The Director of Public Health and Preventive Medicine, Government of Tamil Nadu was appointed as principal investigator. It would engage healthy individuals above 18 years of age.
It would be jointly carried out by the National Institute of Research in Tuberculosis, Chennai and ICMR. The Minister told reporters that the trial was all set to begin in the city. Official sources said the vaccine’s safety would be tested at RGGGH, while the immunogenicity would be evaluated at SRIHER. Each institute would have 150 participants each.
The Minister, in the release, said that the vaccine stimulated T-cell response in the body in 14 days. These T-cells, which are white blood cells, attacked the cells infected by coronavirus.
