Can you have sex with a hepatitis patient if you have vaccinated?

Hepatitis: First you must know that there are several different types of hepatitis. Only two of them can be vaccinated for. So, your question is missing the most important part of your question. Hepatitis a and b can be vaccinated for. The other common deadly hepatitis in america, hepatitis c, cannot be vaccinated for but is rarely--if ever--transmitted sexually. Hepatitis d, e, f, g and h are not common.

Maybe yes, maybe no: What kind of hepatitis is it? Without knowing that, you get blood test to check your status for hep a, hep b, and maybe hep c. If not immune, then you can get the hep a and hep b vaccines, but there is no vaccine for hep c or other hepatitis. Later, get another blood test to make sure the hep b vaccine worked (if the partner is a hep b carrier, or if you are in a high risk group or occupation).
