Hepatitis A and B vaccine schedule for adults

Hepatitis A and hepatitis B are different infections, so protection against one does not automatically protect against the other. The schedule depends on the product, your age, previous doses, travel or work exposure, medical conditions, and how soon protection is needed. A clinician may recommend a routine course or an accelerated plan, followed by later doses when required. Keep a written record of vaccine names and dates.

Tell the vaccinator about earlier hepatitis vaccines, pregnancy, immune-system problems, allergies, and any current illness. Bring your vaccination record if available. If a dose is late, contact the clinic; many courses can continue without restarting, but the next date should be chosen professionally. After vaccination, remain for the clinic’s observation period and expect possible short-lived soreness or tiredness.

Seek emergency help for trouble breathing, swelling of the face or throat, widespread hives, collapse, or severe dizziness after vaccination. Contact a clinician for persistent high fever, worsening illness, or symptoms that concern you. Dark urine, nausea, poor appetite, and feeling generally unwell can also occur with liver illness and should not be assumed to be a vaccine reaction.

Ask which infections your vaccine covers, how many doses your product requires, whether you need an accelerated schedule, and what to do after a missed appointment. Discuss whether testing or a liver function test is relevant to your medical situation.
