Is Covishield an mRNA vaccine?

mRNA vaccines deliver messenger RNA that cells use briefly to make an immune-training protein. Covishield uses a modified adenovirus as a carrier for genetic instructions. The carrier is designed not to replicate in the body. Both approaches aim to teach the immune system to recognise a target, but they use different delivery systems and should not be described as the same vaccine technology.

Tell the vaccination team about previous vaccine reactions, severe allergies, current illness, pregnancy, immune conditions, and medicines. Bring details of earlier doses if available. Ask which product is being offered, whether it matches your recommended schedule, and what observation period is advised afterwards. A vaccine information sheet can help you review expected short-lived reactions.

Get urgent help for trouble breathing, swelling of the face or throat, widespread hives, collapse, or sudden severe weakness after vaccination. Contact a clinician about symptoms that are severe, unexpected, or not settling, and report the timing and dose received. Mild soreness, tiredness, headache, or fever can occur as the immune system responds.

Ask which platform your scheduled vaccine uses, why it is recommended for you, and how your previous doses affect the plan. Check what to do if you have an allergy history or take treatment that affects immune responses.
