Okay kiddo, so imagine there are some really important rules grown-ups made for making and selling medicine. These rules are called "regulations" and they help keep people safe and healthy when they take medicines.
But sometimes the rules they make can actually make it hard for companies to make certain medicines. This is especially true for medicines that are for really rare diseases. That's where the term "Euro-orphan" comes in.
"Orphan" refers to a rare disease, which means it doesn't happen to very many people. And "Euro" is short for "European" because the rules we're talking about apply in European countries.
So, when we put "Euro-orphan" together, it means a medicine that treats a rare disease, and it's made in Europe. But since it's so hard for companies to make these medicines, the government put some special rules in place to help them. These rules give special incentives to companies that create medications for rare diseases.
These incentives can make it more appealing for companies to take on the challenge of making these medicines, and they can also help make the medications more affordable for people who need them.
So, the term "Euro-orphan" refers to a very important effort to make sure people with rare diseases have access to the medicines they need to stay healthy.
