Why are mRNA vaccines being developed for non-infectious diseases?

Sometimes, scientists use mRNA vaccines to help our bodies fight not just germs, but also other problems that aren't caused by infections.

Think of your body like a superhero training camp. Normally, vaccines teach your body how to recognize and beat bad guys (like viruses). But sometimes, there are other challenges, like a tough opponent who isn’t trying to make you sick, but is causing trouble in another way.

That’s where mRNA vaccines can be really useful. Instead of fighting germs, your body gets practice for something else, maybe a condition that happens when things inside the body don't work quite right. It's like getting ready to fight a new kind of opponent by learning their moves in advance.

Instead of fighting viruses, you might be training for something else, like a disease caused by unhealthy cells or bad cholesterol. This helps your body become stronger and better prepared for these other kinds of problems.
