Coronavirus vaccine update: The clinical trials for the Covid-19 vaccine candidate developed by the University of Oxford, which was expected to start at PGIMER in Chandigarh, have been delayed by at least a week over safety approvals. Late-stage studies of AstraZeneca's Covid-19 vaccine candiate are on temporary hold while the company investigates whether a recipient's "potentially unexplained" illness is a side effect of the shot. The AstraZeneca-Oxford University vaccine is seen as a strong contender among dozens being developed globally.
