The jab stations will reopen on June 28 after measures are implemented to improve efficiency of services, authorities said.
A total of 174,193 people had received jabs at the 45 stations from June 7-10, according to Social Security Office (SSO) spokesperson Nantachai Panyasurari. However, that figure fell short of the target of 200,000 people or 50,000 per day.
He blamed the shortfall on unsuitable conditions and incomplete information.
For instance, some people were rejected by vaccination staff because their body temperature or blood pressure was high due to hot weather, or their information submitted by organisations was missing, said Nantachai.
"Hence, we decided to improve services at all vaccination stations in a bid to ensure maximum efficiency," he added.
