Vaccination has reduced the disease burden of infectious disease since it was invented. Each person has his or her own unique vaccination needs during the various stages of one’s life. What each one needs is determined by one’s health, age, lifestyle and occupation at that time. Strategically, the Centre for Disease Control (CDC) Advisory Committee on Immunization Practices (ACIP) introduced a simple HALO2 approach to help physicians customise vaccinations for the public with the circumstances and needs of the public in mind. With the HALO approach, the public is able to discuss with their personal family physician or general practitioner and receive the relevant vaccines to prevent diseases and maintain health.
