COVID-19: Cerebral venous thrombosis after vaccination


On 6th August, a group of PhD published in The Lancet that:
A new syndrome of vaccine-induced immune thrombotic thrombocytopenia (VITT) has emerged as a rare side-effect of vaccination against COVID-19.

The Lancet, an international weekly medical journal, reports that a new syndrome of vaccine-induced immune thrombotic thrombocytopenia (VITT) has emerged after vaccination for COVID. According to reports, cerebral venous thrombosis (CVT) is the most common manifestation of VITT and certain CVT cases have been determined as being vaccine-induced.

Data collected earlier this year from 99 patients among 43 U.K. hospitals show that after four patients were excluded because tests showed no definitive evidence of cerebral venous thrombosis, 70 of the remaining 95 patients had VITT, and 25 did not. According to the study, death occurred more frequently in patients with VITT-associated CVT as compared with the non-VITT control group

After the introduction of the AstraZeneca vaccine, five cases of severe VITT were reported in Norway, with four of those cases being CVT, according to reports. A similar condition was noted with the Johnson & Johnson vaccine and case reports also associate two mRNA vaccines — Moderna and Pfizer —with thrombocytopenia, only with slightly different symptoms.

Globally, more than 4·1 million people have died from COVID-19.
In response to this public health emergency, several vaccines against COVID-19 have been developed, with more than 3·7 billion doses administered worldwide. After the introduction of the adenovirus vector vaccine ChAdOx1 (Oxford–AstraZeneca), five cases of severe venous thrombosis with thrombocytopenia were reported in Norway, each starting 7–10 days after administration of the first vaccine dose. Four of these cases had cerebral venous sinus thrombosis.

This syndrome has since been termed vaccine-induced immune thrombotic thrombocytopenia (VITT).

  1. Thanks for enabling me to get new suggestions about pc’s. I also hold the belief that certain of the best ways to help keep your notebook in best condition is by using a hard plastic-type material case, as well as shell, that suits over the top of one’s computer. Most of these protective gear tend to be model targeted since they are manufactured to fit perfectly above the natural covering. You can buy these directly from the vendor, or via third party places if they are intended for your mobile computer, however not all laptop may have a cover on the market. Just as before, thanks for your guidelines.
