To minimise the risk of serious complications or death after COVID-19 infection, those at high risk, particularly the elderly and persons with underlying comorbidities, should receive a free JN.1 vaccine booster dose as soon as possible if they have received their last dose or had COVID-19 infection more than 6 months ago (whichever is later). Members of the public who have not received the initial dose(s) of the COVID-19 vaccine (including infants and children) should get free JN.1 vaccination as soon as possible.
Genetic analysis has shown that the predominant circulating strains in Hong Kong are still JN.1 and its related variants. The JN.1 vaccines currently used in Hong Kong can effectively prevent the related variant.
