Plasma cells in the blood (memory B cells) as well as serum antibody (IgG) recognize viral protiens both on viral particles and infected cells. These plasma cells then travel to the germinal center of lymph nodes and start to divide producing effector B cells. These effector cells serve two purposes, the first is to produce high levels of neutralizing antibody, the second is to prime killer T cells. The antibodies bind to viral particles in the peripheral blood and promote their phagocytosis and degridation in the lysosomes of effector cells. The killer T cells recognize viral protiens displayed on the major histocompatibility class I (MHC I) receptors on infected cells and initiates cell lysis to kill the infected cell. Of course this is very simplified and there are other immune cell functions not to mention many cytokine responses that are involved in the process.
To simplify: if you responded well to the vaccine (which most people do) your immune system is primed to fight hep B virus and will kill any virus that enters your body and any of your cells that it happens to infect (within reason.) If you want to make sure that you still have immunity to hep B, you can have your doctor order a serum antibody titer assay also known as post vaccine testing.
If you are exposed to hep b but have not had the vaccine, hepatitis B immunoglobulin (HBIg) can be administered to prevent infection. It is usually administered with the hep B vaccine.

Nothing should happen since your had the vaccine. I had a friend who I took in to a doctor for hepatitis and the doctor and I both had to take the vaccine. My friend was admitted to a hospital. But since I had come in contact with it, I still have B in my blood and can't give blood etc. But it never affected me after all these many years.

The purpose of a vaccine, is to prevent being infected with the disease. If you have had the Hep B vaccine, and came in contact with someone with the disease, you have less than a 1% chance of contracting the illness. If you are extremely worried, go to your doctor and get tested, but you shouldn't be worried.

Nothing, that's what the vaccine is for. By the way, after getting the series of shots for the vaccine you are supposed to get your blood titred to see if the vaccine took hold. Many people dont do that.

Just hope you weren't exposed to this person's body fluids as you will surely be put at risk...

you should be fine. but call the doctor and make sure.

You are probably immuned.
