Vaccines that Malaysia received from Europe have already been administered, an adviser to Science, Technology and Innovation Minister Khairy Jamaluddin told DAP secretary-general Lim Guan Eng.

"It's in the arms of Malaysians," tweeted Mohd Ghows Azzam, who is Khairy's science adviser.

He was responding to Lim's query on what happened to five million doses of vaccine that Europe claims to have delivered to Malaysia.
