LONDON — Oxford University says trials of a coronavirus vaccine its developing with pharmaceutical company AstraZeneca will resume, days after pausing due to a reported side effect in a patient in Britain.
The university says 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.”
It says globally some 18,000 individuals have received study vaccines as part of the trial. It wouldn’t disclose the medical information about the illness for reasons of participant confidentiality but says it is “committed to the safety of our participants and the highest standards of conduct in our studies and will continue to monitor safety closely.”
Health experts say pauses in drug trials are commonplace to ensure safety and effectiveness.
Most patients with COVID-19 have mild to moderate symptoms. However, in a small proportion of patients, COVID-19 can lead to more severe illness, including death, particularly among those who are older or those who have chronic medical conditions.
COVID-19 spreads primarily through respiratory droplets produced when an infected person coughs or sneezes.
Symptoms include fever, cough, and difficulty breathing. Symptoms appear within 14 days of being exposed to an infectious person.
Virginia health officials urged the following precautions:
- Wash your hands often with soap and water for at least 20 seconds.

- Clean and disinfect frequently touched objects and surfaces.
