Stanowisko AstraZeneca po opinii EMA

Szanowni Państwo,
Po dokonaniu oceny zdarzeń zakrzepowo-zatorowych u osób, które otrzymały szczepionkę przeciwko COVID-19 AstraZeneca, Europejska Agencja Leków (EMA) podtrzymuje swoje wcześniejsze stanowisko dotyczące pozytywnego stosunku korzyści do ryzyka stosowania szczepionki. Badania przeprowadzone przez EMA i Medicines and Healthcare Products Regulatory Agency (MHRA) z Wielkiej Brytanii wykazały, że nie ma dowodów na zwiększone ryzyko wystąpienia zatorowości płucnej lub zakrzepicy żył głębokich (DVT) u osób szczepionych preparatem COVID-19 Vaccine AstraZeneca.
Pandemia COVID-19 to globalny kryzys zdrowia publicznego, który wywiera znaczny wpływ na zdrowie, społeczeństwo i gospodarkę. Wciąż pozostaje jednym z największych obciążeń dla systemów opieki zdrowotnej na całym świecie. Szczepionki przeciwko COVID-19 pomagają chronić przed zachorowaniem, co jest ważne zwłaszcza w przypadku personelu medycznego zajmującego się hospitalizowanymi pacjentami z COVID-19 i populacjami wysokiego ryzyka, takimi jak osoby starsze lub osoby z chorobami przewlekłymi. Na podstawie dokonanych analiz EMA stwierdziła, że korzyści płynące ze szczepionki AstraZeneca w zapobieganiu COVID-19, z powiązanym ryzykiem hospitalizacji i zgonu, przewyższają ryzyko działań niepożądanych.
Bezpieczeństwo pacjentów ma ogromne znaczenie dla AstraZeneca i dlatego ściśle współpracujemy z EMA i organami regulacyjnymi na całym świecie, aby zapewnić właściwe stosowanie szczepionki przeciwko COVID-19.

Z poważaniem,
 
Piotr Najbuk
Public & Government Affairs Director

UK and EU regulatory agencies confirm

COVID-19 Vaccine AstraZeneca is safe and effective

 

Today the Medicines Health Regulatory Authority (MHRA) and European Medicines Agency (EMA) reaffirmed the benefits of COVID-19 Vaccine AstraZeneca continue to far outweigh the risks.

Earlier today, the MHRA announced their review of the small number of thromboembolic events in over 11 million people who received COVID-19 Vaccine AstraZeneca in the UK. The UK regulator confirmed that the benefits of the vaccine in preventing COVID-19 far outweigh the risks, and people should continue to get vaccinated when asked to do so. Following the rigorous scientific review, the MHRA concluded there is no evidence that blood clots in veins are occurring more than would be expected in the absence of vaccination. A detailed review of five UK reports of a very rare and specific type of blood clot in the cerebral veins (sinus vein thrombosis) occurring together with lowered platelets (thrombocytopenia) is ongoing. This has been reported in fewer than one in a million people vaccinated so far in the UK, and can also occur naturally – a causal association with the vaccine has not been established.

Subsequently, the EMA’s Pharmacovigilance Risk Assessment Committee (PRAC) concluded there was no increase in the overall risk of blood clots (thromboembolic events) with COVID-19 Vaccine AstraZeneca. However, the PRAC also concluded that, for very rare cases of serious thromboembolic events with thrombocytopenia, a causal link with the vaccine is not proven, but is possible and deserves further analysis. Furthermore, there was no evidence of a problem related to specific batches of the vaccine or to particular manufacturing sites.

AstraZeneca will continue to work closely with health authorities to ensure the appropriate use of COVID-19 Vaccine AstraZeneca. The Company recognises and will implement the recommendations of the PRAC, including the update of the product information, whilst continuing to understand the nature and relevance of these events to ensure the safe delivery of the vaccine continues during this public health crisis. Analysis of AstraZeneca’s safety database on tens of millions of records for COVID-19 Vaccine AstraZeneca did not show that these events occurred any more commonly than would be expected in millions of people.

Ann Taylor, Chief Medical Officer, said: “Vaccine safety is paramount and we welcome the regulators’ decisions which affirm the overwhelming benefit of our vaccine in stopping the pandemic. We trust that, after the regulators’ careful decisions, vaccinations can once again resume across Europe.”

Patient safety remains AstraZeneca’s highest priority and the Company has robust processes in place for the collection, analysis and reporting of adverse events and these are shared with regulatory authorities around the world.

COVID-19 Vaccine AstraZeneca, formerly AZD1222

COVID-19 Vaccine AstraZeneca was co-invented by the University of Oxford and its spin-out company, Vaccitech. It uses a replication-deficient chimpanzee viral vector based on a weakened version of a common cold virus (adenovirus) that causes infections in chimpanzees and contains the genetic material of the SARS-CoV-2 virus spike protein. After vaccination, the surface spike protein is produced, priming the immune system to attack the SARS-CoV-2 virus if it later infects the body.

The vaccine has been granted a conditional marketing authorisation or emergency use in more than 70 countries across six continents, and with the recent Emergency Use Listing granted by the World Health Organization this accelerates the pathway to access in up to 142 countries through the COVAX Facility.
