"Tobias Ulbrich, a lawyer at Rogert & Ulbrich, told Reuters he aimed to challenge in court the assessment made by European Union regulators and German vaccine assessment bodies that the BioNTech shot has a positive risk-benefit profile.

German pharmaceutical law states that makers of drugs or vaccines are only liable to pay damages for side-effects if "medical science" shows that their products cause disproportionate harm relative to their benefits or if the label information is wrong."

Hmm so if it does more harm than good, the case is won. It'll be fascinating to see what they choose to present.
