How do mRNA vaccines protect us from viruses?

An mRNA vaccine is like giving your body a map to build its own superhero team against viruses.

mRNA stands for messenger RNA, and it's like a set of instructions that tells our cells how to make proteins, the building blocks of our body. When we get an mRNA vaccine, it gives our body a copy of these instructions so it can create a protein found on the surface of the virus.

Once the body gets the instructions from the vaccine, special cells inside our body read them and start making proteins that look like parts of the virus. This helps our immune system recognize those proteins as not belong, like spotting a fake friend in a crowd.

Then, the immune system starts training to fight off the real virus if it comes along later. It’s like practicing for a test so you know exactly what to do when the real challenge arrives.

Because of this, your body is ready to stop the virus from making you sick, without ever having met the virus before!
