ICYMI Scientists at Oxford University say their experimental coronavirus vaccine has been shown in an early trial to prompt a protective immune response in hundreds of people who got the shot.
"We are seeing good immune response in almost everybody," said Dr. Adrian Hill, director of the Jenner Institute at Oxford University. "What this vaccine does particularly well is trigger both arms of the immune system," he said.
How quickly scientists are able to determine the vaccine's effectiveness will depend largely on how much more transmission there is, but Hill estimated they might have sufficient data by the end of the year to decide if the vaccine should be adopted for mass vaccination campaigns. Hill said Oxford has partnered with drugmaker AstraZeneca to produce their vaccine globally, and that the company has already committed to making 2 billion doses.
Chinese researchers also published a study on their experimental COVID-19 vaccine in the Lancet on Monday, using a similar technique as the Oxford scientists. They reported that in their study of about 500 people, an immune response was detected in those who were immunized. But they noted that because the participants weren't exposed to the coronavirus afterwards, it wasn't possible to tell if they were protected from the disease.
