The essential blood clots should be listed as a “very rare” side effect of the AstraZeneca vaccine against Covid-19, the European regulator confirmed on Wednesday, while it is estimated that the risk-benefit ratio remains “positive”.
Blood clots are a very rare side effect of the AstraZeneca vaccine against Covid, which the European Medicines Agency (EMA) confirmed on Wednesday.
For their part, UK health officials said they had observed the deaths of 19 people who received Oxford / AstraZeneca out of a total of 79 identified cases of blood clots, and also ensured that the benefits of its use remained greater than the dangers posed.

What the Anglo-Swedish laboratory AstraZeneca did not do without on Wednesday was based on the conclusions of both the British Medicines Agency (MHRA) and the European Medicines Agency (EMA).
For the latter, which is headquartered in Amsterdam, “Unusual blood clots associated with low blood platelets should be listed as very rare side effects” by AstraZeneca. However, no specific risk factors such as age, gender, and medical history were identified, noted Emercooke, EMA executive director.
“A plausible explanation for these rare side effects is an immune response to the vaccine,” added Cooke, recalling that the vaccine is “very effective” and “saves lives”.
“Plausible but not confirmed”
A connection between AstraZeneca and the occurrence of a rare form of blood clot is “plausible but not confirmed,” for its part ruled the World Health Organization on Wednesday.

“Special studies are needed to fully understand the possible relationship between vaccination and possible risk factors,” said WHO specialists.
They also note that “although worryingly, these phenomena are very rare,” more than 200 million people have received this vaccine.
The scientific committee overseeing the Covid vaccination campaign in the UK has recommended that the use of AstraZeneca be restricted to people over 30 years of age where possible.
“Adults between 18 and 29 years of age who do not have comorbidities that are at higher risk of developing a severe form of Covid-19 disease should be offered another Covid-19 vaccine in place of the vaccine. AstraZeneca, if such an alternative Solution is available, “said Prof. Wei Shen Lim, JCVI, insisting that the committee did not recommend that vaccination be discontinued in any age group.
Belgium has also been cautious in the decision to reserve the AstraZeneca for more than 55 years, while the Castile and León region in northwestern Spain has ceased its use for Denmark altogether.
Some other countries in the European Union, such as France and Germany, had already decided not to give this vaccine under a certain age. On this subject, the EU Health Commissioner Stella Kyriakides called on the 27 EU member states to speak “with one voice” about AstraZeneca in order not to stir up suspicion.
Neither of these countries had achieved their target of vaccinating 80% of people over 80 by the end of March, the commission regretted. AstraZeneca’s vaccine is one of four vaccines approved in the EU, along with the vaccine from Moderna, Pfizer / BioNTech and Johnson & Johnson, which is expected to ship on April 19th.
The UK has also announced that it will use the vaccine from the American laboratory Moderna. “We ordered 17 million cans of it,” Prime Minister Boris Johnson tweeted.
The Moderna vaccine launch begins today with Carmarthen in Wales. We have ordered 17 million cans that will fire across the UK in the coming weeks.

In the United States, vaccination is “in full swing,” said President Joe Biden, assuring that from April 19, all American adults will be eligible for vaccination.
According to the authorities, the United States is absolutely the most severely affected country by the pandemic, with more than 550,000 dead. Over the past seven days, an average of more than three million injections were given each day.
