A review from Norway’s medicines agency showed four new cases of “serious blood clotting in adults”, while the European Medicines Agency (EMA) confirmed one person in Austria was admitted to hospital with a blockage of arteries in the lungs, also known as pulmonary embolism. They died 10 days after they were vaccinated, and another death involving blood clots was reported in Denmark around the same time. The EMA has, however, stressed there is “currently no indication that vaccination caused these conditions”, adding the AstraZeneca’s jabs continue to outweigh its risks.
Are blood clots dangerous?
A blood clot is a clump of blood that has transitioned from a liquid into a gel-like semi-solid state.
Clotting is a necessary process that can prevent you from losing too much blood in certain cases, like when you’re injured or have a cut.
But blood clots can be very dangerous, at times presenting a life-threatening situation to people who get them.
An immobile blood clot generally won’t harm you, but there’s a chance it could move and become dangerous.
Symptoms of a blood clot include in the leg or arm:
- Throbbing or cramping pain
Other symptoms can include sudden breathlessness, sharp chest pains which may be worse when you breathe in, and a cough or coughing up blood.
Your symptoms will depend entirely on the size of the clot. That’s why it could be that you don’t have any symptoms, or you may only have minor swelling in the calf without much pain.
If the clot is large in size, it means your whole leg could be swollen and you may experience extensive pain.
Although not common to have blood clots in both arms and legs at the same time, it can definitely happen, but your chances of a blood clot increase if your symptoms are only in one leg or one arm.
If a blood clot manages to break free and travels through your veins to your heart and lungs, it can get stuck and stop the blood from flowing.
This is a medical emergency at which point urgent assistance must be sought.
If you think there’s even a chance you may have a blood clot, then call your GP or hospital doctor immediately.
A healthcare professional will be able to take into account your symptoms and medical history in an effort to let you know what steps to take from there.
How many people get blood clots?
Veinous thromboembolism (VTE), which is blood clots in the veins, is the most serious and most common type of blood clot in the UK.
According to the organisation Thrombosis UK, one in four people die from causes related to blood clots and in the west, every 37 seconds sees someone die from a VTE.
In terms of where blood clots originate, the charity says 55 to 60 percent of all VTE cases occur during or after hospitalisation.
Thrombosis UK says more people die from blood clots every year than the total number of people who die from AIDs, breast cancer and car accidents combined.
