Your friend has taken the complete course of hepatitis B vaccine, let me share with you that hepatitis B vaccination is very effective in providing protection against hepatitis B infection. 3 doses are sufficient .The chances of acquiring hepatitis B infection are very low and only possible if one has not acquired adequate protection and antibodies after the vaccination. It is important to protect oneself from infected blood and other body fluids like blood of an infected person, semen and vaginal secretions. It is possible that the procedure might have given him hepatitis B infection but the cause cannot be confirmed without thorough evaluation .Antiviral therapy is only indicated in people who are chronically infected and have persistently elevated SGPT which is a marker of liver damage, and HBV DNA levels. Routine follow ups are very essential along with regular blood monitoring to see if the virus is still active in your body and liver function tests to know how well your liver is working. Consult a hepatologist and get your doubts clarified. Keep me posted.
Best luck and regards!
