"I want it to be clear that it is because of the vaccine I’m fine. I think if I weren’t vaccinated, I would have, like, died, because it was bad," she said to the radio host Howard Stern. 

Eilish went on to say that her brother, Finneas, who also was on the radio show, didn't contract the disease despite being in tight-knit quarters with his little sister.

"It also saved Finneas from getting it, it saved my parents from getting it, saved my friends from getting it," she said.

However, the singer revealed that for her, getting COVID was no joke. To this day, she said she still suffers from some side effects, and that it lasted a really long time.

"I mean, I didn’t die," she joked. "And I wasn’t gonna die, but that does not take away from how miserable it was. I mean, it was terrible."

"I still have side effects," she added. "I was sick for, like, two months almost. This was in August, a couple of months ago."

Eilish appeared on Saturday Night Live over the weekend.
