Twinrex did not give me immunity to Hep B
After paying a lot of money for the Twinrex shots, I found out I do not have immunity to Hep B! The family doctor said this happens in some people. The doctor knew of a patient in the same situation who got another full round of shots and still did not develop immunity. So, if u want to know for sure if u have immunity, u have to get tested.
