Okay kiddo, so you know that there are many medicines and drugs that people take when they are sick or hurt, right? The European Federation of Pharmaceutical Industries and Associations (EFPIA for short) is like a big group of grown-ups who work together to make sure these medicines are safe and effective.
They help the companies that make medicines to talk to each other and share information so that they can make better medicines. They also make sure that these medicines are available to people who need them, and they work with doctors and scientists to make sure that the medicines are used correctly.
Think of it like a big team of superheroes who work together to make people feel better when they are sick. The EFPIA helps these superheroes work together so they can be even better at fighting the bad guys (in this case, sickness and disease).
