New Delhi, Aug 24: The phase 2 human clinical trial of the Oxford COVID-19 vaccine candidate by Pune-based Serum Institute of India (SII) is set to begin from Tuesday.

The observer-blind, randomised controlled study to determine the safety and immunogenicity of ''Covishield'' on healthy Indian adults will begin at Bharati Vidyapeeth Medical College and Hospital in Pune, sources said.

Serum Institute of India has partnered with British-Swedish pharma company AstraZeneca for manufacturing the COVID-19 vaccine candidate, developed by the University of Oxford.

"We have got all approvals from the Central Drugs Standard Control Organisation (CDSCO). We are going to start the human clinical trial process at the Bharati Vidyapeeth (Deemed to be University) Medical College and Hospital from August 25. "We are sure that in line with the philosophy of our group, we are going to make available a world class COVID-19 vaccine for people of our country and make our country 'AatmaNirbhar'," Prakash Kumar Singh, Additional Director, Government and Regulatory Affairs, Serum Institute of India (SII) said.

As a rapid regulatory response, the Drugs Controller General of India (DCGI) on August 3 had given nod to the Pune Serum Institute of India (SII) for conducting phase 2 and 3 human clinical trials of the Oxford COVID-19 vaccine candidate in the country.

The trials are to be conducted across 17 selected sites, including AIIMS Delhi, B J Medical College in Pune, Rajendra Memorial Research Institute of Medical Sciences (RMRIMS) in Patna, Post Graduate Institute of Medical Education and Research in Chandigarh, AIIMS-Jodhpur, Nehru Hospital in Gorakhpur, Andhra Medical College in Visakhapatnam and JSS Academy of Higher Education and Research in Mysore, SII sources had said.

Around 1,600 people aged above 18 years are likely to participate in the trials.

Initial results of the first two-phases of trials of the vaccine conducted in five trial sites in the UK showed it has an acceptable safety profile and homologous boosting increased antibody responses, sources had said.
