How effectively do vaccine prevent serious cases? ICMR to find out | India News


PUNE: The Indian Council of Medical Research (ICMR), along with the Chennai-based National Institute of Epidemiology (NIE), has launched a nationwide study to determine vaccine effectiveness in preventing severe Covid-19 infection.
The study will be carried out at 11 sites across 10 cities.
A senior scientist with the team said the research will assess real-world efficacy of the Covid vaccines.
“It will track nearly 3,900 citizens. Of these, 1,300 will be Covid-positive people who were hospitalised after vaccination. The rest will be people who have tested negative (via RT-PCR), but have been vaccinated,” the scientist said, adding that the research will help determine true vaccine ability, especially since there have been reports of people testing positive (and even hospitalised with Covid) after inoculation.
NIE director Dr Manoj Murhekar said the study will provide information on real-world vaccine effectiveness against severe Covid. The ICMR had recently asked all states to collect data of people hospitalised after vaccination, to lay the groundwork for research into efficacy. Experts have stated that post-vaccine Covid is mostly mild. But they said a real-world study would help put minds at ease.
