Brief summary: This study is a cross-sectional study. The study aims to determine the levels of immunity against hepatitis B virus and varicella-zoster virus in medical students.

Detailed description: This study is a cross-sectional study aimed at determining the levels of immunity against the hepatitis B virus and varicella virus in medical students. Additionally, it aims to compare the rate of increase in immunity levels before and after receiving the hepatitis B and varicella-zoster vaccines in medical students. Medical students aged 18 years or older are included in the study.
