“…The French Court of Cassation has eased the burden of proving causation through five decisions issued on May 22, 2008, even in the case of conclusive scientific uncertainty on the realization of the causal relationship between the defect and the damage, 4 it went in one of its decisions (if the work for liability for the defective product requires proof of damage, and the defect is the existence of a causal relationship between the defect and the damage, such evidence may be proven by marriage provided that it is serious, accurate, consistent and consistent with reality) 5 The researcher believes that the direction of the French Court of Cassation falls within the broad concept of the text of Article 1382 of the French Civil Code, which granted the judiciary wide discretion in estimating the Qur'an that was not stipulated by law, such as the temporal convergence between the vaccine and the onset of the disease or the absence of a personal or family history of the disease, and the most important thing is the number of those affected by the vaccine after vaccination.

It follows from the preceding that the discretionary power granted to the courts under the text of Article 1338 of the Civil Code oven, Whether related to the defective nature of the vaccine or the causal relationship between defect and damage, has 4 Civil.…”
