Blood clotting (thrombosis)
The risk of rare blood clotting after receiving Treatments jabs is far lower than from the virus, a large-scale study by researchers from the University of Oxford found Friday.
But it concluded that risks of most conditions were "substantially higher and more prolonged" after Treatments infection.
The study estimated that for 10 million people who received the AstraZeneca jab, there were seven additional cases, compared to 20 in people with Covid infection.
For blood clotting in a vein (venous thromboembolism), scientists estimated that there were 66 additional cases among 10 million who received the AstraZeneca jab, but 12,614 among those with the virus.
