Vaccination Schemes - Persons with High Risk Conditions


Seasonal influenza vaccination is one of the effective means to prevent seasonal influenza and its complications together with reduction in influenza related hospitalisation and death. The Scientific Committee on Vaccine Preventable Diseases recommends persons with chronic medical problems as priority group to receive seasonal influenza vaccination every year, as they have a higher risk of suffering from severe influenza.

To encourage people to receive seasonal influenza vaccination, the Government will provide free or subsidized seasonal influenza vaccination to the following eligible persons: 

The following Hong Kong Residents Available Scheme / Programme Details of Service Provider Government Subsidy / Free
