The Public Health Ministry insists the Sinovac vaccine is safe and it will continue to use it, despite seven people having problems after receiving it.

The ministry's announcement came after a doctor at Chulalongkorn University revealed on Facebook on Tuesday that seven people had suffered stroke-like symptoms after being given the Chinese company's jab.

Officials say all seven -- six in Rayong and one in Chon Buri -- regained full health after doctors gave them medication to dissolve blood clots.

Dr Taweesap Siraprapasiri of the Department of Disease Control said six of the people -- five medical workers and a hospital employee, all in Rayong -- had pre-existing conditions before receiving Sinovac's vaccine CoronaVac.

Dr Taweesap said they'd all been given a shot of CoronaVac between April 5 and 9.

All fully recovered in 1-3 days.

"We think that the symptoms were linked with the inoculation because they happened [just] 5-10 minutes after their injections," a doctor from Siriraj Hospital said.


Public Health Minister Anutin Charnvirakul said that the government would not stop its Sinovac vaccination programme.
