Hong Kong's health authorities have issued a warning against arbitrarily altering children's vaccination schedules without reliable scientific data or medical research support, stating that doing so poses severe and irreversible health risks to children. The advisory was released by the Department of Health on August 12, 2026.
The statement emphasizes that vaccination schedules are carefully designed based on extensive research and epidemiological data to provide optimal protection at the most vulnerable stages of a child's development. Deviating from these schedules without medical guidance could leave children susceptible to preventable diseases.
Health officials urge parents to consult healthcare professionals before making any changes to their children's vaccination plans. They also remind the public that vaccines are rigorously tested for safety and efficacy before approval.
The warning comes amid growing global concerns about vaccine hesitancy and misinformation. Hong Kong's Centre for Health Protection continues to monitor vaccination coverage and encourages timely immunization to maintain herd immunity.
