Will the hepatitis a vaccine protect someone from other forms of hepatitis?

No. The hepatitis a vaccine is given as a series of 2 injections over 6 months. Once it is given, a lab test can be performed to establish if it was successful. Once the blood test shows the presence of hepatitis a antibody in your blood you are immune from contracting hepatitis a only. There is also a vaccine available for hepatitis b but there is no vaccine available for hepatitis c.
