Revealing that because of her vaccination status and recent recovery, it was safe to assume she had super-immunity, she talked about how it wouldn't change the way she would continue to take precautions.
"Psychologically, emotionally, I feel better with that knowledge," she said. "But remember, it's not a one-size fits all," as she discussed people with compromised immune systems and other ailments.
The news of Jennifer's unfortunate diagnosis was revealed live by her co-stars Amy Robach and TJ Holmes on her behalf.

TJ clarified, however, that she was doing fine, adding: "She did get some mild symptoms, but she's just resting and she is fine, we just wanted to share that."
Along with the snippet, Jennifer wrote: "Thank you @abcgma3 @ajrobach @officialtjholmes for the get well wishes… I have Covid19: feeling MUCH better today, after 1-2 days of feeling like I had a really bad cold.
