The interesting part is that India did not use the mRNA products that richer, Western countries used. They used a traditional vaccine with chemically pulverized viral particles. If their vaccine is causing this it’s probably because of poor quality control.

India began administration of COVID-19 vaccines on 16 January 2021. As of 1 August 2022, India has administered over 2.04 billion doses overall, including first, second and precautionary (booster) doses of the currently approved vaccines.[2][3] In India, 94% of the eligible population (12+) has received at least one shot, and 86% of the eligible population (12+) is fully vaccinated.[4][5]
India initially approved the Oxford–AstraZeneca vaccine (manufactured under license by Serum Institute of India under the trade name Covishield) and Covaxin (a vaccine developed locally by Bharat Biotech). They have since been joined by the Sputnik V (manufactured under license by Dr. Reddy's Laboratories, with additional production from Serum Institute of India being started in September[6][7]), Moderna vaccines, Johnson & Johnson vaccine and ZyCoV-D (a vaccine locally developed by Zydus Cadila)[a][b] and other vaccine candidates undergoing local clinical trials.
According to a June 2022 study published in The Lancet, COVID-19 vaccination in India prevented an additional 4.2 million deaths from December 8, 2020, to December 8, 2021.[8][9]
