Covishield vaccine has had more benefits than risks, says study by Kozhikode doctors
The HinduAt a time when the safety aspects of the Covishield vaccine have kicked up a row, a retrospective study by two doctors from Kozhikode has claimed that its risks are minimal in view of the benefits. The controversy arose after pharmaceutical company AstraZeneca admitted in the High Court of London, United Kingdom, that its vaccine against COVID-19 had the potential to cause thrombosis with thrombocytopenia syndrome, a rare side-effect associated with blood clotting in the brain. The study examined the severe adverse reactions reported between January 16, 2021, when the vaccine was launched in the country, and May 17, 2022. A total of 3,023 adverse reactions, including allergic reactions, blood clotting, and cardiovascular events, were reported, according to government data. Dr. Jayakrishnan pointed out that vaccine-induced thrombocytopenia in European countries was reported to be four per one million.
