That's a really thoughtful question, and it makes sense to want to understand why a vaccine is being recommended alongside treatment.
Darzalex can cause a dormant hepatitis B virus to become active again — even in people who had it in the past and didn't know it. This is why doctors take it seriously as a precaution. Here's what typically happens around this:
- Before starting Darzalex, doctors screen for any signs of hepatitis B infection
- During treatment, monitoring continues to watch for any reactivation
- After treatment ends, monitoring carries on for a period of time as well
The hepatitis B shot your doctor suggested is likely a protective measure to reduce the risk of reactivation while your immune system is being affected by treatment.
It's always worth asking your doctor to walk through the reasoning — they can confirm whether it's for prevention or based on something found in your screening. Never a bad question to ask!
