Both KEM and Nair Hospitals will enrol 160 volunteers to participate in the last stage trial of Oxford’s COVID vaccine. As per reports, the volunteers should be healthy and must not have contracted COVID-19 in the past. All the volunteers will undergo a RT-PCR test to determine whether or not, they have been exposed to the novel coronavirus. While there is no upper age limit to participate in the trial, the minimum age is 18 years. It is also important that volunteers do not have any chronic health condition and must not be on immunosuppressants.
