Chronic conditions weaken the body's ability to fight infection and make complications worse, so these vaccines matter more than for the general population.
Seasonal flu vaccine
People with chronic illness are more prone to serious complications from flu, such as pneumonia and worsening of their existing condition. A yearly flu vaccine is a subsidised item under the Hong Kong government programmes, and people with diabetes, heart disease and other chronic conditions can get it free or subsidised.
Pneumococcal vaccine
Pneumococcus can cause pneumonia and invasive infection, and people with chronic illness are at higher risk. The government programme subsidises pneumococcal vaccination for eligible high-risk people. Which vaccine and what schedule depend on your age and health, as assessed by a doctor.
COVID-19 vaccine
COVID-19: check the official priority-group conditions for age, health or occupation. The clinical booster recommendation and an open vaccination service are separate matters; government service is currently suspended, as explained in the service notice below.
Before vaccination
Recommendations differ by condition and how well it's controlled. Which vaccines suit you, in what order, and whether you qualify for a subsidy are points to confirm with your family doctor or specialist.
Check COVID-19 service availability separately
Service check, 17 October 2026: CHP still reports a temporary suspension of the government COVID-19 vaccination service after the LP.8.1 supply expired. An expected resumption in the fourth quarter is not a confirmed reopening date. Check the official notice and provider for current service, formulation and supply.
