Mornings begin early on the 200-acre campus of the All India Institute of Medical Sciences (AIIMS), located in the heart of the national capital of Delhi. Even as the rest of the city shakes off its slumber, there’s visible hustle at the hospital’s Department of Pulmonology. Phase II of clinical trials for a Covid-19 vaccine candidate is underway.
With no separate waiting area, the fifty-odd healthy volunteers—ranging from 18-65 years—sit outside in the open. The benches they occupy abut the hospital’s tuberculosis department, with a constant stream of infected patients flitting past them.
The volunteers are called in batches to receive the second dose of Bharat Biotech’s Covaxin.
