just because he prefers to spend time with Robyn's side of the family." 

In a previous "Sister Wives" rewatch video posted to YouTube, Gwendlyn admitted that she doesn't like Robyn "as a person." She added that watching her interviews and behavior on "Sister Wives" episodes "makes me like her less for sure."

All episodes of "Sister Wives" are available to stream now on Paramount+.
