Coronavirus vaccine blow as Oxford trial faces another delay to investigate side effects

The hotly anticipated University of Oxford vaccine faces knock-on delays with its trials. A month-long pause in the jab's development could mean volunteers who had already been given one shot may not be able to get the planned second. The delay is due to American regulators investigating potential side effects, the Times reports. A previous delay on September 6 was triggered by AstraZenaca, which is developing the vaccine with Oxford, after a trial participant in the UK fell ill. Other people who had received the first shot were due for a second one next week, which has now been cancelled.
