He said Deputy Prime Minister Prawit Wongsuwan had urged the ministry to improve efficiency of services as soon as possible.
"[Public Health Minister] Anutin and I are working closely in order to effectively contain the spread of Covid-19," he said.
He expected all vaccination stations to reopen on Monday.
A total of 174,193 people had received jabs at the 45 stations from June 7-10, according to Social Security Office spokesperson Nantachai Panyasurari.
The figure, however, fell short of the target of 200,000 people or 50,000 per day.
