Oxford starts human trials on COVID-19 vaccine: report

The BBC reports on an experimental COVID-19 vaccine that uses adenoviruses to deliver coronavirus genetic material, prompting the body to produce spike proteins and train the immune system. The vaccine aims to prepare the immune system to recognize and combat COVID-19. At the time of reporting, two volunteers had received the vaccine, with potential side effects including headache, fever, and muscle pain.

What is the primary role of the adenoviruses in the experimental COVID-19 vaccine?

• To replace the need for antibodies

• To strengthen the immune system directly

• To deliver coronavirus genetic material into human cells

• To cause a mild cold in recipients

How do the modified viruses help the immune system?

• By preventing any viral infections

• By teaching cells to produce spike proteins

• By producing antibodies immediately

• By directly attacking the coronavirus

What happens when vaccine recipients encounter the coronavirus after vaccination?

• Their immune system identifies and fights the virus

• Their immune system ignores the virus

• They become immune to all viruses

• They experience severe side effects

How many volunteers had received the vaccine at the time of the report?

• Two

• Fifty

• None

• Eight hundred

What are some potential side effects of the vaccine?

• Rash and itching

• Dizziness and fatigue

• Headache, fever, and muscle pains

• Nausea and vomiting
