NEW DELHI : Scientists at the Department of Biotechnology’s (DBT) are studying the long-term memory of covid-19 vaccination in the human body, including the jabs’ quality and durability.
The research outcome will have a bearing on future vaccine dosage strategies, including for booster doses. DBT secretary Rajesh Gokhale said: “Given the large-scale covid-19 vaccination in the country, the study aims to understand long-term immune responses in the population.
Memory studies are comparatively complex studies unlike antibody studies, and involve cell-based therapies that require cells’ isolation, tracking of cells, antigens and then looking at cells which is called cellular response.
Those require standardization of essays, isolating the viruses and looking at the population infected and non-infected. Response of one vaccine over another vaccine." This study is also expected to help the government devise public health responses to future pandemics and viruses. “We need to understand the long-term significance of our vaccination.
