Thailand’s health ministry said on Sunday more than 600 medical workers who received two doses of China’s Sinovac vaccine have been infected with Covid-19, as authorities weigh giving booster doses to raise immunity.
Of the 677,348 medical personnel who received two doses of Sinovac, 618 became infected, health ministry data from April to July showed. A nurse has died and another medical worker is in critical condition.
An expert panel has recommended a third dose to trigger immunity for medical workers who are at risk, senior health official Sopon Iamsirithawon told a news briefing on Sunday.
“This will be a different vaccine, either viral vector AstraZeneca or an mRNA vaccine, which Thailand will be receiving in the near term,” he said, adding that the recommendation will be considered on Monday.
The announcement comes as the Southeast Asian country reported a record high of 9,418 community infections on Sunday.
