AstraZeneca vaccine: the benefit-risk ratio remains very favorable despite everything


Adverse effects linked to the administration of the AstraZeneca vaccine against the Covid-19 remain very rare, and there is no justification for limiting its use, the European Medicines Agency said.

For the European Medicines Agency, there is no reason to restrict the use of the AstraZeneca vaccine

The committee ad hoc tasked with studying the link between the injection of AstraZeneca’s vaccine against Covid-19 and the formation of blood clots has just completed its work. Conclusion: these side effects remain very rare, to the point that, at the current stage of knowledge, it is not necessary to restrict the use of this vaccine or to issue new instructions.The European Medicines Agency’s Expert Committee on the Safety of Medicines has confirmed that the benefits of the AstraZeneca vaccine for the prevention of Covid-19 outweigh the risks and side effects ”, Said Emer Cooke, the executive director of the European Medicines Agency during a press briefing broadcast live on YouTube.

No specific risk factor could be identified on the basis of the available data. The committee therefore does not recommend any specific measures to reduce the risk “, For her part said Sabine Straus, head of the Committee on the Safety of Medicines at the European Medicines Agency.

AstraZeneca vaccine: monitoring of adverse effects remains essential

If the European Medicines Agency took an interest in the safety of the AstraZeneca vaccine against Covid-19, which is already being injected in many countries around the world, it is because 62 cases of thrombosis located in the brain and the abdomen and 24 cases of venous thrombosis have been reported in the European Union via the EudraVigilance device. In 18 of these 86 cases, the patient had died. The majority of these cases have been in women under the age of 60, and thrombosis developed within two weeks of the vaccine injection.

The European Medicines Agency nevertheless invites anyone who has just been vaccinated to watch for possible side effects during the two weeks following the injection: chest pain, inflammation localized in one leg, persistent abdominal pain, headaches. head, blurred vision and small red dots under the skin around the injection site. If these side effects appear, you should call your doctor.
