Vaccine-preventable diseases (VPDs) are diseases that are preventable through the use of immunizations. Immunizations are the most effective method for protecting the community against VPDs.  However, these diseases still occur because of importation, vaccine failure or disease breakthrough, and incomplete or no vaccinations.

In 2018, hospitalized influenza was the most commonly reported VPD with 178 cases (65.7%), followed by pertussis with 37 cases (13.7%), chickenpox with 24 cases (8.9%), hepatitis B with 23 cases (8.5%),  hepatitis A with six cases (2.2%), and mumps with three cases (1.1%).
