Although there have been some cases of thrombosis in vaccinated people, the EMA confirmed on April 7 that this is a “rare” side effect, since in Spain five cases of the 985,528 injected doses have been reported.
Although there are people who are concerned about the possible side effects of vaccines against him coronavirus, it should also be known that there are other medicines that are on the market that can induce thrombosis.
In fact, there is virtually no zero risk with any drug, as he pointed out. Pepe Alcamín, virologist and researcher Instituto Carlos III de Madrid on TVE. “All medications have risks, none have zero risk. In this case it is a very low risk: below one in 10,000 cases of adverse effects.
Contraceptives, 100 affected per 100,000
The latest data collected by the EMA indicated that the probability of suffering a thrombus with the coronavirus vaccine was 1 for every 100,000 inhabitants. A lower figure when compared to that of the hormonal contraceptives, which pose a higher risk of thrombosis.
For example, one of the most popular brands of contraceptive pills indicates in its package insert that there is a probability of between 90 and 120 cases in 100,000. These combined hormonal contraceptives are the result of mixing estrogen with progestin.
For those women who are at high risk of thrombosis, simple contraceptives are prescribed, which do not contain estrogen derivatives. Here the risk drops to 10 cases per 100,000, much lower, although there is still no zero risk.
Corticosteroids Outweigh Vaccine Risks
Another of the drugs that pose a risk of thrombosis are corticosteroids such as prednisone. This medicine is usually taken for inflammations and can cause asthma or a rash, among other symptoms. This carries a low risk, although it can be suffered by 1,000 people per 100,000.
The antipsychotics that are often used to treat schizophrenia or depression also carry risks with thrombosis. Specifically, it can be found in the olanzapine, which can lead to blood clots, although this is a rare side effect, affecting up to 1,000 cases per 100,000.
Young women, the most affected
The European Medicines Agency reported that the people most affected by thrombus side effects had been women under the age of 55.
Until March 21, in Spain 11,182 adverse cases have been reported, corresponding to 183 cases per 100,000 doses. However, keep in mind that these side effects do not have to be related to vaccination. They have only been reported to study and investigate their relationship with their inoculation.
