The drug regulator said 30 of the 18.1 million people in the UK who had the Oxford vaccine developed blood clots.
The Medicines and Healthcare Products Regulatory Authority (MHRA) confirmed that seven of these 30 people had died as of March 24.
The UK regulator said there is currently no evidence to suggest a causal link between blood clots and blood clots. Oxford fistand that the benefits continue to outweigh any risks.
Investigations are underway to determine if there is a link or whether the cases are coincidence.
MHRA’s chief executive officer, Dr. June Raine said: ” COVID-19 The AstraZeneca vaccine continues to outweigh any risks in preventing COVID-19 infection and its complications, and the public should continue to receive their vaccines when invited. “
MHRA said Thursday There are “22 reports of cerebral venous sinus thrombosis (CVST) and 8 reports on other thrombosis events with low platelets”.
The figures cover December 9, 2020 through March 21, and approximately 2.2 million second doses this year, when 15.8 million doses of the AstraZeneca vaccine were administered.
Concerns about blood clots have grown after very few cases have occurred in the tens of millions of cases who received the Oxford-AstraZeneca vaccine.
Some countries, such as Germany, have limited its use to certain ages, but the European drug monitor and the World Health Organization both safe and effective.
The British Society of Hematology has published a new guideline for doctors amid concerns that cases of blood clots may be linked to a condition known as thrombocytopenia.
It includes patients with low numbers of platelet cells in their blood that are necessary for clotting.
“A team of experts from our peers has recently been involved in the diagnosis and management of a rare thrombosis syndrome associated with low platelets, which has been reported in several cases.
“Currently, no causal relationship has been established with coronavirus vaccination.
“However, if you spot patients with this syndrome close to coronavirus vaccination, it is very important that you complete the online yellow card – this will trigger a request from the MHRA for more details.”
In March, the MHRA said anyone who had a headache that lasted more than four days after the vaccine or had bruising outside the site of the vaccine a few days later should seek medical attention.
However, he added that headaches are part of the flu-like symptoms, one of the most common side effects of the vaccine, but these should normally go away within a day or two.
To date, 31,301,267 people have received the first dose of vaccine in the UK and 4,948,635 people received two doses of vaccine.
