There is no vaccine to prevent hepatitis C infection. The best way to help prevent hepatitis C infections is to avoid sharing needles, razors, or personal hygiene products. If you get a piercing or a tatoo, make sure all the equipment has been sterilized properly.
The risk of transmission through sex is low, especially among monogamous couples. The risk increases if you have multiple partners, engage in rough sex, or have HIV or another sexually transmitted disease. To reduce the risk of spreading or getting hepatitis C through sex, limit the number of sexual partners you have. Use latex condoms each time you have sex, especially if you have multiple partners or there is a risk of contacting blood or open sores during sex.
Take other steps to avoid coming in contact with infected blood. Hepatitis C can live in dried blood. All people should use precautions when handling blood.
