Wearing her Formal Friday tiara, a black T-shirt that read "vax a nation" and "don't be a d***, get the prick" on the back, Barry wrote: "Super Saturday deserves a tiara. C'mon Aotearoa let's get vaccinated!"
She revealed she was heading off for her second jab today.
It's not the first time Barry has come under fire from anti-vaxxers for speaking out.
Last week she blasted back at poor-spelling anti-vaxxers who have now launched a petition calling for her to be fired.
The Seven Sharp host has had to endure a targeted online trolling campaign after encouraging Kiwis to do their bit during the pandemic and get vaccinated against Covid-19.
After calling them out for their attacks earlier this week, Barry has addressed a petition to "remove her from the airwaves", and even managing to misspell her first name in the process.
"The anti-vaxxers are the kings and queens of misinformation," she said.
