Litigation concerning hepatitis B vaccination provides a good illustration of the difficulties courts encounter when deciding on compensation claims in which scientific uncertainty, whether real or perceived, is present. Despite the difference in approach to vaccination - an obligation in France and a recommendation in Germany -, their vaccine coverage is comparable, as are their regimes of compensation for damage attributed to vaccination, whether on the basis of producer liability or national solidarity. Confronted with scientific uncertainty, German and French courts choose to make use of presumptions to establish legal causality that is not contingent on scientific causality. German and French case law diverge however, with regard to their relationship to scientific criteria of causality, the volume of court cases, and consideration of claims, highlighting what seems to be a distinctive situation in France.

法院的科学不确定性。法德比较乙肝疫苗接种诉讼的比较观点

有关乙肝疫苗接种的诉讼很好地说明了法院在确定存在科学或不确定性的赔偿要求时法院遇到的困难。尽管疫苗接种方法有所不同（法国的一项义务和德国的一项建议），但无论是基于生产者的责任还是出于民族团结，它们的疫苗覆盖率以及因疫苗接种而造成的损害赔偿制度都具有可比性。面对科学不确定性，德国和法国法院选择使用推定来确立法律因果关系，而这种因果关系并不取决于科学因果关系。但是，德国和法国的判例法在因果关系的科学标准，法院案件的数量以及对索赔的考虑方面存在分歧，
