It's not clear whether Swanson is vaccinated against COVID-19. She has previously been critical of the shot on social media. In September, she suggested that vaccine mandates were instituted as a way to "make mo-money."
"Oh I see, so it behaves just like the flu," she wrote on Twitter alongside an article about COVID-19 immunity. "Every year a new flew strain arises & a new vaccine comes out for it, if you want to get one. That's exactly what this whole thing is, except this time they want to mandate vaccines so they can make mo-money."
On Monday, she responded to a headline referring to her as "anti-vax," denying the label.
"I have NEVER said I am anti-vax," she wrote.
It sounds to me like Swanson is not anti-vax, but is anti-mandate. It is a very common position.
