Is COVID-19 vaccination done with an mRNA vaccine?

An mRNA vaccine delivers temporary instructions that help the body recognise a target from the virus. Cells use those instructions to make a small amount of the target protein, then the instructions are broken down. The vaccine does not contain a live coronavirus and does not change a person's genetic material. Protection develops through the immune response, which can include temporary soreness, tiredness, headache, fever, or muscle aches.

Tell the vaccinator about previous vaccine reactions, allergies, pregnancy, immune conditions, and medicines. Check which product and dose are being offered and follow the recommended schedule for your situation. Remain at the vaccination site for the observation period advised by staff. Mild short-lived symptoms can occur; rest and fluids may help, while medicine should be used only as directed.

Seek urgent medical care for trouble breathing, swelling of the face or throat, widespread hives, fainting, or severe chest pain after vaccination. Contact a clinician for symptoms that are intense, persistent, or worrying, including palpitations or unusual weakness. A clinician can distinguish an expected reaction from a problem needing assessment.

Ask whether the offered product is an mRNA vaccine, why it is recommended for you, and which side effects should prompt contact. Discuss timing if you are acutely unwell, have had a previous reaction, or take treatment that affects the immune system.
