In 2022, as many as 92% of COVID deaths have been due to unvaccinated individuals. India is the second country which is having a vaccine tracker.
In 2022, as many as 92% of COVID deaths have been due to unvaccinated individuals, said the Indian Council of Medical Research Director-General, Dr. Balram Bhargava. At a press briefing on current Covid situation in the country, the ICMR chief, about vaccine effectiveness in mortality prevention, said that the first dose is responsible for 98.9% vaccine effectiveness, and if both doses are given, then it is 99.3% effective.
He said that vaccines development, deployment and impact have been scientifically measured.
About the vaccine development, he said that two different approaches — leveraging India’s scientific prowess and leveraging international sciences — were undertaken. Elaborating on the first, he said that research and development, product development, and large clinical trials were undertaken to develop two indigenous vaccines — one a whole virus vaccine and second a DNA vaccine, resulting into Covaxin and ZyCoV-D.
"Under the second approach, we had technology transfer, bridging studies, and augment Production which resulted into the development of four vaccines — Covishield, Covovax, Corbevax and Sputnik V," Dr. Bhargava said.
About Covaxin’s development, the ICMR chief said that preclinical studies were done on small animals like monkeys to establish the safety, immunity and dosage of vaccines.
About vaccine effectiveness, he said that the impact has been measured and shows high vaccination has reduced morbidity and mortality.
