Get the Covid-19 vaccine offers sufficient protection against the virus, but can also cause someNon-serious side effects Such as fatigue, injection site pain, nausea, chills or mild fever, according to American centers for disease control and prevention (CDC). The most serious side effects that can cause vaccine have been deemed extremely rare, such asA blood coagulation reaction Caused by Johnson & Johnson vaccine in a very small number of cases. Now, a new case study has linkedBell paralysis with the vaccine against Pfizer, establishing a potential connection between a patient and the delayed side effect.

Research, which has been published in the newspaperBMJ case reportsAbout Jul 19, details the case of a 61-year-old patient who was admitted to the emergency room after starting to drool, lost the ability to close his right eye and could not move the right side of his Front about five years. hours after receipt of its first dose of the vaccine against Pfizer. After the CT analyzes and blood tests, "nothing of concern", the doctors diagnosed the man with Bell's paralysis, which is the medical term of the paralysis of your face muscles that is often temporary and prescribed him Steroids that have helped to completely solve the symptoms.

But the report notes that two days after receiving its second dose, the same patient was admitted to the hospital with moreViolent case of facial paralysis on his left side. "The occurrence of episodes immediately after each dose of vaccine strongly suggests that Bell's paralysis was attributed to the Pfizer-Biontech vaccine, although a causal relationship could be established," wroteBurrows of abigail, MD, the main author of the study of the Royal Surrey County Hospital Foundation of the NHS Foundation.

Since the second incident, the authors of the study report that the patient - to whom they notice was overweight, had high blood pressure, high cholesterol and type 2 diabetes - has almost completely recovered. "The patient has been advised to discuss future mRNA vaccines with [their doctor] on a case-by-case basis, taking into account the risk compared to each vaccine," he wrote.

This is not the first case ofBell paralysis has been reported as a potential side effect of CVIV-19 vaccine. During clinical trials, four volunteers who received the Pfizer-Biontech Vaccine Acka facial paralysis. In addition, three volunteers who took the Moderna vaccine also reported the disease, as well as a person from the placebo group.

However, some experts are cautious that there remains insufficient evidence to connect thePfizer vaccine with facial paralysis Despite the conclusions. "Bell paralysis is not all that rares a condition, and this could be a very unfortunate coincidence that the patient had two episodes at these times"Kevin McConwayProfessor emeritus of statistics applied at the open university who was not involved in the study, said in a declaration toNewsweek. "I think a key point is that even though Bell's paralysis of this patient was caused by the vaccine, a single case report can not tell you from Bell's Bell paralysis could be a vaccination . "

The authors of the study also emphasize that Covid vaccines are not the first to be potentially related to facial paralysis. "In 2004, the inactivated intranasal influenza vaccine considerably increases Bell's risk of paralysis and has been arrested," he concluded. "The increased incidence of Bell Paralysis has also been seen after the administration of other influenza and meningococcal vaccines, although a causal link has not been established."
