Vaccine

Oxford University says trials of a coronavirus vaccine it is developing with pharmaceutical company AstraZeneca will resume, days after being paused because of a reported side effect in a patient in the U.K. In a statement, the university said that in large trials “it is expected that some participants will become unwell and every case must be carefully evaluated to ensure careful assessment of safety.” Though it would not disclose information about the patient’s illness, an AstraZeneca spokesman said this week that a woman had developed severe neurological symptoms that prompted the pause in testing.
