Ocrevus and travel vaccinations

My wife is just about to start her first Ocrevus, next week. Then will have another dose in late September. We are hoping to travel to Africa in August, so will require Hep A and Tetanus vaccinations. They’re both non-live and the first Ocrevus infusion will have been 4 months ago by the time she gets any jabs, so will that be OK? Or can you just not have any vaccines like these while you’re on the Ocrevus programme? Has anyone experienced this? Obviously will as doctor too but would be grateful for any thoughts. Thanks

A Question for your doctor I THINK.

I had to have yellow fever vaccine for kenya which was some years ago, boy that was rough.
but i would check with the neurologist.
