If you have:
• Received the full course of Hepatitis B vaccine (3 doses)
• And developed protective antibodies (anti-HBs ≥10 mIU/mL)
Then, you are well protected, and the risk of infection is extremely low, even if you’re exposed.
If you’re unsure about your protection, you can do a simple blood test: Anti-HBs titre (to check your immunity level)
Hepatitis B virus can survive up to 7 days outside the body, especially in dried blood. So avoid sharing items like razors, toothbrushes, or nail cutters.

Dear Practo User.
Thanks for sending across your query.
After completing the Hepatitis B vaccine series, you're over 95% protected—even if you come in contact with an infected person. Hepatitis B virus can survive outside the body for up to 7 days, but with vaccination, your risk is extremely low. For further details kindly consult.
Next Steps
For further details you can consult with me in Dr. Monga medi clinic or consult me directly by taking a consultation on Practo.

Dear patient,
It’s good that you have taken the Hepatitis B vaccine after knowing your sister is Hepatitis B positive. The vaccine gives strong protection if you’ve completed the full 3-dose schedule. After full vaccination, your body develops antibodies that protect you from the virus in most cases.
Chances of infection after vaccination are very low, especially if your immunity (anti-HBs levels) is good. You can even check your anti-HBs antibody titer through a simple blood test to confirm your protection.
Hepatitis B virus (HBV) can survive outside the body on surfaces for up to 7 days, especially in dried blood. So, avoid direct contact with her blood, open wounds, or bodily fluids.
Always follow hygiene precautions at home:
• Do not share razors, toothbrushes, or nail cutters.
• Clean any blood spills using gloves and disinfectants.
Health Tips
If you’ve taken all vaccine doses, your risk is minimal — no need to panic. Just maintain basic hygiene and get your anti-HBs titer tested if you are concerned.
Let me know if you need guidance on that test.
Take care wishing you a speedy recovery!

Hepatitis B spreads through Blood or Body fluids or Sexual Contact and not through touching or mere physical contact.
So don't worry.You are not likely to get Hepatitis B just by touching her or being near her.
If you have any doubt you can discuss with your doctor.
