Prime Minister Hun Sen, launching the vaccination campaign for those aged 12 to 17, said on Sunday (Aug 1) that the third dose will be offered to between 500,000 and one million front-line workers as a priority.

"People who have already been vaccinated with Sinopharm and Sinovac should be given AstraZeneca as the third booster dose," he said in a speech which was broadcast on social media.

"For Cambodians who have been vaccinated with AstraZeneca, Sinovac should be given as the third dose," he added.

Mr Hun Sen also said the country will purchase more AstraZeneca vaccines through the global Covax vaccine-sharing scheme for the booster shots and the recent United States-funded Johnson & Johnson vaccines will be used to vaccinate indigenous peoples in north-eastern Cambodia. ■
