China's Hong Kong Special Administrative Region asked the drugmaker AstraZeneca to delay the delivery of its COVID-19 vaccine, the city's Secretary for Food and Health Sophia Chan said Friday, adding that Hong Kong has enough supply of COVID-19 vaccines.

The city is now looking to get vaccines that can protect against new coronavirus variants, Chan said.

The decision was made following news that the European Medicines Agency (EMA) found a possible link between the AstraZeneca vaccine and rare blood clotting issues in adults who had received the shot.
