When Katy Fyksen got a heavy period a few days after she received her second dose of the Moderna COVID-19 vaccine, she didn’t consider there might be a link.
The 43-year-old Plainfield woman hadn’t had a period in over a year and a half because of her Mirena IUD, so the sudden red flow was a surprise. But she didn’t think about the timing in relation to when she received her vaccine until she saw a Twitter thread.
“I didn’t really think that it was anything until I saw that someone had said that, that it might’ve been a symptom or a side effect of the vaccine. It was like, ‘Oh, that’s interesting,’” she said.
