Both KEM Hospital and Nair Hospital, centres for the ongoing Oxford vaccine trial for COVID-19, have finished administering the first dose to participants and have started with the second round. While both centres had asked for an additional target, Nair received the approval of the Indian Council of Medical Research (ICMR) and added 48 participants.

Late last month, a representation was sent to ICMR of adding more participants to the existing quota of 100 candidates for each hospital.
