Ministry of Health spokeswoman Or Vandine urged the public not to discriminate among the different Covid-19 jabs available, saying they had all undergone thorough studies and clinical trials before being put into use.

Vandine, who is also head of the national Covid-19 vaccination committee, made the remarks on August 26 after Prime Minister Hun Sen hinted that the Chinese-made Sinovac and Sinopharm vaccines would be the main jabs used as booster doses as the government had sufficient supplies of them.

To date, the government has used the AstraZeneca vaccine as a booster dose for frontline workers including medical and military personnel and those most at risk in the provinces on the Cambodian-Thai border.

“The vaccines all share similarities. I've noticed that some of our people seem to discriminate against a particular make of vaccine. We should not, because before any vaccine is introduced for public use, it would have undergone thorough research and tests,” she said.

As of August 26, Cambodia had vaccinated 88.74 per cent of the targeted adult population of 10 million and 66.21 per cent of the 12-17 age group of nearly two million.

The Covid-19 vaccination commissions have also administered booster doses to 560,000 people.
