AstraZeneca covid vaccine linked to another fatal blood clotting disorder
New Delhi: Researchers have found a link between the AstraZeneca Covid-19 vaccine and a rare but fatal blood clotting disorder. The disorder, known as vaccine-induced immune thrombocytopenia and thrombosis (VITT), has been associated with the AstraZeneca vaccine. A study from Flinders University in Australia and other international experts found that the antibodies responsible for VITT share identical molecular fingerprints with those found in cases of classic adenoviral vector VITT.
These findings have significant implications for vaccine safety and development, as lessons learned from VITT could be applicable to rare cases of blood clotting after adenovirus infections. AstraZeneca has acknowledged the rare side effects of its vaccine, including thrombotic thrombocytopenic syndrome (TTS), and has withdrawn marketing authorization from several global markets.
AstraZeneca's Covid-19 vaccine, known as Covishield in India and Vaxzevria in Europe, has been under scrutiny for its potential side effects. The study highlights the importance of understanding the mechanisms behind rare side effects of vaccines to enhance safety protocols and inform future vaccine development.
Healthcare authorities may need to reassess the risk-benefit profile of the AstraZeneca vaccine, especially in populations prone to rare blood clotting disorders. Continued research into the safety and efficacy of Covid-19 vaccines remains crucial for global vaccination efforts and public health protection.

Women’s Asian Champions Trophy: Deepika stars again as India cruise to semis with 3-0 win over Japan
Rajgir (Bihar), Nov 17: Defending champions India stormed into the semifinals of the Women’s Asian Champions Trophy with an unbeaten record, defeating Japan 3-0 here on Sunday.
Continuing her stellar form, star striker Deepika netted a quickfire brace from penalty corners in the final quarter to seal the victory, following vice-captain Navneet Kaur’s opener in the 37th minute.
With this win, India topped the league stage with maximum 15 points from five matches, ahead of Olympic silver medallists China (12 points).
India will take on fourth-placed Japan in the semifinal on Tuesday, while China will play third-placed Malaysia in the other last-four game.
Deepika, the tournament’s leading scorer, now boasts 10 goals, including four field goals, five penalty corners, and one penalty stroke, underscoring her dominance.
In the day’s other matches, Malaysia beat Thailand 2-0, while China defeated South Korea by an identical margin.
The Indians secured their first scoring chance in the form of back-to-back penalty corners in the eighth minute but Deepika's flick from the second effort was brilliantly saved by Japanese goalkeeper Yu Kudo.
India earned another penalty corner in the 13th minute but yet again wasted the chance.
The Indians continued to dominate and secured their fourth penalty corner in the 25th minute but once again Kudo rose to the occasion and made three brilliant saves to deny the hosts.
A minute after the change of ends, Kudo again came to Japan's rescue to deny Deepika.
India eventually broke the deadlock in the 37th minute through Navneet's brilliant reverse hit to the second post.
Deepika's brilliance
The Indians continued their domination and earned three back-to-back penalty corrners in the 47th minute and star dragflicker Deepika finally found the back of the net with a powerful low dragflick to open her account.
A minute later, the Indians secured another set piece and this time too Deepika struck again with a powerful flick into the top right corner, effectively sealing the match.
Credit must also go to the Indian defence, led brilliantly by Udita and Sushila Chanu, as they didn't let the Japanese take a single shot at the Indian goal.
Skipper Salima Tete, Neha and Sharmila Devi too were brilliant in the midfield, creating numerous chances for the forwardline with their runs and neat dribbling skills.
