This isn’t a paper, it’s an editorial, and it’s utter trash, printed in a bad “journal” (New Scientist is essentially a mass-market magazine, on par with Discover). The only evidence advanced for the claim is this:

This is a survey of parent-reported symptoms in 129 children, and of the “long-term” symptoms, all are vague, (e.g. headache, fatigue, muscle pain) overlapping substantially with the aches and pains of daily life.

They don’t even bother to link to it directly in the editorial; they simply mention the doi in the text. This wasn’t even proofread by an editor.
