HPV vaccine probably did not cause sudden death in this young girl

A young girl receives an HPV vaccine at school and then suddenly dies. Was the vaccine the cause of sudden death? In this case, it appears that Natalie Morton (age 14) had a serious medical condition and even a large tumor in her chest. According to a news story on Medscape:

preliminary postmortem revealed that she had "a serious underlying medical condition which was likely to have caused death," according to Caron Grainger, MD, joint director of public health in Coventry.

Regardless, several health authorities in the United Kingdom announced that they were temporarily suspending their HPV vaccination programs.

This story on the BBC reveals that this girl had a large infiltrating tumor in her chest and this tumor was affecting her heart and her lungs. Since both are vital organs, it's possible that the timing of the vaccine simply had nothing to do with her death. In any case, this is a sad story and my heart goes out to her family and loved ones.
