What is the duration of Hepatitis B?
Acute Hepatitis B infection usually resolves within six months. However, not all patients develop acute hepatitis B, meaning it can become prolonged or even chronic, requiring ongoing medical care and monitoring.
Is the vaccine possible in the post-exposure period?

What are the side effects of the Hepatitis B vaccine?
Most side effects are mild and include pain or redness at the injection site, fatigue, headache, or low-grade fever.
How should a vaccine be scheduled in adults?
The standard adult schedule is three doses at 0, 1, and 6 months. Condensed or accelerated schedules, such as four doses within 12 months, may be used in specific cases.
Can I get vaccinated at CVS?

How do I know if I'm immune?
Immunity is confirmed by a Hepatitis B surface antibody (anti-HBs) blood test. A level of ≥10 mIU/mL indicates sufficient protection.
What is the difference between Hepatitis B and Hepatitis C?
Hepatitis B is caused by a DNA virus and can be prevented with a vaccine, whereas Hepatitis C is caused by an RNA virus with no vaccine available. Their treatment approaches and long-term risks also differ.
Is the vaccine safe in pregnancy?
Yes. The Hepatitis B vaccine is considered safe during pregnancy and is recommended for women at risk to protect both mother and baby.
