The term "vaccination schedule" refers to a plan or timetable for administering vaccines to an individual. This typically involves receiving multiple doses of a particular vaccine at specific intervals, with the goal of building immunity against a particular disease over time. The schedule is designed based on factors such as age, health status and the type of vaccine being given. It takes into account that different vaccines require different numbers of doses to be effective, and that some vaccines are more effective when administered at certain ages or in combination with other vaccinations. The goal is to ensure that an individual receives all necessary vaccinations according to the recommended schedule for optimal protection against preventable diseases.
