Jakarta, CNBC Indonesia – Recent studies have shown that Covid-19 infection carries a very high risk of blood clots. In fact, this risk is higher than the side effects of the Covid-19 vaccine injection.
In a study published in the British Medical Journal on Friday (27/8/2021), researchers from the University of Oxford, the London School of Hygiene and Tropical Medicine, and several other UK universities and hospitals analyzed data from more than 29 million people who have received their first dose of the Oxford-AstraZeneca or Pfizer-BioNTech vaccine.
As a result, scientists saw a higher incidence of blood clots occurring in people infected with Covid-19 than patients who had received the corona vaccine.
“The researchers found that the risk of these side effects was much higher after infection with Covid-19 than after receiving the Oxford-AstraZeneca or Pfizer-BioNTech vaccines,” the report said. CNBC International.
The researchers estimated that within 28 days after the first dose of the Oxford-AstraZeneca vaccine, 66 people per 10 million were hospitalized or died of blood clots in the veins, compared with 12,614 per 10 million people who tested positive for the virus.
Meanwhile, an estimated 143 people per 10 million were hospitalized or died from the effects of blood clots after the first dose of Pfizer-BioNTech vaccine, compared to 1,699 who tested positive for Covid-19.
Previously, several cases of blood clots were reported after the injection of the Covid-19 vaccine dose. This made the world public worried and decided not to be vaccinated.
However, various health authorities, including the WHO, the European Medicines Agency, and the International Society on Thrombosis and Hemostasis, continue to emphasize that the risk of death is reduced by receiving the vaccine.
“People should be aware of this increased risk following Covid-19 vaccination and seek immediate medical attention if they develop symptoms, but also be aware that the risk is much higher and over a longer period of time if they are infected with SARS-CoV-2,” he said. Julia Hippisley-Cox, professor of clinical epidemiology and general practice at the University of Oxford.
“This large study has shown that there is a very small risk of clotting and other blood disorders after the first dose of Covid-19 vaccination. Although serious, the risk of this same outcome is much higher after SARS-CoV-2 infection,” stressed Aziz Sheikh, professor of primary care research & development at The University of Edinburgh.
