Do you have to a jab when go secondary school?

The answer to your question depends on the country and region you are referring to. In some countries, such as the UK and the US, secondary school students are not required to have any specific vaccinations, including the jab you mentioned, while in other countries they may be required to have certain vaccinations before entering secondary school. However, it's important to note that vaccination requirements can change over time, so the best course of action is to check with the local health authorities or your child's school to confirm the specific requirements in your area.
