JUST IN: The results of the Phase I/II coronavirus vaccine trial from a team of scientists at Oxford University found that it produces a strong immune response from participants.
Dr. Ashish Jha, director of the Harvard Global Health Institute, reacts to study results expected to show one vaccine might provide a"double defense" against COVID-19.A team of scientists at the University of Oxford released promising results showing their COVID-19 vaccine appears safe in an early-stage study — welcome news for one of the most advanced vaccine programs in the world.
The University of Oxford has partnered with the pharmaceutical company AstraZeneca, which received a $1.2 billion investment from the U.S. government to help speed up development and ensure U.S. citizens have access to the vaccine should it prove successful. Other vaccines, such as those made by Moderna and Pfizer/BioNTech, also showed their capacity to generate these so-called"neutralizing" antibodies in Phase 1 studies.Antibodies, however, are not the only part of our immune system. New research finds that among people who have been infected and recovered from the virus, antibodies may fade more rapidly than we had hoped, prompting scientists to take a closer look at T cells, another virus-fighting part of the immune system.
He added that it makes sense that Oxford's vaccine would produce killer T-cells because historically vaccines that use the type of technology can induce killer T-cells. According to Offit, it’s the helper T-cells and antibodies that are more likely to be important factors to long-term COVID-19 immunity.
