Australia investigates possible link of blood clot case to AstraZeneca vaccine

Green light for AstraZeneca vaccine supplied through Covax

"On the basis of this ongoing review, the benefits of the vaccines against Covid-19 continue to outweigh any risks and you should continue to get your vaccine when invited to do so", the MHRA said.

The rising number of blood-clot cases and the growing moves to suspend or limit shots have added to the uncertainty around the AstraZeneca vaccine, which many countries around the world were relying on for their immunization programs.

The British Medicines Regulatory Authority announced Friday that it has registered 30 rare cases of blood clotting in Britain among more than 18 million people who received the AstraZeneca vaccine.

"The TGA has received only one report of a case of thrombosis and thrombocytopenia following vaccination with the AstraZeneca vaccine in Australia but the causal link has not yet been established".

Australia has been highly successful in curbing the virus with snap lockdowns, border closures and swift tracking, reporting just under 29,300 infections and 909 deaths.

Prof Kidd said expected side effects from either the Pfizer or AstraZeneca vaccines could include fever, sore muscles, tiredness and headache and that such symptoms could start about 24 hours after receiving the vaccine and last one to two days.

The committee is expected to come with further information about the AstraZeneca vaccine.

"We are taking this very seriously", Professor Kidd said on Friday afternoon.

He emphasised the risk of Australians contracting COVID-19 was "far greater" than contracting the rare blood clotting disorder.

Lareb said the events had occurred 7 to 10 days after vaccination.

Some countries have restricted use of the AstraZeneca vaccine while others have resumed inoculations, as investigations into reports of rare, and sometimes severe, blood clots continue. The vaccine received conditional approval on March 2.

Out of the 18 million people vaccinated across the United Kingdom up to March 24, 30 had presented with the blood clots.

In a statement, the government said there had been five reports of thrombosis and abnormally low platelets, which help blood clot, in women aged 25 to 65 (around 400,000 AstraZeneca injections have been given in the Netherlands, according to the same government statement).
