Researchers at the University of Oxford say Covid-19 leads to a risk of rare blood clots that's several-times higher than that of current vaccines, amid concerns that the jabs may be to blame for the potentially deadly condition.
The report released on Thursday says the risk of the rare condition known as cerebral venous thrombosis (CVT) following Covid-19 infection is “around 100 times greater than normal” and “several times higher” than it is post-vaccination or after flu.
Researchers looked at health records of 500,000 Covid-19 patients to estimate the absolute incidence of CVT in the two weeks following Covid-19 diagnosis, flu, or vaccination against coronavirus. They found that clotting is around eight times more likely to occur after contracting Covid-19 than after immunization with the AZ-Oxford Covid-19 vaccine. Compared to the vaccines made by Pfizer or Moderna, the risk of a CVT from Covid-19 is about 10 times greater.
The researchers, however, call for a cautious interpretation of the comparisons since data is still coming in....rt
