It makes sense that they couldn't rule it out right away, but eventually did. It's really hard to tell what causes TM, so they can't look at an individual case and rule out the vaccine as the cause, but they can look at the overall results at the end of the study and if there's not a higher rate of TM in the experimental group than the control group, then they know it wasn't caused by the vaccine. Transverse myelitis also occurred during HPV trials but was ruled as unrelated to the vaccine.
