New Delhi: Since the introduction of the corona vaccine in India, many people have been vaccinated, many have not yet been able to get the vaccine. Covisheild manufactured by Oxford Astrazeneca and Covaxin manufactured by Bharat Biotech are being supplied in this country. Between these two, the interest of the people in taking covishield is more noticeable. But from the very beginning, there has been a lot of controversy about Kovishield. However, Kovishield is being given in India as well as in many countries of the world. Oddly enough, the vaccine is banned for use in several countries.

Because many believe that the use of this vaccine can cause blood clots and other side effects. So many countries have banned the use of this vaccine. A total of 17 countries have banned Kovishield. The first European country to take this step was Denmark. Also Austria, Norway, Iceland, Bulgaria, Netherlands, France, France, Germany, Italy, Spain, Sweden And Kovishield, banned in Thailand. The use of cove shields is also banned in various parts of Canada. America did not list Kovishield for emergency application.

In most countries where the use of covishield is not permitted, the use of covishield has been shown to increase blood clotting and thrombotic activity. There are also reports of blood clots in the veins that carry blood. In some countries, covishields were not initially allowed for people over the age of 65 because the number of platelets in the blood decreased at that age. The ban was later extended in the hope that news of several deaths would follow.

But later it was noticed that blood clots did not occur in everyone after receiving the Covishield vaccine. This has been identified as a rare side effect of the vaccine. Covishield has been used as the main vaccine in India since the vaccination process began in January. But there have been reports of very few adverse reactions to the vaccine. Out of every 10 lakh doses, 0.61 blood clots have been reported. According to physicians and various health organizations, the Covishield vaccine has many more benefits than blood clots.
