What should you know about the COVID-19 mRNA vaccine BioNTech?

An mRNA vaccine carries temporary instructions that prompt cells to make a harmless piece of the virus. Your immune system responds to that piece and builds a memory of it. The mRNA is then broken down; it does not alter your genetic material. Vaccination is designed to prepare immune defences before exposure, although vaccinated people can still become infected.

Tell the vaccinator about previous severe allergic reactions, current illness, pregnancy, immune conditions, or medicines that affect immunity. Stay for the observation period recommended at the vaccination centre. A sore arm, tiredness, headache, chills, or fever can occur for a short time. Rest, drink fluids, and use only symptom relief that is suitable for you. Keep the vaccination record and follow the schedule advised by your clinician.

Seek urgent medical help for trouble breathing, swelling of the face or throat, widespread hives, fainting, chest pain, or a fast or irregular heartbeat after vaccination. Contact a clinician if a reaction is severe, worsening, or not settling, or if you are unsure whether a new symptom is related to the injection.

Ask which vaccine schedule applies to you, whether your medical history changes the advice, which symptoms need attention, and how vaccination fits with medicines or other vaccines you may need.
