It is true that the vaccines used for immunization against the coronavirus leave some side effects. While these are not serious, there is a Covid-19 vaccine that appears to cause clots. The effects are: pain in the legs and chest, as well as in the left arm.
Why does Astrazeneca form clots
The vaccine created by Astrazeneca together with Oxford has had problems in recent days because it has been found that, in some cases, it leaves sequelae that can be serious.
These are blood clots that can form in the legs and can reach the heart or lungs. Although the cases are relatively few compared to those vaccinated who have not suffered this side effect, they have had repercussions within the scientific community and the world in general.
So much so that there are people who prefer not to be vaccinated with it, despite the fact that the benefits are greater than the effects it produces. What many researchers are wondering is: Why do some people have this side effect and others do not?
What causes clots
In an article published in Medical Express, Swedish researcher Eirik Tjønnfjord says: “There are some unfortunate people who have a reaction and whose bodies create these antibodies.”
In this sense, the reaction occurs due to the creation of antibodies combined with a decrease in platelet levels, but this reaction does not happen in all people who use the Covid-19 vaccine.
One of the common symptoms of these clots include pain in the chest and left arm, trouble breathing, and sweating. This indicates that the clots could affect the heart.
The point is that this problem is also part of the symptoms of Covid infection, which could be ambiguous if it is a problem caused by the vaccine or by the disease itself.
Another symptom is shortness of breath. It is one of the complications that can be risky, since it could cause pulmonary embolism. In fact, this symptom also occurs with the disease.
In this case, the clots can travel through the bloodstream to the lungs. This causes trouble breathing, shortness of breath, coughing up blood, and chest pain.
It also causes swelling in the legs, abdominal and headache pain; dizziness and blurred vision.
So isn’t it safe?
The side effects of this vaccine affect very few people. It is true that scientists are looking for ways to improve it and prevent it from occurring.
That is why it is necessary to monitor what are the effects that occur after receiving the doses to go to a medical center and avoid complications.
Meanwhile the only way coping with this disease is the vaccine and the protection measures that have been taken so far.
