Home minister Hamzah Zainudin said the authorities were identifying provisions in the existing laws that can be used to act against them.

“If we find that the anti-vaccination groups are committing an offence, we will act.

“We will study the police reports to see which laws they have violated and the category of the offences, among others.

“I will be announcing the progress on this from time to time,” he told reporters after handing over food aid in a meet-and-greet session with Kampung Sungai Ara residents in Batu Kurau, near here today.

Asked if the government was considering drawing up a specific law to deal with anti-vaxxers, Hamzah said that will also be decided in due course.

It was reported yesterday that the health ministry had lodged several police reports against anti-vaccine groups which had spread false information about Covid-19 vaccination.

Its minister, Khairy Jamaluddin, via Twitter, said he hoped that follow-up action, including investigations and prosecution, could be expedited.

He said anti-vaxxers continued to spread false news, thereby threatening public health.
