Hungary said on Friday it would have to delay the vaccination of tens of thousands of people after a bureaucratic glitch disrupted its distribution of AstraZeneca’s Covid-19 shot, Reuters reports.

Around 74,000 people had been due to get a dose over the weekend but a government official said there had been a synchronisation error between public records and a list of those registered for shots.

“We will apologise to them in a text message,” Istvan Gyorgy, a state secretary in charge of the government’s vaccination working group, told an online press briefing.

The shots would be administered at a later date and plans were still on track to vaccinate 400,000 people over the coming week, he added.
