COVID-19: AstraZeneca defends vaccine as Thailand joins countries to suspend jabs over blood clot fears AstraZeneca insists that its coronavirus vaccine is safe - and the company has the backing of the UK and European drug regulators. Thailand has said it will delay use of the AstraZeneca COVID-19 vaccine after several European countries temporarily suspended the jabs following a small number of reports of blood clots.

Officials have insisted the delay, pending an investigation into the cause of reported side-effects, will not have a big impact on the country's rollout.
