Signs of blood clotting and thrombocytopenia after Covid-19 vaccination 8
Associate Professor, Dr. Huynh Nghia, Deputy Dean of the Faculty of Medicine, Ho Chi Minh City University of Medicine and Pharmacy, affirmed that thrombotic complications (blood clotting) after vaccination against Covid-19 are rare.
Studies around the world show that with the Pfizer-BioNTech vaccine, cases of blood clotting are 0.2 per million first doses.
According to Associate Professor Nghia, blood clotting complications after AstraZeneca vaccination depend on genetic factors, underlying disease, lifestyle, current medications and factor V Leiden (a genetic mutation).
24 to 48 hours after vaccination, if the vaccinated person has symptoms such as fever, fatigue, headache or mild to moderate muscle pain, these are common reactions after vaccination.
After receiving the Covid-19 vaccine, the person receiving the injection needs to be observed at the injection site for 30 minutes and continue to self-monitor their health for the next 30 days.
The most common symptoms are thrombosis of blood vessels in the brain, internal organs and lungs.
Besides, symptoms of thrombocytopenia range from mild to severe, including bruises on the skin in the form of dots, patches, and hemangiomas.
When the above signs appear after the 4th day of vaccination, it is necessary to immediately go to the nearest medical facility or vaccination medical facility for examination, consultation and treatment. Associate Professor Nghia recommends that people who are vaccinated
Each dose of AstraZeneca’s Covid-19 vaccine is 0.5 ml.
On April 13, the US Food and Drug Administration (FDA) and the US Centers for Disease Control and Prevention (CDC) proposed to temporarily suspend the use of Johnson & Johnson’s Covid-19 vaccine to investigate a possible problem.
