Some people carry the virus and are infectious to others all their lives, though they themselves may have no symptoms of the disease. The Hepatitis B virus is transmitted through blood, semen, vaginal secretions and other body fluids. The virus can live outside the human body for extended periods, thereby increasing the risk of infection for those who use contaminated articles such as razor blades, needles or toothbrushes. Some of today's university students were vaccinated by their pediatric caregivers. Those who find they have not had the series of three immunizations can be vaccinated at home or at Gannett, Cornell University Health Services.
Some health plans pay for the immunizations which usually create lifetime immunity to infection.
Booster shots can be given if indicated. If you prefer, go to your home health-care provider. Talk with your partner about past risks and the timing of subsequent STD tests. Be sure sexual partners have been vaccinated and are immune. Practice safer sex.
