Vaccination requirements refer to the rules set by governments, schools, or employers that mandate individuals to receive certain vaccines. These requirements are often in place to protect public health by preventing the spread of infectious diseases, such as measles or COVID-19. In many cases, individuals may need to show proof of vaccination before attending school, traveling, or starting a new job. Exemptions may be available for medical, religious, or philosophical reasons, but these vary by location and organization. Understanding these requirements is essential for compliance and community safety.
