PETALING JAYA: The Health Ministry has dismissed as untrue a claim that a video clip purportedly shows students having adverse reactions after receiving the Covid-19 vaccine.

       It said the clip being circulated on social media was an old one related to the March 2019 chemical pollution in Pasir Gudang, Johor.

       The incident then resulted in over 4,000 people falling ill and 111 schools in the district being temporarily closed.

       The public has been urged not to spread false information.

       The ministry also shared the link of the original video for the public's information.
