In order to see how much the effect and persistence of the new coronavirus vaccine will differ depending on age, a group of Kyoto University targeted about 200 people who received the vaccine, and the changes in immune cells after vaccination. And so on.
The research will be conducted by Professor Yoko Hamasaki of the Center for iPS Cell Research and Application, Kyoto University, who specializes in immunology, and a group formed at the Hospital of the Faculty of Medicine.
According to the group, the plan is to have about 100 people aged 65 and over, each of whom is a medical worker at the hospital and a publicly recruited person, cooperate to collect blood six times in the year before and after vaccination. about it.
Then, we will analyze the value of the antibody that suppresses the action of the virus and the change in immune cells, and investigate the difference in the effect of the vaccine and its persistence depending on the age.
Professor Hamasaki said, "Immune cells that attack the virus are known to decrease or function with age. Especially, if the persistence of the effect on the elderly can be elucidated, the elderly at high risk will be in the future. It is useful for considering how often to inoculate the virus. "
