Sir,

Cervical cancer is the most common type worldwide. Human papillomavirus (HPV) is an important etiology of this cancer.[1] At present, the prevention of this cancer is possible since cervical cancer vaccine is available.[2] For vaccination, there is still an argument on the effective regimen. The topic that is widely discussed is the selection for two-dose or three-dose regimens for vaccinating the young women who should receive the cervical cancer vaccine.[2] Indeed, the two-dose and three-dose cervical cancer vaccination regimens are mentioned in several reports from different settings.[3],[4],[5],[6],[7],[8],[9] Many reports usually use the immunogenicity for judgment of proper regimen. For example, the study from India noted that the two-doe regimen could induce sufficient immunogenicity.[6] Sankaranarayanan et al. studied difference regimens and recommended the two-dose regimen for the Indian situation.[7],[8],[9] Similar observations are also reported in the study from UK and France.[4],[5] In another report from the Netherlands, the immunogenicity of vaccine in the two-dose and three-dose regimen is not different.[3] Nevertheless, the economical concern is also important in regimen selection.

In this short report, the author compares the two regimens. The cost–utility comparison based on the present epidemiology of HPV in Thailand is done. In analysis, the cost refers to the unit for each regimen reported by referencing tertiary hospitals in Thailand (Vibhavadi hospital, Bangkok) and presented in USD. The utility is referred to the expected adjusted immunogenicity determined in geometric mean titer at 36 months after vaccination as shown in previous validation study and presented in mMU/mL.[10] The path probability assignment is according to the recent data from epidemiological study on HPV in cervical smear samples in Thailand.[11] The primary data of utility quoted from the referenced study [10] and derived expected utility after assignment of path probability are shown in [Table 1]. Then, cost per utility values for two-dose and three-dose regimens are calculated. The final cost–utility analysis result is presented in [Table 2]. Based on this study, the three-dose regimen has less cost per utility than the two-dose regimen; hence, the three-dose regimen of cervical cancer vaccination should be used in the study setting. In conclusion, the three-dose regimen of cervical cancer vaccination is hereby recommended based on cost–utility analysis. The finding is an important topic and relevant to other settings [12],[13] including India. For each setting, the comparative cost–utility analysis is recommended.
