UTOPIA Welcomes Representatives from HHS/ASPR, CDC, US Embassy, and Japan's Ministry of Health, Labour and Welfare
On 18 March 2024 UTOPIA was honored to welcomd a group of representatives from the U.S. Department of Health and Human Services (HHS)/ Administration for Strategic Preparedness and Response (ASPR), the U.S. Centers for Disease Control and Prevention (CDC)'s East Asia and Pacific regional office, the US Embassy, and Japan's Ministry of Health, Labour and Welfare.
The visit began with a short speech by Ms Dawn O‘Connell of HHS/ASPR. This was followed by a presentation on the "Japan Initiative for World-leading Vaccine Research and Development Centers " by Professor Ken Ishii, Deputy Director of UTOPIA, the flagship Center of the Initiative. The presentation was followed by a tour of the Biobank Japan facility, which is affiliated with the supporting institution at UTokyo. The tour was led by Professors Matsuda and Morisaki.

UTOPIA Seminar
Date/Time: Thursday, 18 January 2024 16:00 -
Place: Auditorium, 1st building, The Institute of Medical Science, The University of Tokyo
Topic: Antibody responses to SARS-CoV-2 infection and vaccination
Speaker: Florian Krammer, Department of Microbiology, Icahn School of Medicine at Mount Sinai, New York, USA
It is thought that mRNA-based vaccine-induced immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) wanes quickly, based mostly on short-term studies. We analyzed the kinetics and durability of the humoral responses to SARS-CoV-2 infection and vaccination using >8,000 longitudinal samples collected over a three-year period in New York City. Upon primary immunization, participants with pre-existing immunity mounted higher antibody responses faster and achieved higher steady-state antibody titers than naïve individuals. Antibody kinetics were characterized by two phases: an initial rapid decay followed by a stabilization phase with very slow decay. Booster vaccination equalized the differences in antibody levels between participants with and without hybrid immunity, but the antibody titers reached decreased with each successive antigen exposure. Breakthrough infections increased antibodies to similar titers as an additional vaccine dose in naïve individuals. Our study provides strong evidence that SARS-CoV-2 antibody responses are long- lasting, with initial waning followed by stabilization. In addition, this talk will also focus on the breadth of the induced antibody responses beyond SARS-CoV-2, mucosal immune responses, the functionality of non-neutralizing antibodies and development of novel vectored SARS-CoV-2 vaccines.
