36 people with blood clotting disorders after vaccination Covid-19 – VnExpress


AmericaThe day after receiving her first dose of Moderna vaccine, 72-year-old Luz Legaspi woke up with bruises on her hands and feet, blistering in her mouth.

She was hospitalized in New York City on January 19 and was determined to have thrombocytopenia – an essential component for blood clotting.

The situation was even more serious for Gregory Michael, 56, who is an obstetrician in Miami Beach. He developed the same symptoms three days after Pfizer-BioNTech’s Covid-19 vaccination. Two weeks later, he died of cerebral hemorrhage and stroke.

However, these are only a handful of cases and there is no definitive conclusion as to whether this blood disorder is related to the Covid-19 vaccine.

More than 31 million people in the US have received at least one dose of Covid-19 vaccine. These 36 blood problems have been reported to the vaccine negative response monitoring system (VAERS), as of the end of January. These people have been linked to the Pfizer-BioNTech or Moderna vaccine, only two products are allowed for emergency use in the US so far.

But the reporting system only shows the problems described by the healthcare provider or the patient after vaccination, and does not indicate whether the injections are actually causing the problem.

Officials from the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) say they are reviewing reports, but to date, the incidence of this symptom in people Vaccination is not higher than usual rates in the US population, so cases may be considered random.

Pfizer said it takes the reports of side effects very seriously and added it was aware of cases of thrombocytopenia in injecters. Moderna also issued a statement, not mentioning the question of a platelet disorder, but said the company continuously monitors the safety of the Covid-19 vaccine using all sources of data and regularly shares it. Safety information with regulatory agencies.

Hematologists with expertise in immune thrombocytopenia say they suspect the vaccine may play a role. However, they said that cases of symptoms like these after getting vaccinated are very rare. This may be the result of an unknown trend in some people towards vaccines. Acute immune thrombocytopenia that prevents blood from clotting properly occurs when the immune system attacks a patient’s own platelets or the cells in the bone marrow that make platelets.
