The alleged move by the medical group, which offered services such as prepaid inoculation packages and body checks, prompted the government to set up a task force.
On Tuesday, Chief Executive John Lee warned that people linked to the suspected shutdown of the clinics would be held accountable.
He also said the Commerce and Economic Development Bureau will review existing laws and submit a report as soon as possible.
“The government will examine whether the existing regulations are adequate, particularly for prepaid consumption, and consider various proposals, including the introduction of a statutory cooling-off period, limiting the maximum contract period, and addressing industry operational conditions,” Lee said.
He said customs and police officers will probe the incident, while the Consumer Council will exercise its authority to safeguard the rights of customers.
The authorities are offering “feasible assistance” to affected individuals by allowing children who are eligible to get their remaining vaccinations at government health centres, Lee added.
