While vaccines are recommended for almost everyone, there are specific groups of people who may be particularly vulnerable to severe forms of vaccine-preventable diseases. Their health conditions may increase the risk of developing complications requiring hospitalisation, developing secondary illnesses or even dying. Therefore, it is imperative to actively promote vaccination to those groups to ensure that they receive all the vaccines that are suitable for their age and clinical situation. Pharmacists can play an important role in promoting and advocating vaccination to these groups by leveraging their accessibility, expertise and trust by the population. Their frequent interactions with the public provide valuable opportunities to raise awareness of the importance of vaccination.
