The TGA (Therapeutic Goods Association) have provided an update regarding the AstraZeneca COVID-19 vaccine in light of preliminary reviews by the European Medicines Agency (EMA) and United Kingdom Medicines and Healthcare products Regulatory Agency (MHRA), regarding the risk of blood clots in people who have received the AstraZeneca COVID-19 vaccine.
The findings of these reviews are that the benefits of the vaccine continue to outweigh the risks. The EMA’s safety meeting noted that the number of people with blood clots in large clinical trials and who have received the vaccine in global rollouts were less than is expected in the general population. 20 million people have received the vaccine in Europe and several more million in other parts of the world.
They noted there have been a very small amount of people who have experienced very rare clotting conditions – disseminated intravascular coagulation (DIC) with thrombocytopenia; and cerebral venous sinus thrombosis (CSVT). A causal link with the vaccine has not been established and these conditions are also seen in the general population.
Both the EMA and the MHRA are continuing to review cases of these rare clotting conditions.
The TGA has not received any reports of blood clots following vaccination with the AstraZeneca COVID-19 vaccine in Australia (as of 18 March 2021) and advise people to continue to receive the vaccine when eligible. Monitoring of the safety of this vaccine will continue and if there are any safety concerns these will be communicated to the public.
