One of the many vaccines that are being used worldwide to provide a modicum of safety to the public is the AstraZeneca vaccine. However lately reports show that those who have taken the AstraZeneca vaccine experience blood clots as a side effect. The Medicines and Healthcare products Regulatory Agency (MHRA) released a statement in which it detailed 22 reports of cerebral venous sinus thrombosis (CVST).
AstraZeneca Vaccine Provides A Modicum Of Safety To The Public
In these cases, clots form in the sinuses that drain blood from the brain. There have also been eight reports of thrombosis submitted to the agency. These cases occur out of a total population of 15.8 million people who have received the AstraZeneca vaccine. Despite these side effects, the agency has advised that people of all age groups should receive the vaccine.
Their reason for this is that blood clotting is very rare and the chances of one experiencing blood clots after taking the vaccine are small. They argue that the benefits of the AstraZeneca vaccine easily overshadow the dangers. This opinion is the same as that of the European Medicines Agency (EMA) as well as the World Health Organization (WHO).
Several countries have reported cases of blood clots occurring once people have taken the AstraZeneca vaccine. Some have decided to stop administering the vaccine altogether while other countries believe it’s in their citizen’s best interest to administer the vaccine only to certain age groups.
A spokesperson of AstraZeneca said, “Patient safety remains the Company’s highest priority.” The spokesperson urged WHO officials, as well as UK and EU representatives to continue to administer the vaccine. The AstraZeneca spokesperson also said that “The benefit-risk profile of the vaccine was reaffirmed in the EMA’s monthly safety update.”
Scientists are taking a closer look at the blood clots and what they believe is causing the blood clots in certain people. They are attempting to figure out the types of clots that are occurring. Cerebral Venous Sinus Thrombosis or CVST is an extremely rare occurrence. Experts are trying to determine whether Cerebral Venous Sinus Thrombosis is occurring as a result of the AstraZeneca vaccine or naturally.
So far the MHRA or the Medicines and Healthcare products Regulatory Agency have administered at least one dose of the vaccine to 15.8 million people. 30 cases of CVST have emerged in just the United Kingdom. The chances of patients getting blood clots in the brain or Cerebral Venous Sinus Thrombosis is 1.89 in a million.
“So the absolute risk of CVST after this vaccine remains extremely low and it’s not clear if this is any higher than the usually expected incidence of CVST,” stated David Werring from UCL Institute of Neurology. Normally these types of blood clots have a 5 to 15 chance in every million of occurring explained Werring. He did add that it is hard to tell as it is especially difficult to diagnose those cases.
Evidence suggests that blood clots after vaccination have strange features. Patients who experience blood clots after vaccination strangely show symptoms of thrombocytopenia which is a low count in the blood platelets that are necessary to prevent clotting. Based on this data Werring said, “This raises the possibility that the vaccine could be a causal factor in these rare and unusual cases of CVST, though we don’t know this yet, so more research is urgently needed.”
In America, the vaccines available to the public are the Pfizer vaccine, the Moderna vaccine, and the Johnson & Johnson vaccine. None of these vaccines seem to display any of the side effects that are a problem of the AstraZeneca vaccine. All three vaccines have proved beneficial in the fight against the Coronavirus and all its variants.
