Hepatitis B and COVID-19 vaccine together

Vaccination plans depend on the product available, your age, previous doses, immune status, pregnancy status and any recent illness. A healthcare professional can give vaccines at one appointment or arrange separate appointments. Receiving more than one vaccine does not cause hepatitis B or COVID-19 infection. Mild soreness, tiredness or a short-lived fever can occur after vaccination and usually settles with simple care.

Tell the vaccinator about a previous severe allergic reaction to a vaccine or an ingredient, and about any current high fever. A delay may be advised in some situations, while a minor illness may not prevent vaccination.

Bring your vaccination record and explain which hepatitis B doses you have already received. Ask the clinic to record the date, product and injection site for every dose. Stay for the observation period recommended by the clinic, drink fluids and rest if you feel achy. For prevention details, see [Hepatitis B Vaccination](/treatments/preventive-care-and-vaccination/hepatitis-b-vaccination/) and [Hepatitis B](/conditions/hepatitis-b/).

If you have chronic hepatitis B, vaccination does not replace liver follow-up. Your clinician may still arrange blood tests or a [Liver Function Test](/treatments/diagnostics-and-screening/liver-function-test/).

Seek emergency care for trouble breathing, swelling of the face or throat, widespread hives, collapse or severe dizziness after vaccination. Contact a clinician for a high or persistent fever, severe headache, chest pain, or symptoms that concern you. Separately, persistent [Dark Urine](/symptoms/dark-urine/) or [Fatigue](/symptoms/fatigue/) can have many causes and should be assessed rather than assumed to be a vaccine reaction.

Ask which vaccine schedule applies to you, whether both vaccines can be given at the same visit, what to do if a dose is late, and which reactions require urgent help. Tell the clinician about allergies, pregnancy, immune conditions and medicines.
