Government increases interval between AstraZeneca vaccine doses to 16 weeks

The Public Health Ministry said on Monday it is adjusting its Covid-19 vaccination plan to administer first jabs to as many people as possible due to the current outbreak.

“We decided to increase the interval between AstraZenecca vaccine doses from 10 weeks to 16 weeks. This means those who get their first jabs in June will get their second jabs in October,” ministry permanent secretary Dr Kiattiphum Wongrajit said.

“There is also an academic research that says such a move will improve the recipients’ immunity.”

Regarding the rumours that the increase in gap between doses is due to the government's inability to import enough vaccines in time for the second jabs, he said they had already discussed this new plan with the manufacturer and they have promised to deliver the vaccines accordingly starting from June.

“In June the ministry will order an additional 3 million doses of Sinovac vaccine to be provided alongside the AstraZenecca vaccine,” Dr Kiattiphum said.

“People can rest assured that the ministry is still following the goal of providing vaccination to all citizens to create herd immunity against Covid-19,” he added.
