After Egypt obtained 4 million doses, the AstraZeneca vaccine raises concern again


Represent Concentration of estrazinica One of the most important vaccines approved in Egypt, as it has obtained 4 million doses so far, among the millions of doses that Egypt has contracted to provide globally approved vaccines for the Egyptian citizen. Covid 19Recently, a new worrisome side effect of the AstraZeneca vaccine was recently raised, after it was proven that vaccination was associated with the emergence of A rare nerve disorder known as Guillain-Barre syndrome, to be added as a new effect of this vaccine.

This vaccine began to be used for the first time in December 2020, although it is the most widespread vaccine in the world, as it is used in 184 countries, followed by Pfizer vaccine in 125 countries, but the accusations against it are not compared to the other five vaccines .. (Pfizer, Moderna, Sinopharma, Sinovac, Johnson & Johnson ).

Recently, the European Union Medicines Regulatory Authority issued a circular, confirming that a rare nerve disorder known as “Guillain-Barre syndrome” has been added as a possible side effect of the Covid-19 vaccine “AstraZeneca”.

Last July, the agency listed the same syndrome as a “very rare” side effect of the “Johnson & Johnson” vaccine against Covid-19, which uses the same technology as the AstraZeneca vaccine.

Guillain-Barré syndrome is a rare autoimmune disorder that attacks and destroys the body’s own nerves. It is a disease of the peripheral nerves that gradually weakens or even paralyzes them. It often begins in the legs and sometimes ascends to the respiratory muscles and then the nerves of the head and neck.

The agency said that the relationship between Guillain-Barre syndrome and the vaccine caused 833 cases of 593 million doses reported by July 31, less than one in ten thousand.

“The European Medicines Agency’s Pharmacovigilance Risk Assessment Committee concluded that a causal relationship between Vaccine AstraZeneca and Guillain-Barré syndrome is at least a reasonable possibility,” the statement said.

In the United States, the US Medicines Agency warned last July of an “increased risk” of developing this Guillain-Barré syndrome in people who received the “Johnson & Johnson” vaccine against Covid-19.

The benefits of the vaccine outweigh the risks

While the US Medicines Agency confirmed that the benefits of the two vaccines (Estrzenica – Johnson & Johnson) far outweigh their potential risks.

On the other hand, the scientist who developed the AstraZeneca vaccine, Professor Sarah Gilbert, said that vaccines still provide a strong degree of protection a year after many people received two doses of the vaccine.

A British study concluded that the chances of infection with the Corona virus decreased sharply after receiving the first dose of the “AstraZeneca” or “Pfizer” vaccine.


It was found from tests conducted on volunteers who received the vaccine more than a year ago that they still enjoy strong immunity.

The Ministry of Health and Population had confirmed that all vaccines for the emerging corona virus in Egypt are effective and safe, and that “the effectiveness of the AstraZeneca vaccine after the first dose” reaches 79%, and works to protect against the risk of infection with the virus and alleviate symptoms.

The first accusation: the vaccine’s link to blood clots

In March, the European Medicines Agency denied the existence of a link between the vaccine and cases of clotting, noting that the cases of clotting for people who received the vaccine in the normal rates, in the same context, the World Health Organization confirmed that the benefits of the AstraZeneca vaccine outweigh its potential risks.

The second accusation: a rare blood clot

And last April, an official at the European Medicines Regulatory Agency confirmed a link between the AstraZeneca vaccine and cases of rare blood clotting observed after taking it.

The European Medicines Agency had made recommendations to the 27 member states of the European Union, which are the ones who make their own decisions regarding AstraZeneca vaccinations.
