"That's how strongly I'm taking what you're saying."
In the U.S., 48% of the population, or 159.5 million people, are fully vaccinated, according to the Centers for Disease Control and Prevention (CDC).
This isn't the first time Gayle has spoken out about the importance of getting vaccinated, as she told Stephen Colbert it was her "superpower."
"I was so afraid to leave the house," she said of her time in quarantine. "We were broadcasting from here, so I'd literally go from my bedroom to the TV room to the kitchen to the bedroom to the TV room. For excitement I'd go stand in the living room and wave at the birds! 'Hi, birds! Hi!' I was so afraid."
"But now, Stephen, I am vaccinated," she continued. "It is my superpower. I am vaccinated."
