I can't find my vaccination record, is it dangerous to have the twinrix vaccine if I have already been vaccinated against hepatitis?

Hello Sir,

It's a safe bet that you've received the hepatitis A and/or B vaccine in the past, given that it's been on the vaccine schedule for quite some time. That said, Twinrix™ is administered regardless of whether or not you have received doses of hepatitis vaccines in the past. This is especially true if there is any doubt about past vaccine coverage.

So, you can receive Twinrix™ without any problems!

Truly,

Alexandre Chagnon, pharmacist

It's a pleasure sir!
