If you read the paper it discusses causal mechanisms extensively. Reality is you can't get a paper about vaccine side effects out, or keep it out, unless you grovel in the intro and state that vaccines are wonderful, safe and everyone should take them. Skip the obligatory morality disclaimer at the start and you'll see lots of case studies where causality is obvious, along with discussions of how it works, e.g. "A 67-year-old patient from Hispanic had petechial rashes on her legs and chest 2 weeks after receiving the first dose of COVID-19 vaccine (Pfizer-BioNTech). Then, she received the second dose of the vaccine two days prior to developed bleeding in her gums, a rapid rash covering her body and a subconjunctival haemorrhage in the right eye" ... "There are several putative mechanisms by which COVID-19 vaccine triggers immune thrombotic thrombocytopenia (ITT). First, Greinacher and colleagues considered that COVID-19 vaccination causes a rare ITT mediated by activation of antibodies against PF4 that stimulate platelets through their Fcγ receptors" ... "First, an interval of 1–3 weeks between vaccination and the onset of symptoms supports a temporary causal relationship" ... "For instance, a 30-year-old man, without family history of kidney disease, developed fevers, headache and brown-coloured urine, coupled with new-onset haematuria and proteinuria 1 day after vaccination, eventually diagnosed with IgA nephropathy"
