What’s in a vaccine?
Most vaccines contain a small amount of bacteria, virus or toxin that has been weakened or destroyed in a laboratory first. Some contain chemicals that make your body think it’s coming into contact with bacteria, virus or toxin. This means there’s a very low risk of healthy people catching a disease from a vaccine. It’s also why you might see vaccines being called “live” or “non-live”.
Differences between live and non-live vaccine:
Live (weakened) vaccines contain viruses or bacteria that have been weakened, cannot be given to people with a weakened immune system and give long term protection.
Non-live (destroyed) vaccine contain viruses or bacteria that have been destroyed, can be given to people with a weakened immune system and often needs several doses or a booster vaccine for full protection.
