The mandatory vaccination requirement can be seen as a limitation on the right to physical integrity, which is the right to be free from physical harm or invasive medical procedures. While individuals have the right to make decisions about their own bodies, this right is not absolute and can be limited in certain circumstances, such as when public health is at risk. Mandatory vaccination requirements aim to protect the health and safety of the population as a whole, and are justified by the principle of balancing individual rights with the common good. However, it is important for such requirements to be implemented in a way that respects individual autonomy and provides exemptions for those with legitimate medical or religious reasons for not being vaccinated. **

Ultimately, the decision to include titles in communication depends on the context and the level of formality required. **
