Although they are “extremely rare,” neurological symptoms four to five days after getting vaccinated can be indicative of a problem.

A patient receives the AstraZeneca vaccine, this Wednesday, in Madrid.

The doctor specializing in Infectious Diseases and Clinical Genetics, Vicente Soriano, has described as symptoms after the COVID-19 vaccine that should concern us: sudden severe headache, loss of vision, or loss of strength.

Soriano, who was an advisor to the World Health Organization, has defined vaccines against this disease as a “treasure” in which “the benefits far outweigh the possible risks”.

He has related how the complications that can appear after the vaccine are of two types. The acute, arising in the following twelve hours; and the late ones, after three or four days.

The waters are the general to any vaccine and they consist of muscle pain, a little headache after two to three hours or chills and disappear in twelve to 24 hours. They are frequent and not very serious.

There is another acute complication that can be fatal, and that is a anaphylactic reaction (allergic: like when someone has a food allergy). It is exceptional, but it has been described. It appears during the minutes before the time to get the vaccine and is “very rare, it appears in one of every three million people vaccinated.”

Lastly, there are late complications, which are especially those that have been described with the AstraZeneca vaccine. Called thrombosis associated with thrombocytopenia and are of two types: in the head or in the abdomen. They appear after five, seven days and are “very infrequent, they appear in one per million”.

He explained how, with this information, the Medicines Agency has concluded that “the benefits of vaccination, by far, outweigh the possible risks.” “And that’s the message,” he highlighted

He pointed out how, up to April, 169 cases of cerebral thrombosis had been recorded in the European Union; and 53 in the abdomen after having vaccinated 45 million people with AstraZeneca. A “very low” proportion and before which “they will continue to study and see if they appear in other vaccines”.

How to know whether to worry: if after three, four, five days a very strong sudden headache appears, or a neurological complication: loss of strength, double vision … In this case, “you have to go to the Hospital and say that you received the vaccine and that you want to be evaluated. It can be diagnosed with a scanner, for example ”.

How our life will change after being vaccinated: “For the better”, he asserted. “The benefit in places where many people have been vaccinated is brutal, for example, Israel, the United Kingdom or some areas of California,” he highlighted.

“The vaccine works very well for avoiding serious forms, including AstraZeneca, is a treasure; the complications that are being seen should not reduce the rate of rapid vaccination that we need, this message is very important ”, the UNIR professor and director of the UNIR University Expert in Clinical Genetics and Personalized Medicine have also had an impact.

In this sense, he has pointed out how behind the information that is being given there is, also, “business interests because Moderna and Pfizer are from the United States, they are worth 35 and 55 euros and AstraZéneca is European (British, and the tension is with the bréxit) and it is only worth six euros ”.

“There are those who are interested in media noise; Moderna and Pfizer are private companies, they have their group that defends them directlyWhile AstraZeneca are companies that have government support and no one feels them very much theirs ”, he said.

With regard to releasing the patent, he recalled how with HIV antivirals when companies “made their summer” sold them as generics. He believed that the patent for the vaccine against COVID-19 should be released “so that third world countries have access as soon as possible.” In this sense, he recalled that “we are in a globalized world” and “the world is interconnected and, if we don’t all get vaccinated, the virus will continue to circulate. “

As for the mask, he has considered: “Stress can be reduced, but it will not disappear” because, even, all respiratory viruses “have fallen” so there is a clear “medical benefit” to wearing it.

“It is obvious that it is annoying and we want to see people’s faces, but it reduces the risk,” he said, noting how “just as you put on your jacket when you go out to avoid being cold, you will put on a comfortable mask.”
