Sarah Jessica Blattner, a 14-year-old Israeli American girl with an underlying health condition, died in her sleep on October 12th reportedly from a heart attack after receiving one dose of the Pfizer vaccine five months earlier.

Her parents decided to finally speak out three months after her death and urged the public not to vaccinate their kids. In their case, it was a big "mistake."

Blattner was diagnosed with cancer when she was nine months old. She survived and has been living cancer-free for 11 years according to her Twitter post way back in 2020.
