5.Virological Research on the Novel Coronavirus (SARS-CoV-2)

Research Overview

Since the emergence of the novel coronavirus (SARS-CoV-2) in 2019, waves of infections driven by emerging variants have continued to recur. Utilizing a biosafety level (BSL) 3 laboratory, we are addressing the following virological challenges:

  1. Evaluation of the Inactivation Effect of New Disinfectants on SARS-CoV-2
    We assess the inactivation effect of candidate disinfectants on SARS-CoV-2 in vitro.
  2. Research on the Pathological Analysis of SARS-CoV-2
    We estimate vaccine efficacy by tracking the levels of neutralizing antibodies in the serum of vaccinated individuals. In addition, we study the pathology of SARS-CoV-2 by evaluating the virus's replication capacity in various cell types.
