Is it possible to have the vaccine against gastro that is typically given to children?

Yes, the best way to prevent getting the stomach flu is by washing your hands frequently and avoiding contact with people who have it. It's important to note that there isn't a specific vaccine for stomach flu in older individuals because it can be caused by different types of viruses, making it difficult to create a vaccine that targets them all. So, practicing good hygiene and avoiding sick individuals are the most effective ways to protect yourself from getting the stomach flu.
