5. Study Description
Brief Summary
The purpose of this study is to determine whether short-term Atorvastatin can increase the immunity response to hepatitis B vaccination in vaccine Nonresponders.
Detailed Description
20 person of vaccinated individuals who have HBsAb<10 after 3 dose hepatitis B vaccination who called Nonresponders will be randomly allocated in 2 groups. one group receive short-term Atorvastatin and other group receive placebo.both group will be vaccinated with hepatitis B vaccine and then immunity response will be measured.
