Vaccine-Preventable Disease (VPD) Highlights

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

In 2016, hospitalized influenza was the most commonly reported VPD with 133 cases (61.6%), followed by Hepatitis B with 34 cases (15.7%), pertussis with 24 cases (11.1%), chickenpox with 23 cases (10.6%), Hepatitis A with one case (<1%), and mumps with one case (<1%).
