Objective: The Relief System for Sufferers from Adverse Drug Reactions was created for the purpose of remedying issues such as medical expenses for people who experience an adverse drug reaction despite the proper use of a medicine.Methods: We used “decision data on adverse drug reaction payments” released by the Pharmaceuticals and Medical Devices Agency to investigate the payment of all medical supplies for adverse drug reactions associated with the HPV vaccine over the 7-year period between 2011 and 2017.Results: The HPV vaccine had a lower rate of supply than all other medical supplies. Medical costs and medical allowance accounted for the majority of supplies for the HPV vaccine. The most common response was “A causal linkage between adverse reactions and the HPV vaccine cannot be confirmed”, followed by “It is not recognized as medical care requiring hospitalization”.Conclusion: Many patients with an adverse drug reaction received no medical supplies, mainly for the reason of “undecidable”. With regard to these patients, it may be necessary to carry out a survey so that they can be judged rather than classifying them as ‘undecidable’.
