South Korea’s National Assembly has passed a new Vaccination Management Act that creates a standalone legal framework for vaccination policy and expands the way immunization records are managed. The Korea Disease Control and Prevention Agency said the law is intended to cover the full vaccination process more systematically as demand varies across age groups and attention to vaccine safety has increased.

The law broadens the definition of vaccination beyond vaccines covered by the national immunization program. It requires the KDCA to establish a five-year national plan, while local governments will prepare linked regional plans and a vaccination committee will review major policy decisions.

Private-pay vaccinations move into the record system

A major change concerns vaccination histories. Providers will be required to check a person’s existing record before vaccination and register the new dose afterward, including vaccinations paid for outside the national program. That should allow people to confirm a more complete vaccination history and obtain certificates regardless of whether a shot was publicly funded.

The law also creates formal procedures for reporting suspected quality problems with vaccines or similar products. Public health centers and contracted medical institutions will have reporting obligations, and the KDCA will be able to order measures such as suspending vaccination when necessary. It also provides a legal basis for monitoring disease burden, vaccination rates, immunity and vaccine effectiveness.

The new system will not take effect immediately. The law is scheduled to apply one year after promulgation, leaving time to define the registration process, reporting rules and links between national and local planning. How private-pay vaccination records are integrated into the system, and what new steps clinics must follow, will be among the most practical details to watch.
